00:00:14,480 --> 00:00:21,359
this morning we've got Maxim Lynn Maxim

5
00:00:18,539 --> 00:00:23,160
is a freelance developer who's Co Who

6
00:00:21,359 --> 00:00:26,220
currently specializes in flutter

7
00:00:23,160 --> 00:00:29,039
development in his work as a developer

8
00:00:26,220 --> 00:00:32,700
relations engineer at code Magic

9
00:00:29,039 --> 00:00:36,600
in today's talk Maxim will take us

10
00:00:32,700 --> 00:00:39,899
on a journey into the fascinating Niche

11
00:00:36,600 --> 00:00:44,160
world of electronic music making using

12
00:00:39,899 --> 00:00:45,059
Hardware synthesizers Samplers and drum

13
00:00:44,160 --> 00:00:48,440
machines

14
00:00:45,059 --> 00:00:48,440
please welcome Maxim

15
00:00:50,860 --> 00:00:54,480
[Applause]

16
00:00:52,320 --> 00:00:56,340
oh thanks very much everyone and thank

17
00:00:54,480 --> 00:00:57,239
you very much for coming to my talk this

18
00:00:56,340 --> 00:00:59,160
morning

19
00:00:57,239 --> 00:01:02,100
um yeah so

20
00:00:59,160 --> 00:01:04,920
just a quick bit more about me I've a

21
00:01:02,100 --> 00:01:07,799
long time Android developer who now does

22
00:01:04,920 --> 00:01:09,420
flutter for his sins and more recently

23
00:01:07,799 --> 00:01:12,479
I've become a developer relations

24
00:01:09,420 --> 00:01:16,200
engineer at code magic which is a mobile

25
00:01:12,479 --> 00:01:19,140
and flutter Focus CI CD service

26
00:01:16,200 --> 00:01:21,360
and also in terms of community like I've

27
00:01:19,140 --> 00:01:22,740
been involved with our local Google

28
00:01:21,360 --> 00:01:24,479
developer group here in Melbourne for

29
00:01:22,740 --> 00:01:26,700
quite a while and we also a few years

30
00:01:24,479 --> 00:01:29,040
ago spun off uh flood in Melbourne from

31
00:01:26,700 --> 00:01:31,380
that for people interested in flood

32
00:01:29,040 --> 00:01:34,740
development here in Melbourne

33
00:01:31,380 --> 00:01:37,500
now all of these things as you may have

34
00:01:34,740 --> 00:01:40,500
noticed have absolutely zero to do with

35
00:01:37,500 --> 00:01:41,939
music and music production and to be

36
00:01:40,500 --> 00:01:45,000
honest like until about a couple of

37
00:01:41,939 --> 00:01:47,700
years ago I had absolutely no idea about

38
00:01:45,000 --> 00:01:50,520
anything at all involved with music

39
00:01:47,700 --> 00:01:52,740
apart from listening to it so I have the

40
00:01:50,520 --> 00:01:55,680
distinct honor according to my year nine

41
00:01:52,740 --> 00:01:59,759
music feature of having the lowest ever

42
00:01:55,680 --> 00:02:01,920
score on note and Rhythm recognition

43
00:01:59,759 --> 00:02:03,720
tests so I'm not only tone deaf but

44
00:02:01,920 --> 00:02:06,420
Rhythm deaf

45
00:02:03,720 --> 00:02:09,119
however this did not stop me during

46
00:02:06,420 --> 00:02:13,020
covert from having an exchange with a

47
00:02:09,119 --> 00:02:15,900
person called Bob Nystrom Bob is in his

48
00:02:13,020 --> 00:02:18,480
day job on the dart of on the dart

49
00:02:15,900 --> 00:02:21,300
language team writing the dark compiler

50
00:02:18,480 --> 00:02:24,000
but in one of his Hobbies he actually

51
00:02:21,300 --> 00:02:26,160
makes electronic music and I happen to

52
00:02:24,000 --> 00:02:28,080
watch one of his videos

53
00:02:26,160 --> 00:02:30,239
and afterwards

54
00:02:28,080 --> 00:02:32,819
um just sent him a message on I'll

55
00:02:30,239 --> 00:02:35,220
tagged him on uh Twitter saying this was

56
00:02:32,819 --> 00:02:38,640
amazing I was so impressed how he and

57
00:02:35,220 --> 00:02:41,040
other colleagues who I work with uh so

58
00:02:38,640 --> 00:02:43,680
uh into music and very often quite

59
00:02:41,040 --> 00:02:47,160
talented musicians and I just wished I

60
00:02:43,680 --> 00:02:49,500
had like a modicum of that and Bob's

61
00:02:47,160 --> 00:02:52,019
rather faithful words are well it's

62
00:02:49,500 --> 00:02:55,080
never too late so I went well

63
00:02:52,019 --> 00:02:56,819
I think this was just before the next uh

64
00:02:55,080 --> 00:02:59,220
lockdown that we had here in Melbourne

65
00:02:56,819 --> 00:03:01,440
so it's not that I had a lot of time on

66
00:02:59,220 --> 00:03:02,819
my hands with kids at home but like I

67
00:03:01,440 --> 00:03:04,980
thought well this might be a good chance

68
00:03:02,819 --> 00:03:06,959
to learn a bit more about it and down

69
00:03:04,980 --> 00:03:08,040
the rabbit hole I went

70
00:03:06,959 --> 00:03:11,099
so

71
00:03:08,040 --> 00:03:15,239
in terms of what I'm going to be talking

72
00:03:11,099 --> 00:03:16,700
about there's a huge huge area when it

73
00:03:15,239 --> 00:03:18,840
comes to

74
00:03:16,700 --> 00:03:21,239
electronic music not just music in

75
00:03:18,840 --> 00:03:24,120
general and so there are niches within

76
00:03:21,239 --> 00:03:27,180
sub niches within sub niches and the one

77
00:03:24,120 --> 00:03:27,980
I want to talk about today is

78
00:03:27,180 --> 00:03:31,019
um

79
00:03:27,980 --> 00:03:34,019
using electronic devices to make

80
00:03:31,019 --> 00:03:35,640
electronic music and so here's to give

81
00:03:34,019 --> 00:03:37,560
you a flavor of it this is the video

82
00:03:35,640 --> 00:03:40,260
from my memory the first one that I

83
00:03:37,560 --> 00:03:44,060
watched of Bob's he's made quite a few

84
00:03:40,260 --> 00:03:44,060
um oh hang on I better unmute that

85
00:03:45,720 --> 00:03:49,440
hopefully that comes up on

86
00:03:47,710 --> 00:03:52,260
[Music]

87
00:03:49,440 --> 00:03:54,720
yeah it starts quiet so this is the I

88
00:03:52,260 --> 00:03:58,379
think the first performance that I saw

89
00:03:54,720 --> 00:04:00,720
um of Bob using uh this device which is

90
00:03:58,379 --> 00:04:02,819
a an electribe 2 made by a company

91
00:04:00,720 --> 00:04:04,799
called Korg which is fairly big in the

92
00:04:02,819 --> 00:04:09,239
music scene while watching this so I

93
00:04:04,799 --> 00:04:11,340
wonder just show of hands who knows or

94
00:04:09,239 --> 00:04:12,420
has dabbled in electronic music

95
00:04:11,340 --> 00:04:14,280
production

96
00:04:12,420 --> 00:04:16,620
so someone who might know what a

97
00:04:14,280 --> 00:04:18,540
synthesizer is versus a sampler oh

98
00:04:16,620 --> 00:04:20,880
awesome so there's a few people uh so

99
00:04:18,540 --> 00:04:23,940
I'll try and keep um

100
00:04:20,880 --> 00:04:26,580
my explanation short but um enough to

101
00:04:23,940 --> 00:04:28,440
cover people who aren't across it so why

102
00:04:26,580 --> 00:04:31,139
I said performance is that in this case

103
00:04:28,440 --> 00:04:32,460
it's a standalone music or instrument or

104
00:04:31,139 --> 00:04:34,080
some people might say it's just a device

105
00:04:32,460 --> 00:04:36,479
but I think it's an instrument because

106
00:04:34,080 --> 00:04:39,900
it involves the person in this case Bob

107
00:04:36,479 --> 00:04:42,479
actually performing like making like

108
00:04:39,900 --> 00:04:44,280
changes to the music on the fly as you

109
00:04:42,479 --> 00:04:46,740
would with maybe a more traditional

110
00:04:44,280 --> 00:04:49,500
instrument like a piano or guitar or

111
00:04:46,740 --> 00:04:51,240
electronic synthesizer where he's like

112
00:04:49,500 --> 00:04:54,180
manipulating

113
00:04:51,240 --> 00:04:56,580
um which parts or tracks are playing

114
00:04:54,180 --> 00:04:59,040
he's applying filters or removing

115
00:04:56,580 --> 00:05:02,160
filters to different parts that are

116
00:04:59,040 --> 00:05:04,440
playing so it really is a performance

117
00:05:02,160 --> 00:05:05,940
um this in this one I think this is only

118
00:05:04,440 --> 00:05:07,979
this first one so you probably admit

119
00:05:05,940 --> 00:05:09,600
this is probably the lowest key one but

120
00:05:07,979 --> 00:05:11,600
there are others which are much more

121
00:05:09,600 --> 00:05:15,240
involved and like there are some

122
00:05:11,600 --> 00:05:18,419
professional musicians who through these

123
00:05:15,240 --> 00:05:20,400
performances and it involves a large

124
00:05:18,419 --> 00:05:22,259
amount of manual dexterity and

125
00:05:20,400 --> 00:05:24,539
coordination to control the gear that

126
00:05:22,259 --> 00:05:26,759
they're using to perform with so I'll

127
00:05:24,539 --> 00:05:28,740
just stop that there

128
00:05:26,759 --> 00:05:31,259
and

129
00:05:28,740 --> 00:05:32,400
oops

130
00:05:31,259 --> 00:05:34,080
move on

131
00:05:32,400 --> 00:05:36,180
so

132
00:05:34,080 --> 00:05:38,039
what Bob was using there was a Groove

133
00:05:36,180 --> 00:05:39,600
box and the reason I asked for show of

134
00:05:38,039 --> 00:05:41,759
hands was I thought I better know if

135
00:05:39,600 --> 00:05:43,860
everyone knows what one is I don't need

136
00:05:41,759 --> 00:05:46,500
to explain it but in this case I'll give

137
00:05:43,860 --> 00:05:49,500
you a quick rundown so Groove boxes are

138
00:05:46,500 --> 00:05:51,720
these Standalone pieces of hard musical

139
00:05:49,500 --> 00:05:55,560
Hardware like Bob was using that

140
00:05:51,720 --> 00:05:57,479
contains normally they're not always but

141
00:05:55,560 --> 00:06:00,300
they'll normally contain a synthesizer

142
00:05:57,479 --> 00:06:02,759
or a sampler a synthesizer synthesizes

143
00:06:00,300 --> 00:06:05,520
music from just raw waveform Samplers

144
00:06:02,759 --> 00:06:09,960
will play back samples like little tiny

145
00:06:05,520 --> 00:06:11,880
recordings of music or some other sound

146
00:06:09,960 --> 00:06:13,620
they'll often have a built-in drum

147
00:06:11,880 --> 00:06:14,880
machine so the thing that like in the

148
00:06:13,620 --> 00:06:18,180
80s people thought might replace

149
00:06:14,880 --> 00:06:20,100
drummers but didn't really but I used a

150
00:06:18,180 --> 00:06:22,620
lot throughout music production

151
00:06:20,100 --> 00:06:24,660
especially in pop music and sequences

152
00:06:22,620 --> 00:06:27,060
because it's enough to it's not enough

153
00:06:24,660 --> 00:06:30,180
to just have a sequence a synthesizer or

154
00:06:27,060 --> 00:06:31,860
a sampler that produces notes or sounds

155
00:06:30,180 --> 00:06:35,580
you want something that sequences it

156
00:06:31,860 --> 00:06:39,479
into a track into a score of music so

157
00:06:35,580 --> 00:06:41,460
all these things basically make up a

158
00:06:39,479 --> 00:06:43,620
Groove what's called a Groove box

159
00:06:41,460 --> 00:06:45,479
because you can often get Standalone

160
00:06:43,620 --> 00:06:47,220
pieces of Hardware that do just one of

161
00:06:45,479 --> 00:06:51,060
these functions but Groove boxes are

162
00:06:47,220 --> 00:06:53,460
kind of uh a genre or like a set of

163
00:06:51,060 --> 00:06:56,039
instruments that cover

164
00:06:53,460 --> 00:06:58,080
like all most of all of those functions

165
00:06:56,039 --> 00:07:00,900
and this is just for something that's

166
00:06:58,080 --> 00:07:03,000
really a niche of electronic music

167
00:07:00,900 --> 00:07:05,400
production because I should say that

168
00:07:03,000 --> 00:07:09,300
recently most electronic music producers

169
00:07:05,400 --> 00:07:11,160
use uh software called doors or diws

170
00:07:09,300 --> 00:07:13,620
digital audio workstations basically the

171
00:07:11,160 --> 00:07:16,440
audio equivalent of a video editor

172
00:07:13,620 --> 00:07:18,660
to produce their music but there is like

173
00:07:16,440 --> 00:07:21,840
this Niche like I said or

174
00:07:18,660 --> 00:07:23,400
um a sub Niche where people do doorless

175
00:07:21,840 --> 00:07:25,860
what they call dawless music which is

176
00:07:23,400 --> 00:07:27,599
producing electronic music just with

177
00:07:25,860 --> 00:07:29,039
these Standalone devices and for

178
00:07:27,599 --> 00:07:30,900
something that is a niche it's amazing

179
00:07:29,039 --> 00:07:33,840
just the amount of variety of devices

180
00:07:30,900 --> 00:07:36,000
from a number of quite a large number of

181
00:07:33,840 --> 00:07:38,699
Manufacturers some well-known ones like

182
00:07:36,000 --> 00:07:40,620
Yamaha or Roland that people who might

183
00:07:38,699 --> 00:07:42,900
say use electrical electronic

184
00:07:40,620 --> 00:07:46,220
synthesizers or pianos would recognize

185
00:07:42,900 --> 00:07:49,380
those names whereas others like electron

186
00:07:46,220 --> 00:07:51,360
are much more Niche they focus just on

187
00:07:49,380 --> 00:07:53,099
these devices and are much smaller

188
00:07:51,360 --> 00:07:55,020
companies but it's amazing like just the

189
00:07:53,099 --> 00:07:57,840
variety so the one in the middle here

190
00:07:55,020 --> 00:07:59,759
there I've got uh here with me today

191
00:07:57,840 --> 00:08:03,120
this is the circuit Track by a company

192
00:07:59,759 --> 00:08:04,860
called Novation in the UK now the

193
00:08:03,120 --> 00:08:08,819
interesting thing you might notice with

194
00:08:04,860 --> 00:08:11,900
that is the complete absence of any

195
00:08:08,819 --> 00:08:16,800
screen there is the UI consists of

196
00:08:11,900 --> 00:08:18,780
buttons which light up dials and rotary

197
00:08:16,800 --> 00:08:20,460
encoders there but there's no screen so

198
00:08:18,780 --> 00:08:22,319
the whole can it's a fairly complex

199
00:08:20,460 --> 00:08:24,720
piece of equipment but there is no

200
00:08:22,319 --> 00:08:27,539
screen which in today's

201
00:08:24,720 --> 00:08:28,979
um day and age if you like is quite

202
00:08:27,539 --> 00:08:30,720
unusual like we're so used to having

203
00:08:28,979 --> 00:08:33,300
basically a large high definition screen

204
00:08:30,720 --> 00:08:34,919
in our pockets that having an electronic

205
00:08:33,300 --> 00:08:37,560
device and controlling it with no screen

206
00:08:34,919 --> 00:08:40,140
at all probably seems a bit unusual to

207
00:08:37,560 --> 00:08:42,659
people these days now the other thing

208
00:08:40,140 --> 00:08:45,540
that all these devices had in common was

209
00:08:42,659 --> 00:08:48,240
that they are proprietary not even open

210
00:08:45,540 --> 00:08:51,000
source let alone open Hardware these are

211
00:08:48,240 --> 00:08:54,180
completely closed I briefly owned the

212
00:08:51,000 --> 00:08:56,940
blue one there the electron that Bob was

213
00:08:54,180 --> 00:08:59,760
playing just in a different colored

214
00:08:56,940 --> 00:09:00,899
version and there was a chap online I

215
00:08:59,760 --> 00:09:02,640
think he's based in England he was

216
00:09:00,899 --> 00:09:06,240
reverse engineering the firmware and

217
00:09:02,640 --> 00:09:09,600
binary patching bits of it to change or

218
00:09:06,240 --> 00:09:11,820
modify or add functionality but that was

219
00:09:09,600 --> 00:09:13,440
just like I I got into that for a little

220
00:09:11,820 --> 00:09:14,880
bit but that was just crazy stuff like I

221
00:09:13,440 --> 00:09:18,420
have better things to do in my life than

222
00:09:14,880 --> 00:09:20,519
binary patch a proprietary firmware from

223
00:09:18,420 --> 00:09:23,160
a manufacturer who cares nothing about

224
00:09:20,519 --> 00:09:24,480
updating or supporting the device that

225
00:09:23,160 --> 00:09:25,980
they are still like not that they've

226
00:09:24,480 --> 00:09:27,959
abandoned that they're still selling in

227
00:09:25,980 --> 00:09:29,880
the shops but they have not sent out an

228
00:09:27,959 --> 00:09:33,360
update a firmware update for like about

229
00:09:29,880 --> 00:09:35,459
four years so instead I kind of got

230
00:09:33,360 --> 00:09:38,519
inspired to think about well what about

231
00:09:35,459 --> 00:09:40,260
a DIY oh I groove box like being a

232
00:09:38,519 --> 00:09:42,000
software developer and engineer is a

233
00:09:40,260 --> 00:09:43,700
both a blessing and a curse because you

234
00:09:42,000 --> 00:09:46,500
always see someone else's

235
00:09:43,700 --> 00:09:50,279
efforts and go I could do that no I can

236
00:09:46,500 --> 00:09:52,440
do better than that but what happens is

237
00:09:50,279 --> 00:09:53,760
that when you start doing it you realize

238
00:09:52,440 --> 00:09:55,080
there's a reason that there are

239
00:09:53,760 --> 00:09:58,680
companies doing this rather than

240
00:09:55,080 --> 00:10:01,140
individuals because it tends to be a lot

241
00:09:58,680 --> 00:10:03,120
of work to produce a professional device

242
00:10:01,140 --> 00:10:05,040
but anyway I didn't let that stop me so

243
00:10:03,120 --> 00:10:06,480
this is a project I came to talk to you

244
00:10:05,040 --> 00:10:08,720
about that I've been working on and off

245
00:10:06,480 --> 00:10:12,000
on for about a year or so now

246
00:10:08,720 --> 00:10:15,360
in various incarnations so my DIY Groove

247
00:10:12,000 --> 00:10:17,760
box might look a bit like

248
00:10:15,360 --> 00:10:20,040
um yeah a DIY version of those ones but

249
00:10:17,760 --> 00:10:21,360
the main difference is that it's this

250
00:10:20,040 --> 00:10:22,920
thing that you're seeing is not a Groove

251
00:10:21,360 --> 00:10:25,980
box it's what's called a midi controller

252
00:10:22,920 --> 00:10:28,380
it's essentially the equivalent of a

253
00:10:25,980 --> 00:10:30,600
keyboard or a mouse or a touchpad it's

254
00:10:28,380 --> 00:10:32,100
just an input device it does not make

255
00:10:30,600 --> 00:10:35,040
any sound there is no Hardware in there

256
00:10:32,100 --> 00:10:36,899
to make sounds of any sort so hence the

257
00:10:35,040 --> 00:10:39,720
other bit that's in the picture which is

258
00:10:36,899 --> 00:10:42,720
in this case a Raspberry Pi 4 whose job

259
00:10:39,720 --> 00:10:46,380
it is to make the sounds based on the

260
00:10:42,720 --> 00:10:49,079
inputs coming from this controller

261
00:10:46,380 --> 00:10:50,880
so that was my starting point is I

262
00:10:49,079 --> 00:10:52,200
thought well this is pretty much what I

263
00:10:50,880 --> 00:10:54,180
want in terms of the hardware I do not

264
00:10:52,200 --> 00:10:57,060
want to make something and like solder

265
00:10:54,180 --> 00:10:59,579
up a bunch of buttons and encoders and

266
00:10:57,060 --> 00:11:01,260
potentially even a small uh screen so

267
00:10:59,579 --> 00:11:03,839
instead this I chose this is my starting

268
00:11:01,260 --> 00:11:06,540
point which admittedly is a proprietary

269
00:11:03,839 --> 00:11:08,640
like Hardware product but luckily it

270
00:11:06,540 --> 00:11:10,019
uses midi now I've mentioned maybe a

271
00:11:08,640 --> 00:11:11,940
couple of times there's probably people

272
00:11:10,019 --> 00:11:14,100
here who don't know hands up who doesn't

273
00:11:11,940 --> 00:11:16,320
know what midi is or hasn't heard of it

274
00:11:14,100 --> 00:11:18,480
oh actually okay there's not too many

275
00:11:16,320 --> 00:11:19,500
cool so I'll be really quick about this

276
00:11:18,480 --> 00:11:21,060
because I thought I'd have to explain

277
00:11:19,500 --> 00:11:23,399
this I've done this similar talk to

278
00:11:21,060 --> 00:11:25,800
others audiences where midi wasn't a

279
00:11:23,399 --> 00:11:27,120
well-known thing so it's basically both

280
00:11:25,800 --> 00:11:28,680
a protocol and like a hardware

281
00:11:27,120 --> 00:11:31,500
specification but the thing I'm most

282
00:11:28,680 --> 00:11:33,899
involved interested in is it's like a

283
00:11:31,500 --> 00:11:35,880
protocol that these days mostly runs

284
00:11:33,899 --> 00:11:39,420
over USB originally it was over a serial

285
00:11:35,880 --> 00:11:41,279
connection and yes 31 kilobits was the

286
00:11:39,420 --> 00:11:44,880
original speed because it was a nice

287
00:11:41,279 --> 00:11:46,380
mult oh sorry 31.25 because that was a

288
00:11:44,880 --> 00:11:48,180
nice multiple of one megahertz which

289
00:11:46,380 --> 00:11:51,180
which is what most of the equipment was

290
00:11:48,180 --> 00:11:54,240
in the early 80s when midi got started

291
00:11:51,180 --> 00:11:55,680
as like a popular

292
00:11:54,240 --> 00:11:58,560
and I think it's become an industry

293
00:11:55,680 --> 00:12:01,440
standard even though it wasn't quite um

294
00:11:58,560 --> 00:12:03,420
like picked up by any standards body so

295
00:12:01,440 --> 00:12:05,760
luckily for me even though this was a

296
00:12:03,420 --> 00:12:07,920
proprietary device a really nice person

297
00:12:05,760 --> 00:12:10,440
called Paul Curtis had published a set

298
00:12:07,920 --> 00:12:12,180
of Articles a couple of years before me

299
00:12:10,440 --> 00:12:15,000
or a year and a half before me where

300
00:12:12,180 --> 00:12:17,820
titled decoding that kind midi fire uh

301
00:12:15,000 --> 00:12:20,220
implementation where he figured out all

302
00:12:17,820 --> 00:12:23,519
the non-standard midi bits because midi

303
00:12:20,220 --> 00:12:25,019
is made up of both a standard set of

304
00:12:23,519 --> 00:12:27,720
specifications and then there's this

305
00:12:25,019 --> 00:12:29,160
kind of like vendor-specific bit where

306
00:12:27,720 --> 00:12:31,920
vendors can just do whatever the hell

307
00:12:29,160 --> 00:12:35,220
they like sorry for my language so like

308
00:12:31,920 --> 00:12:38,100
unfortunately the acai controller had

309
00:12:35,220 --> 00:12:40,140
some standard bits like say the button

310
00:12:38,100 --> 00:12:41,399
LEDs very simple to figure out like you

311
00:12:40,140 --> 00:12:44,760
could just basically do it with almost

312
00:12:41,399 --> 00:12:47,100
no reference to any documentation and

313
00:12:44,760 --> 00:12:49,380
Illuminating the LEDs was like a little

314
00:12:47,100 --> 00:12:51,360
bit more work to figure out but he did

315
00:12:49,380 --> 00:12:53,279
that really quickly according to his

316
00:12:51,360 --> 00:12:55,019
write-up but then there were things like

317
00:12:53,279 --> 00:12:57,899
figuring out how

318
00:12:55,019 --> 00:13:00,180
those colored pads work and how the

319
00:12:57,899 --> 00:13:02,579
computer can tell the controller to

320
00:13:00,180 --> 00:13:04,320
light up those pads which was very

321
00:13:02,579 --> 00:13:07,500
proprietary very specific to this

322
00:13:04,320 --> 00:13:09,779
controller and note the bit about that

323
00:13:07,500 --> 00:13:11,339
even when he tried to use Wireshark it

324
00:13:09,779 --> 00:13:13,440
couldn't handle like the crazy

325
00:13:11,339 --> 00:13:15,360
non-standard stuff that they did luckily

326
00:13:13,440 --> 00:13:17,579
he did all that work

327
00:13:15,360 --> 00:13:19,440
um to figure that out and so I got to

328
00:13:17,579 --> 00:13:21,180
benefit from it the other thing you may

329
00:13:19,440 --> 00:13:24,480
have noticed with the controller was

330
00:13:21,180 --> 00:13:26,160
that it has an OLED screen a really tiny

331
00:13:24,480 --> 00:13:28,500
like less than one inch screen but

332
00:13:26,160 --> 00:13:30,240
actually up close or like at the normal

333
00:13:28,500 --> 00:13:33,420
operating distance it's actually very

334
00:13:30,240 --> 00:13:37,320
clear like even though it's tiny but it

335
00:13:33,420 --> 00:13:38,459
has a yet even crazier over midi

336
00:13:37,320 --> 00:13:39,899
implementation like for those of you

337
00:13:38,459 --> 00:13:42,240
who've done Electronics you might have

338
00:13:39,899 --> 00:13:44,160
thought it's i2c or it's SBI control

339
00:13:42,240 --> 00:13:45,779
that's how these devices normally are

340
00:13:44,160 --> 00:13:48,600
controlled and internally it probably is

341
00:13:45,779 --> 00:13:50,100
like an i2c device ins with whatever

342
00:13:48,600 --> 00:13:53,220
microcontroller controls this

343
00:13:50,100 --> 00:13:55,320
contraption but externally you talk to

344
00:13:53,220 --> 00:13:57,300
it over midi with this absolute really

345
00:13:55,320 --> 00:13:59,639
crazy mapping that thank God I did not

346
00:13:57,300 --> 00:14:03,720
have to figure out Paul did that for me

347
00:13:59,639 --> 00:14:05,940
and had like published that um mapping

348
00:14:03,720 --> 00:14:09,060
so for all that was left for me was look

349
00:14:05,940 --> 00:14:12,779
at his C code and basically translate

350
00:14:09,060 --> 00:14:14,579
that Matrix into Dart code now use it

351
00:14:12,779 --> 00:14:17,700
even though I'd done this and I got it

352
00:14:14,579 --> 00:14:19,079
working it wasn't super fun to do all

353
00:14:17,700 --> 00:14:21,839
this low-level

354
00:14:19,079 --> 00:14:24,779
um stuff on these days I have done

355
00:14:21,839 --> 00:14:26,940
embedded C long time ago these days I do

356
00:14:24,779 --> 00:14:28,980
like Dart and flutter much more high

357
00:14:26,940 --> 00:14:32,040
level stuff so I quickly package all

358
00:14:28,980 --> 00:14:33,540
this up into some Dart packages like npm

359
00:14:32,040 --> 00:14:35,760
modules for those of you as npm that

360
00:14:33,540 --> 00:14:37,680
sort of thing just into a library that

361
00:14:35,760 --> 00:14:38,880
hid all this away from me so I once I'd

362
00:14:37,680 --> 00:14:41,519
done it I never had to think about it

363
00:14:38,880 --> 00:14:44,040
again and those packages basically

364
00:14:41,519 --> 00:14:45,779
presented me with a much nicer into or

365
00:14:44,040 --> 00:14:47,639
presented me and whoever else is much

366
00:14:45,779 --> 00:14:50,040
nicer interface so for instance you just

367
00:14:47,639 --> 00:14:51,779
get a list sorry for those who don't

368
00:14:50,040 --> 00:14:53,519
know Dart but hopefully this is very C

369
00:14:51,779 --> 00:14:55,440
like you can understand what's happening

370
00:14:53,519 --> 00:14:58,320
here it's just an array of booleans

371
00:14:55,440 --> 00:15:00,839
because that OLED is just monochrome

372
00:14:58,320 --> 00:15:02,519
it's just each pixel is on or off and as

373
00:15:00,839 --> 00:15:05,160
you can see by the sizing it's actually

374
00:15:02,519 --> 00:15:07,320
120 I buy 64 pixels so not exactly high

375
00:15:05,160 --> 00:15:09,180
res so basically it's just an array of

376
00:15:07,320 --> 00:15:11,699
booleans and whichever one's on off

377
00:15:09,180 --> 00:15:15,600
that's how the screen gets lit up

378
00:15:11,699 --> 00:15:17,339
so these are the packages I made that

379
00:15:15,600 --> 00:15:21,300
wrap up

380
00:15:17,339 --> 00:15:25,380
on a Next Level kind of like the more

381
00:15:21,300 --> 00:15:27,600
um everyday bits of uh code that I

382
00:15:25,380 --> 00:15:30,540
needed to draw onto this so doing a font

383
00:15:27,600 --> 00:15:31,980
luckily another old just by sheer

384
00:15:30,540 --> 00:15:35,399
coincidence a really old colleague of

385
00:15:31,980 --> 00:15:37,260
mine Susan Hinton had created a bitmap

386
00:15:35,399 --> 00:15:38,959
font for these devices because she was

387
00:15:37,260 --> 00:15:41,820
mucking around with them using node.js

388
00:15:38,959 --> 00:15:44,399
and I she also had some drawing routines

389
00:15:41,820 --> 00:15:46,740
that I shamelessly pinched and converted

390
00:15:44,399 --> 00:15:49,800
from typescript to Dart and so I had

391
00:15:46,740 --> 00:15:51,779
these more still low level but slightly

392
00:15:49,800 --> 00:15:54,839
higher level API so I could just have

393
00:15:51,779 --> 00:15:56,940
basically something that is a canvas and

394
00:15:54,839 --> 00:15:59,519
you can just do drawing operate you know

395
00:15:56,940 --> 00:16:01,860
the standard draw line draw Square fill

396
00:15:59,519 --> 00:16:03,120
those sort of really basic canvassy

397
00:16:01,860 --> 00:16:05,760
things that people are probably familiar

398
00:16:03,120 --> 00:16:07,500
with lots of different apis like the web

399
00:16:05,760 --> 00:16:09,899
canvas and so forth

400
00:16:07,500 --> 00:16:11,579
okay I've talked about the input and a

401
00:16:09,899 --> 00:16:13,740
little bit of the output but the main

402
00:16:11,579 --> 00:16:15,959
output is sound we want music well

403
00:16:13,740 --> 00:16:19,440
hopefully in my case at least sounds if

404
00:16:15,959 --> 00:16:21,480
not really listenable music now what

405
00:16:19,440 --> 00:16:23,639
people who may have done any kind of

406
00:16:21,480 --> 00:16:25,980
sound programming that required low

407
00:16:23,639 --> 00:16:27,660
latency would realize is it is

408
00:16:25,980 --> 00:16:29,459
absolutely insane to try and do that

409
00:16:27,660 --> 00:16:32,160
with a garbage collected language like

410
00:16:29,459 --> 00:16:33,839
Dart because there's whole papers that

411
00:16:32,160 --> 00:16:35,820
have been written about how crazy it is

412
00:16:33,839 --> 00:16:39,660
to even use Malik for those of you who

413
00:16:35,820 --> 00:16:42,240
are C literate to allocate memory while

414
00:16:39,660 --> 00:16:44,639
you're in the time-sensitive bit of the

415
00:16:42,240 --> 00:16:46,199
code that actually is pushing audio data

416
00:16:44,639 --> 00:16:47,459
out to the sound card when you're doing

417
00:16:46,199 --> 00:16:49,380
low latency like it doesn't matter if

418
00:16:47,459 --> 00:16:51,720
you're playing back an mp4 or something

419
00:16:49,380 --> 00:16:53,699
like that's not low latency low latency

420
00:16:51,720 --> 00:16:54,959
is when you're pressing a key and you

421
00:16:53,699 --> 00:16:56,699
want the sound to come out as fast as

422
00:16:54,959 --> 00:16:58,800
possible out of the speaker not when

423
00:16:56,699 --> 00:17:00,959
you're like listening to us like a music

424
00:16:58,800 --> 00:17:02,699
track or watching a video so for that

425
00:17:00,959 --> 00:17:04,439
sort of thing a garbage collected

426
00:17:02,699 --> 00:17:06,360
language is no good like even like I

427
00:17:04,439 --> 00:17:08,280
said they people tell you not to do

428
00:17:06,360 --> 00:17:10,860
memory allocations on the thread that's

429
00:17:08,280 --> 00:17:14,339
doing that because the Malik might

430
00:17:10,860 --> 00:17:16,799
potentially take too long so this was

431
00:17:14,339 --> 00:17:19,559
yeah using Dart was no go so what could

432
00:17:16,799 --> 00:17:22,140
I do well I shopped around for different

433
00:17:19,559 --> 00:17:25,140
ways of getting sand out and I settled

434
00:17:22,140 --> 00:17:27,059
on this which was a thing called sunvox

435
00:17:25,140 --> 00:17:29,340
sunvox is

436
00:17:27,059 --> 00:17:33,660
again like a niche within the niche it's

437
00:17:29,340 --> 00:17:35,280
a small fast and Powerful modular

438
00:17:33,660 --> 00:17:38,640
synthesizer with a pattern-based

439
00:17:35,280 --> 00:17:40,679
sequencer brackets tracker so it also

440
00:17:38,640 --> 00:17:44,460
comes luckily for me in a library

441
00:17:40,679 --> 00:17:47,580
version because sunbox itself is not

442
00:17:44,460 --> 00:17:50,940
um open source it's like a free or

443
00:17:47,580 --> 00:17:54,419
slightly paid for product

444
00:17:50,940 --> 00:17:57,360
but it had it's Core Audio library is an

445
00:17:54,419 --> 00:17:59,580
MIT licensed open source Library

446
00:17:57,360 --> 00:18:02,280
perfect for what I needed I just wanted

447
00:17:59,580 --> 00:18:06,240
the sound bit I did not want

448
00:18:02,280 --> 00:18:07,860
um a full basically audio package now a

449
00:18:06,240 --> 00:18:11,400
little tangent because of those brackets

450
00:18:07,860 --> 00:18:13,320
tracker what is a tracker for those of

451
00:18:11,400 --> 00:18:15,360
you who had a misspent youth like me in

452
00:18:13,320 --> 00:18:17,460
the 80s might have heard of trackers

453
00:18:15,360 --> 00:18:18,900
because they were often used to it was

454
00:18:17,460 --> 00:18:21,000
the software that was used to produce

455
00:18:18,900 --> 00:18:22,980
the audio tracks that played when you

456
00:18:21,000 --> 00:18:25,799
applied the crack on your favorite game

457
00:18:22,980 --> 00:18:28,320
that you did not legally purchase and

458
00:18:25,799 --> 00:18:30,600
hence did not have the whatever DRM was

459
00:18:28,320 --> 00:18:33,600
trying to protect and so this was the

460
00:18:30,600 --> 00:18:35,640
days like we're talking 80s like days of

461
00:18:33,600 --> 00:18:38,039
the 16-bit computers like the Amiga 500s

462
00:18:35,640 --> 00:18:39,780
trackers became very popular they

463
00:18:38,039 --> 00:18:42,299
basically preceded these digital audio

464
00:18:39,780 --> 00:18:45,179
workstations that are now the mainstream

465
00:18:42,299 --> 00:18:48,840
way of making electronic music

466
00:18:45,179 --> 00:18:50,520
so the track is like gradually died away

467
00:18:48,840 --> 00:18:52,860
on computers like they're still used

468
00:18:50,520 --> 00:18:55,679
like in um some places like the demo

469
00:18:52,860 --> 00:18:58,080
scene but what's happened strangely to

470
00:18:55,679 --> 00:18:59,640
me recently that I've discovered it is

471
00:18:58,080 --> 00:19:01,620
that there's been a Resurgence in

472
00:18:59,640 --> 00:19:04,080
interest based on Hardware trackers so

473
00:19:01,620 --> 00:19:06,059
these are coming back again to my

474
00:19:04,080 --> 00:19:07,620
original kind of topic these are like

475
00:19:06,059 --> 00:19:10,080
standard these Standalone groovebox

476
00:19:07,620 --> 00:19:12,720
devices but now done in the format of

477
00:19:10,080 --> 00:19:14,880
trackers now what I guess the key thing

478
00:19:12,720 --> 00:19:17,039
about trackers is that they have this

479
00:19:14,880 --> 00:19:19,860
grid like people call a spreadsheet

480
00:19:17,039 --> 00:19:21,840
Excel like way of laying out the tracks

481
00:19:19,860 --> 00:19:23,880
unlike digital audio stations which

482
00:19:21,840 --> 00:19:25,320
usually look like more a piano roll for

483
00:19:23,880 --> 00:19:27,780
those of you who are musically in kind

484
00:19:25,320 --> 00:19:31,620
UI

485
00:19:27,780 --> 00:19:33,660
so for me sandbox like was perfect

486
00:19:31,620 --> 00:19:36,179
because it was a really as you can see

487
00:19:33,660 --> 00:19:38,340
mature long-term project it's been

488
00:19:36,179 --> 00:19:39,600
around so long that it had a palm OS

489
00:19:38,340 --> 00:19:42,120
version

490
00:19:39,600 --> 00:19:43,620
but also meant that it was super that

491
00:19:42,120 --> 00:19:45,780
meant it was super lightweight if it ran

492
00:19:43,620 --> 00:19:47,520
on Palm OS even like back in the day

493
00:19:45,780 --> 00:19:48,660
that meant if I wanted something that

494
00:19:47,520 --> 00:19:50,220
was going to run low power at

495
00:19:48,660 --> 00:19:51,840
singleboard computer like a Raspberry Pi

496
00:19:50,220 --> 00:19:53,220
and my intention isn't to use a

497
00:19:51,840 --> 00:19:55,559
Raspberry Pi 4 in the end but something

498
00:19:53,220 --> 00:19:58,440
much more low powered this is just a

499
00:19:55,559 --> 00:20:00,539
convenient prototyping device this

500
00:19:58,440 --> 00:20:02,820
looked like a gold mine this looked like

501
00:20:00,539 --> 00:20:04,860
the thing I wanted thankfully it's

502
00:20:02,820 --> 00:20:07,020
maintained an author it's still been

503
00:20:04,860 --> 00:20:09,840
going at it for like over 10 years or

504
00:20:07,020 --> 00:20:12,120
maybe close to 15 years now so it looks

505
00:20:09,840 --> 00:20:14,820
like it's not going away anytime soon so

506
00:20:12,120 --> 00:20:17,220
like I said the sunvox app itself has a

507
00:20:14,820 --> 00:20:20,039
UI like this I don't want any of that UI

508
00:20:17,220 --> 00:20:22,260
that is the thing that I'm not trying to

509
00:20:20,039 --> 00:20:26,220
do I am trying to build a hardware

510
00:20:22,260 --> 00:20:28,620
device so instead I've got a lightweight

511
00:20:26,220 --> 00:20:31,200
library that lets me put out the sound

512
00:20:28,620 --> 00:20:32,280
its source is available there's if I

513
00:20:31,200 --> 00:20:35,100
have time there's a little bit of a

514
00:20:32,280 --> 00:20:36,840
complicated story about how open source

515
00:20:35,100 --> 00:20:39,059
open source

516
00:20:36,840 --> 00:20:40,860
um lib sandbox is but anyway it's open

517
00:20:39,059 --> 00:20:43,980
source enough

518
00:20:40,860 --> 00:20:46,620
um and so basically all I need to do is

519
00:20:43,980 --> 00:20:49,380
a way to call it from Dart nice thing is

520
00:20:46,620 --> 00:20:54,120
Dart has and I'm going to like put on my

521
00:20:49,380 --> 00:20:56,880
Dart Advocate hat here Dart to me has a

522
00:20:54,120 --> 00:20:59,340
beautiful ffi that's a foreign function

523
00:20:56,880 --> 00:21:02,039
interface for those of you who haven't

524
00:20:59,340 --> 00:21:03,720
needed to call basically

525
00:21:02,039 --> 00:21:06,059
um one language from another language so

526
00:21:03,720 --> 00:21:09,000
in this case it's a way of calling any

527
00:21:06,059 --> 00:21:10,559
basically any c code NEC library from

528
00:21:09,000 --> 00:21:13,080
Dart

529
00:21:10,559 --> 00:21:15,600
and what it means is that I have

530
00:21:13,080 --> 00:21:17,520
basically in Fairly non-technical terms

531
00:21:15,600 --> 00:21:19,559
it has it gives me a really easy and

532
00:21:17,520 --> 00:21:21,539
clean way of making use of a C library

533
00:21:19,559 --> 00:21:23,880
which is what lib sandbox is from my

534
00:21:21,539 --> 00:21:25,620
Dart code which is no good for

535
00:21:23,880 --> 00:21:28,500
generating the audio itself so live

536
00:21:25,620 --> 00:21:30,840
sunbox does all the audio playback in

537
00:21:28,500 --> 00:21:33,120
generation for me Dart is kind of like

538
00:21:30,840 --> 00:21:36,419
the Puppet Master it just sends things

539
00:21:33,120 --> 00:21:37,919
like play or go to this point in time or

540
00:21:36,419 --> 00:21:40,140
stop or pause that sort of thing or

541
00:21:37,919 --> 00:21:42,000
switch tracks or mute tracks so it's

542
00:21:40,140 --> 00:21:43,440
just like the control system as you like

543
00:21:42,000 --> 00:21:45,000
so it gives me a nice high level

544
00:21:43,440 --> 00:21:47,539
language to do all my control stuff in

545
00:21:45,000 --> 00:21:50,640
lib sandbox does all the low level

546
00:21:47,539 --> 00:21:53,580
nitty-gritty audio uh

547
00:21:50,640 --> 00:21:54,900
playback and synthesis for me and so

548
00:21:53,580 --> 00:21:56,820
that's one thing I probably should say

549
00:21:54,900 --> 00:21:59,880
when I say the word synthesis I said

550
00:21:56,820 --> 00:22:01,460
mentioned synthesizers and Samplers a

551
00:21:59,880 --> 00:22:05,240
little while ago so basically

552
00:22:01,460 --> 00:22:08,159
synthesizers use raw sine square

553
00:22:05,240 --> 00:22:09,600
triangle waves to create audio or

554
00:22:08,159 --> 00:22:11,640
another technique called frequency

555
00:22:09,600 --> 00:22:13,200
modulation Samplers Play Back Little

556
00:22:11,640 --> 00:22:15,480
Bits so you might have a recording of a

557
00:22:13,200 --> 00:22:18,120
piano recording of a snare drum kick

558
00:22:15,480 --> 00:22:22,620
drums some guitar and just use those

559
00:22:18,120 --> 00:22:24,720
little Snippets of audio and sometimes

560
00:22:22,620 --> 00:22:26,460
Tunes them up and down to get the notes

561
00:22:24,720 --> 00:22:29,059
and so those are kind of like the two

562
00:22:26,460 --> 00:22:33,120
main ways these instruments generate

563
00:22:29,059 --> 00:22:34,980
musical sounding sounds so the track is

564
00:22:33,120 --> 00:22:37,679
in bygone days we're all Samplers

565
00:22:34,980 --> 00:22:39,720
because all those computers had really

566
00:22:37,679 --> 00:22:41,880
minimal CPU power these days we've got

567
00:22:39,720 --> 00:22:44,880
huge amount of CPU power in our phones

568
00:22:41,880 --> 00:22:46,260
let alone on our laptops and desktops so

569
00:22:44,880 --> 00:22:49,200
synthesis

570
00:22:46,260 --> 00:22:51,720
um is quite feasible in terms of a

571
00:22:49,200 --> 00:22:53,460
modern tracker and so sunbox does both

572
00:22:51,720 --> 00:22:55,500
it lets you play back samples but it

573
00:22:53,460 --> 00:22:57,299
also that's the where the modular bit

574
00:22:55,500 --> 00:22:59,880
comes in this description it's kind of

575
00:22:57,299 --> 00:23:01,200
gives you all these little modules that

576
00:22:59,880 --> 00:23:02,940
generate different types of sounds

577
00:23:01,200 --> 00:23:05,940
different types of waves that you can

578
00:23:02,940 --> 00:23:09,360
stick together apply effects to and get

579
00:23:05,940 --> 00:23:11,159
all these different kinds of musical

580
00:23:09,360 --> 00:23:14,700
outputs

581
00:23:11,159 --> 00:23:17,340
so having that basically I need to get

582
00:23:14,700 --> 00:23:20,520
back to my core goal which is getting

583
00:23:17,340 --> 00:23:22,500
something running on a device so the

584
00:23:20,520 --> 00:23:25,559
idea is has to run on something like a

585
00:23:22,500 --> 00:23:27,960
pi because I want to put a singleboard

586
00:23:25,559 --> 00:23:29,400
computer Plus Battery into that

587
00:23:27,960 --> 00:23:31,320
um

588
00:23:29,400 --> 00:23:32,760
acai controller's case and have

589
00:23:31,320 --> 00:23:34,500
something that's reasonably Standalone

590
00:23:32,760 --> 00:23:36,960
like those group Standalone Groove boxes

591
00:23:34,500 --> 00:23:39,240
they're like usually battery powered

592
00:23:36,960 --> 00:23:39,960
Standalone devices like the like this

593
00:23:39,240 --> 00:23:42,059
one

594
00:23:39,960 --> 00:23:44,039
that I showed you see no cables it's

595
00:23:42,059 --> 00:23:46,260
just running off an internal battery and

596
00:23:44,039 --> 00:23:48,539
it's fairly lightweight not too thick

597
00:23:46,260 --> 00:23:50,039
that's kind of like the end goal so I

598
00:23:48,539 --> 00:23:53,039
need something

599
00:23:50,039 --> 00:23:54,840
that is low powered enough probably low

600
00:23:53,039 --> 00:23:57,059
power than the Raspberry Pi 4 that is

601
00:23:54,840 --> 00:23:59,280
going to fit in my MIDI controller case

602
00:23:57,059 --> 00:24:02,039
long along with a battery

603
00:23:59,280 --> 00:24:04,020
so basically these are the steps I took

604
00:24:02,039 --> 00:24:05,520
to get sunbox running on the Raspberry

605
00:24:04,020 --> 00:24:07,260
Pi

606
00:24:05,520 --> 00:24:08,460
fairly straightforward like you just

607
00:24:07,260 --> 00:24:11,159
basically

608
00:24:08,460 --> 00:24:12,299
needed to compile the doc code sorry I

609
00:24:11,159 --> 00:24:14,039
should have said for those who aren't

610
00:24:12,299 --> 00:24:15,780
familiar with dart Dart has an option to

611
00:24:14,039 --> 00:24:17,100
compile to Native binary so it's not

612
00:24:15,780 --> 00:24:19,260
like say JavaScript where you have to

613
00:24:17,100 --> 00:24:21,840
have the JavaScript runtime engine

614
00:24:19,260 --> 00:24:23,700
interpret or just in time compiling the

615
00:24:21,840 --> 00:24:25,559
code when it runs what you can do with

616
00:24:23,700 --> 00:24:27,419
dart is you can actually compile a

617
00:24:25,559 --> 00:24:28,919
standalone executable Standalone is and

618
00:24:27,419 --> 00:24:31,679
the only thing it links to is the C

619
00:24:28,919 --> 00:24:33,659
library everything else is bundled in

620
00:24:31,679 --> 00:24:37,380
that executable file and you can now put

621
00:24:33,659 --> 00:24:41,340
that on like Windows Mac OS iOS Android

622
00:24:37,380 --> 00:24:44,640
and for me Linux and arm Linux as well

623
00:24:41,340 --> 00:24:46,380
so there's like x86 and um support so

624
00:24:44,640 --> 00:24:49,260
thankfully I can do both

625
00:24:46,380 --> 00:24:51,480
and actually risk 5 support coming which

626
00:24:49,260 --> 00:24:53,820
is what my kind of final Target is but

627
00:24:51,480 --> 00:24:57,000
more on that in the SEC

628
00:24:53,820 --> 00:25:00,480
so basically I had a

629
00:24:57,000 --> 00:25:03,419
compiled XZ Link in my case it actually

630
00:25:00,480 --> 00:25:05,820
does like at runtime link to the sandbox

631
00:25:03,419 --> 00:25:07,440
library because I need that so it's not

632
00:25:05,820 --> 00:25:10,640
completely Standalone but close enough

633
00:25:07,440 --> 00:25:13,559
and then I just put it into

634
00:25:10,640 --> 00:25:14,820
etc.rc.local to start up on boot and

635
00:25:13,559 --> 00:25:17,100
essentially there we go I've got a

636
00:25:14,820 --> 00:25:20,580
standalone Hardware device if not in a

637
00:25:17,100 --> 00:25:23,400
commercially viable form factor

638
00:25:20,580 --> 00:25:25,020
um like I said a moment ago even though

639
00:25:23,400 --> 00:25:27,960
I'm using arm I think I need something

640
00:25:25,020 --> 00:25:30,779
Lop out and the current crop of risk

641
00:25:27,960 --> 00:25:34,380
five boards are very immature and very

642
00:25:30,779 --> 00:25:38,340
new but luckily are already supported by

643
00:25:34,380 --> 00:25:40,559
Dart so I can run my dark compiled Dart

644
00:25:38,340 --> 00:25:42,179
code on them and more importantly

645
00:25:40,559 --> 00:25:43,980
they're they're significantly lower

646
00:25:42,179 --> 00:25:46,740
powered than say the Raspberry Pi 4 but

647
00:25:43,980 --> 00:25:50,100
yet powerful enough that they can cope

648
00:25:46,740 --> 00:25:51,659
with running sunbox so essentially I

649
00:25:50,100 --> 00:25:54,120
think I've got something that's going to

650
00:25:51,659 --> 00:25:55,440
be a viable proposition to put into a

651
00:25:54,120 --> 00:25:57,659
case so maybe next year I can come back

652
00:25:55,440 --> 00:26:00,419
and actually show you a fully built

653
00:25:57,659 --> 00:26:02,340
Standalone device and not just my

654
00:26:00,419 --> 00:26:04,380
jewelry rig prototype

655
00:26:02,340 --> 00:26:07,080
so with that hopefully I've got enough

656
00:26:04,380 --> 00:26:09,539
time for a very quick demo

657
00:26:07,080 --> 00:26:14,480
um I'm just going to

658
00:26:09,539 --> 00:26:14,480
run oops oh for good mistakes

659
00:26:15,960 --> 00:26:20,059
yep

660
00:26:17,640 --> 00:26:20,059
sorry

661
00:26:21,360 --> 00:26:28,820
I was going to try and run a webcam if I

662
00:26:25,860 --> 00:26:28,820
click on the right button

663
00:26:30,059 --> 00:26:35,400
so here's the device running here now

664
00:26:32,640 --> 00:26:37,799
unfortunately my cable is a little bit

665
00:26:35,400 --> 00:26:40,620
audio cable I've just found out is a

666
00:26:37,799 --> 00:26:42,600
little bit wonky so we may not get sound

667
00:26:40,620 --> 00:26:45,120
but basically I just wanted to quickly

668
00:26:42,600 --> 00:26:47,940
show you where the into where where I'm

669
00:26:45,120 --> 00:26:50,580
up to at the moment with interface so I

670
00:26:47,940 --> 00:26:53,640
have the beginnings of a display for

671
00:26:50,580 --> 00:26:55,140
this sequencer for the steps but it's

672
00:26:53,640 --> 00:26:57,000
very rudimentary so I'm going to skip

673
00:26:55,140 --> 00:26:58,860
that right now because that's literally

674
00:26:57,000 --> 00:27:01,679
the work in progress at the moment what

675
00:26:58,860 --> 00:27:04,200
I also have though is essentially a

676
00:27:01,679 --> 00:27:07,020
chromatic keyboard I'm sorry the res the

677
00:27:04,200 --> 00:27:08,580
contrast isn't great but hopefully if I

678
00:27:07,020 --> 00:27:10,020
I think it's small enough room that I

679
00:27:08,580 --> 00:27:13,200
can hold up and show you like

680
00:27:10,020 --> 00:27:15,059
essentially the white keys the blue keys

681
00:27:13,200 --> 00:27:18,779
are The Black Keys because black doesn't

682
00:27:15,059 --> 00:27:20,820
go so well with a RGB LEDs so this is

683
00:27:18,779 --> 00:27:23,220
hopefully something that looks like a

684
00:27:20,820 --> 00:27:25,799
piano keyboard or chromatic keyboard for

685
00:27:23,220 --> 00:27:27,539
those who play or who know their scales

686
00:27:25,799 --> 00:27:29,400
and oh actually what I'm doing it I

687
00:27:27,539 --> 00:27:32,880
might as well show it like this as well

688
00:27:29,400 --> 00:27:34,740
these colored Keys here you can see

689
00:27:32,880 --> 00:27:35,960
they're much more nicely colored than in

690
00:27:34,740 --> 00:27:38,100
the video feed

691
00:27:35,960 --> 00:27:39,840
represent the different instruments that

692
00:27:38,100 --> 00:27:42,539
are available in this sandbox project

693
00:27:39,840 --> 00:27:45,720
file so

694
00:27:42,539 --> 00:27:47,400
if I go back to uh this view that

695
00:27:45,720 --> 00:27:49,919
finally there's also another view here

696
00:27:47,400 --> 00:27:52,140
where it shows all the

697
00:27:49,919 --> 00:27:54,779
modules not just the instruments but all

698
00:27:52,140 --> 00:27:56,820
the effects modules and everything I

699
00:27:54,779 --> 00:27:59,700
hopefully can make maybe move the camera

700
00:27:56,820 --> 00:28:01,440
a bit closer and show you on the LED so

701
00:27:59,700 --> 00:28:04,679
that's the Distortion module there's a

702
00:28:01,440 --> 00:28:08,100
flanger echo guitar

703
00:28:04,679 --> 00:28:09,360
oh no okay it it should be playing back

704
00:28:08,100 --> 00:28:11,400
the audio unfortunately I think I've

705
00:28:09,360 --> 00:28:12,600
wiggled the cable and it's not playing

706
00:28:11,400 --> 00:28:14,039
back at the moment I'll see if I can

707
00:28:12,600 --> 00:28:16,200
wiggle it some more and get it to play

708
00:28:14,039 --> 00:28:19,500
back shortly but basically that gives

709
00:28:16,200 --> 00:28:22,080
you a preview of the sound and

710
00:28:19,500 --> 00:28:24,799
you can also see like oops I will put

711
00:28:22,080 --> 00:28:24,799
this back here

712
00:28:25,340 --> 00:28:30,600
with the shift function what I've also

713
00:28:27,600 --> 00:28:32,580
added is displaying which things are

714
00:28:30,600 --> 00:28:34,140
connected to Watts so you can see these

715
00:28:32,580 --> 00:28:37,440
light up saying that they're connected

716
00:28:34,140 --> 00:28:39,600
which is oops sorry which is for

717
00:28:37,440 --> 00:28:42,779
instance here oh it's not very well

718
00:28:39,600 --> 00:28:44,880
focused but it says Reverb

719
00:28:42,779 --> 00:28:46,860
connected to the Reverb to connected to

720
00:28:44,880 --> 00:28:49,380
the compressor so that's basically kind

721
00:28:46,860 --> 00:28:50,760
of like the the modular part of sunbox

722
00:28:49,380 --> 00:28:53,100
where it lets you connect all these

723
00:28:50,760 --> 00:28:55,340
different modules that do sound or sound

724
00:28:53,100 --> 00:28:57,779
effects and interconnect them together

725
00:28:55,340 --> 00:29:00,659
there's a niche within the niche again

726
00:28:57,779 --> 00:29:02,279
called eurorack which lets people create

727
00:29:00,659 --> 00:29:03,779
all these Hardware modules and to

728
00:29:02,279 --> 00:29:06,779
connect them with wires and essentially

729
00:29:03,779 --> 00:29:09,779
this is the software version of that

730
00:29:06,779 --> 00:29:12,260
um likewise I do have playback simple

731
00:29:09,779 --> 00:29:15,059
playback like in terms of play pause

732
00:29:12,260 --> 00:29:17,100
and stop so I'm just going to try and

733
00:29:15,059 --> 00:29:19,919
play it and I'll wiggle the cable to see

734
00:29:17,100 --> 00:29:24,000
if I can get audio happening but

735
00:29:19,919 --> 00:29:27,720
if not I can direct you to a video demo

736
00:29:24,000 --> 00:29:28,399
I have on my YouTube account with

737
00:29:27,720 --> 00:29:30,919
um

738
00:29:28,399 --> 00:29:34,500
this basically the same thing actually

739
00:29:30,919 --> 00:29:38,700
connected to a working audio cable

740
00:29:34,500 --> 00:29:40,500
but oh it's very Dodge so I might not be

741
00:29:38,700 --> 00:29:42,240
able to get it working so I might just

742
00:29:40,500 --> 00:29:43,860
leave it there and see if I can get it

743
00:29:42,240 --> 00:29:45,600
working in case if there's any time for

744
00:29:43,860 --> 00:29:48,779
questions while I have field questions

745
00:29:45,600 --> 00:29:50,980
and wiggle with it so with that thank

746
00:29:48,779 --> 00:29:57,710
you very much for your time

747
00:29:50,980 --> 00:29:57,710
[Applause]

748
00:29:59,700 --> 00:30:06,419
so sorry

749
00:30:01,740 --> 00:30:08,700
um yeah do we have questions for maxim

750
00:30:06,419 --> 00:30:11,299
all right stencil oh yeah oh there's one

751
00:30:08,700 --> 00:30:11,299
okay

752
00:30:16,140 --> 00:30:22,620
thanks very much for that

753
00:30:18,299 --> 00:30:25,679
um I guess my first sort of thought

754
00:30:22,620 --> 00:30:27,919
there is if you've got a midi cable or a

755
00:30:25,679 --> 00:30:30,779
USB cable pretending to be a midi cable

756
00:30:27,919 --> 00:30:32,880
between the computer and the the

757
00:30:30,779 --> 00:30:35,760
keyboard then

758
00:30:32,880 --> 00:30:39,380
do you need to have like you know

759
00:30:35,760 --> 00:30:41,580
you don't at that point need to have the

760
00:30:39,380 --> 00:30:45,419
Raspberry Pi or whatever's doing your

761
00:30:41,580 --> 00:30:46,799
audio right next to the fire board so it

762
00:30:45,419 --> 00:30:49,620
could actually be separate couldn't it

763
00:30:46,799 --> 00:30:50,880
yes yeah so it's like there's no

764
00:30:49,620 --> 00:30:53,880
restriction to have them all together

765
00:30:50,880 --> 00:30:55,860
they can be like separated by meters and

766
00:30:53,880 --> 00:30:57,659
in fact like that's what a lot of actual

767
00:30:55,860 --> 00:31:00,179
musicians who actually perform in front

768
00:30:57,659 --> 00:31:02,159
of people uh do is that they'll have a

769
00:31:00,179 --> 00:31:05,460
bank of midi controllers connected to

770
00:31:02,159 --> 00:31:08,279
say a laptop that's like off to the side

771
00:31:05,460 --> 00:31:10,440
or somewhere or also done by DJs as well

772
00:31:08,279 --> 00:31:13,140
who these days often have basically

773
00:31:10,440 --> 00:31:16,559
electronic control decks and there can

774
00:31:13,140 --> 00:31:18,779
actually just tied via USB to like a Mac

775
00:31:16,559 --> 00:31:20,460
or something that's like kind of behind

776
00:31:18,779 --> 00:31:24,779
the scenes and they're just doing all

777
00:31:20,460 --> 00:31:27,240
their controls via the midi controllers

778
00:31:24,779 --> 00:31:28,380
even like yeah even DJ kind of

779
00:31:27,240 --> 00:31:30,840
scratching stuff and everything that's

780
00:31:28,380 --> 00:31:32,520
all available as midi controllers these

781
00:31:30,840 --> 00:31:34,020
days so yeah there's no reason why I

782
00:31:32,520 --> 00:31:35,460
have to be together I only put them

783
00:31:34,020 --> 00:31:37,559
together because like I said I wanted

784
00:31:35,460 --> 00:31:39,840
like a standalone portable device just

785
00:31:37,559 --> 00:31:40,559
like I guess the

786
00:31:39,840 --> 00:31:43,260
um

787
00:31:40,559 --> 00:31:44,820
the commercial manufacturers do and so

788
00:31:43,260 --> 00:31:46,500
that was my original idea was to have

789
00:31:44,820 --> 00:31:49,620
something where I can get it all into

790
00:31:46,500 --> 00:31:51,360
this case all into this one case and

791
00:31:49,620 --> 00:31:52,919
it's not very thick so but it should fit

792
00:31:51,360 --> 00:31:55,020
like basically a single board there's

793
00:31:52,919 --> 00:31:57,299
plenty of room inside I've opened it up

794
00:31:55,020 --> 00:31:59,940
um enough enough anyway to fit in like a

795
00:31:57,299 --> 00:32:02,760
small uh singleboard computer and a

796
00:31:59,940 --> 00:32:05,460
smallish like USB battery and just like

797
00:32:02,760 --> 00:32:07,919
a little bit of DIY USB wiring to hook

798
00:32:05,460 --> 00:32:10,140
them all together inside with a tiny uh

799
00:32:07,919 --> 00:32:15,380
hub

800
00:32:10,140 --> 00:32:15,380
yes okay we have another question here

801
00:32:18,419 --> 00:32:22,740
I was just curious what the risk five

802
00:32:21,000 --> 00:32:25,559
board was that you had up earlier it

803
00:32:22,740 --> 00:32:28,320
looked like a cyped or sipped yes oh

804
00:32:25,559 --> 00:32:30,120
okay very very sharp eyes yes it was a

805
00:32:28,320 --> 00:32:32,340
cyped lychee

806
00:32:30,120 --> 00:32:35,159
um RV or

807
00:32:32,340 --> 00:32:37,559
um RV dock which uses like the D1 or

808
00:32:35,159 --> 00:32:40,500
winner D1 risk five

809
00:32:37,559 --> 00:32:42,539
um microcontroller that's become

810
00:32:40,500 --> 00:32:44,159
actually one thing I didn't mention was

811
00:32:42,539 --> 00:32:46,200
the fact that you can't actually get

812
00:32:44,159 --> 00:32:48,899
Raspberry Pi's at the moment unless you

813
00:32:46,200 --> 00:32:52,500
pay scalper prices as in more than Rock

814
00:32:48,899 --> 00:32:54,659
ticket Rock concert prices whereas the D

815
00:32:52,500 --> 00:32:57,480
the risk ships amazingly even though

816
00:32:54,659 --> 00:32:59,159
they're so new are actually available at

817
00:32:57,480 --> 00:33:01,620
least in small quantity like amp

818
00:32:59,159 --> 00:33:05,940
hobbyist quantities whereas buying even

819
00:33:01,620 --> 00:33:10,559
one or two raspberry pies I think I saw

820
00:33:05,940 --> 00:33:12,360
uh 220 Australian dollars for one on um

821
00:33:10,559 --> 00:33:15,659
eBay a little while ago whereas these

822
00:33:12,360 --> 00:33:17,039
things are I think 20 US dollars so like

823
00:33:15,659 --> 00:33:19,860
they're actually available so not only

824
00:33:17,039 --> 00:33:22,260
are they a good fit for my my use case

825
00:33:19,860 --> 00:33:23,640
in terms of Hardware profile but they're

826
00:33:22,260 --> 00:33:26,419
actually obtainable at the moment unlike

827
00:33:23,640 --> 00:33:26,419
Raspberry Pi's

828
00:33:26,460 --> 00:33:30,480
a great session maximum thanks and cool

829
00:33:29,039 --> 00:33:32,220
project I'm just curious if you could

830
00:33:30,480 --> 00:33:34,380
comment as I understand it with the

831
00:33:32,220 --> 00:33:35,519
commercial offerings equivalent to this

832
00:33:34,380 --> 00:33:36,840
a lot of what you get is all the

833
00:33:35,519 --> 00:33:38,279
different sample libraries and sounds

834
00:33:36,840 --> 00:33:40,799
could you comment a little on what's

835
00:33:38,279 --> 00:33:42,360
available Libre wise or the ability to

836
00:33:40,799 --> 00:33:45,240
import other sound libraries and sounds

837
00:33:42,360 --> 00:33:48,659
perhaps please yeah there's a huge

838
00:33:45,240 --> 00:33:51,299
college industry in Sample libraries

839
00:33:48,659 --> 00:33:53,460
some are free some are paid there's a

840
00:33:51,299 --> 00:33:54,720
lot of actually YouTubers who kind of

841
00:33:53,460 --> 00:33:58,200
like try and make a name for themselves

842
00:33:54,720 --> 00:34:00,120
by releasing either free or like uh very

843
00:33:58,200 --> 00:34:03,360
cheap like sample libraries like for a

844
00:34:00,120 --> 00:34:05,820
few dollars so um yeah I could uh and of

845
00:34:03,360 --> 00:34:07,860
course there's complete sites like free

846
00:34:05,820 --> 00:34:09,839
sound I think dot org free sound

847
00:34:07,860 --> 00:34:12,780
archive.org where there's like literally

848
00:34:09,839 --> 00:34:15,980
millions of sounds available or samples

849
00:34:12,780 --> 00:34:18,480
available under fairly liberal licenses

850
00:34:15,980 --> 00:34:21,480
but actually what I should say is that

851
00:34:18,480 --> 00:34:24,359
most of these devices do not come with

852
00:34:21,480 --> 00:34:25,800
sample libraries a few do like as kind

853
00:34:24,359 --> 00:34:28,320
of like the manufacturers will bundle

854
00:34:25,800 --> 00:34:32,220
stuff but for the most part it's left to

855
00:34:28,320 --> 00:34:33,899
the owner to buy sample packs themselves

856
00:34:32,220 --> 00:34:36,240
and some people have like literally

857
00:34:33,899 --> 00:34:38,040
gigabytes of samples like I complain

858
00:34:36,240 --> 00:34:40,679
that they're whatever device they get oh

859
00:34:38,040 --> 00:34:42,659
it's only got like you know X number of

860
00:34:40,679 --> 00:34:45,240
gig storage I can't fit my whole sample

861
00:34:42,659 --> 00:34:48,260
library on this one actually takes

862
00:34:45,240 --> 00:34:50,820
um SD cards up to 32 gig and I have seen

863
00:34:48,260 --> 00:34:52,080
people complaining that oh I think

864
00:34:50,820 --> 00:34:54,859
that's going to be a bit too limiting

865
00:34:52,080 --> 00:34:54,859
for me and

866
00:34:56,280 --> 00:35:01,320
and so like yeah that um

867
00:34:59,099 --> 00:35:03,180
that that is actually was one of the

868
00:35:01,320 --> 00:35:05,880
things that surprised me is like I guess

869
00:35:03,180 --> 00:35:08,460
there's a bit of a I wouldn't say Magpie

870
00:35:05,880 --> 00:35:09,839
approach but uh there's definitely

871
00:35:08,460 --> 00:35:12,359
people who have huge Collections and I

872
00:35:09,839 --> 00:35:14,940
have to admit that I have fallen prey to

873
00:35:12,359 --> 00:35:17,700
that like I already have probably a

874
00:35:14,940 --> 00:35:19,619
couple of gig of just yeah

875
00:35:17,700 --> 00:35:21,300
um sample pack libraries that I've just

876
00:35:19,619 --> 00:35:25,079
spotted along the way and I've probably

877
00:35:21,300 --> 00:35:27,119
spent like either 15 or 20 all up and

878
00:35:25,079 --> 00:35:28,859
just for the purchased ones and the rest

879
00:35:27,119 --> 00:35:30,839
were free so

880
00:35:28,859 --> 00:35:32,880
um there's so much

881
00:35:30,839 --> 00:35:34,619
um free or very cheap sample libraries

882
00:35:32,880 --> 00:35:36,420
out there that I think

883
00:35:34,619 --> 00:35:39,599
um if you are into sample based music

884
00:35:36,420 --> 00:35:43,280
it's really I guess a golden age in

885
00:35:39,599 --> 00:35:43,280
terms of making musical samples

886
00:35:44,520 --> 00:35:48,660
I have a question for you Matt oh sure

887
00:35:46,800 --> 00:35:52,260
I'm just wondering

888
00:35:48,660 --> 00:35:55,920
um because I too am not very good at

889
00:35:52,260 --> 00:35:58,260
music and primarily listen to it how

890
00:35:55,920 --> 00:36:01,260
long did it take you to kind of start

891
00:35:58,260 --> 00:36:04,560
playing it as an instrument and and what

892
00:36:01,260 --> 00:36:06,240
was the process so I I'll have to admit

893
00:36:04,560 --> 00:36:08,579
like I said at the start I am an

894
00:36:06,240 --> 00:36:11,220
engineer who got into this from a very

895
00:36:08,579 --> 00:36:14,460
minimal musical background so playing it

896
00:36:11,220 --> 00:36:17,339
musically I if I'm completely honest is

897
00:36:14,460 --> 00:36:19,740
probably a little bit of a stretch like

898
00:36:17,339 --> 00:36:23,400
um so far the best things that I've done

899
00:36:19,740 --> 00:36:25,200
if I'm honest essentially like covers of

900
00:36:23,400 --> 00:36:28,560
pieces that I've seen other people

901
00:36:25,200 --> 00:36:31,619
mainly on YouTube create so

902
00:36:28,560 --> 00:36:33,660
um like I watched like there was a video

903
00:36:31,619 --> 00:36:36,240
similar to Bob's video there's actually

904
00:36:33,660 --> 00:36:39,240
like I should have mentioned a whole

905
00:36:36,240 --> 00:36:41,640
community of people on YouTube who make

906
00:36:39,240 --> 00:36:45,359
videos and they have to be in a

907
00:36:41,640 --> 00:36:47,640
particular uh format and style like

908
00:36:45,359 --> 00:36:49,680
there's certain conventions like

909
00:36:47,640 --> 00:36:51,839
normally you have little trinkets that

910
00:36:49,680 --> 00:36:53,940
are on the table next to the device or

911
00:36:51,839 --> 00:36:55,140
there's specific lighting that's being

912
00:36:53,940 --> 00:36:56,640
applied

913
00:36:55,140 --> 00:36:58,859
um so there's that whole like kind of

914
00:36:56,640 --> 00:37:01,200
sub community of people out there making

915
00:36:58,859 --> 00:37:03,540
that music and so

916
00:37:01,200 --> 00:37:06,540
what I've done as a starting point as a

917
00:37:03,540 --> 00:37:09,300
complete musical Noob is to essentially

918
00:37:06,540 --> 00:37:11,760
do I guess what visual artists do in

919
00:37:09,300 --> 00:37:15,240
terms of starting out by often copying

920
00:37:11,760 --> 00:37:17,820
like great Masters or famous like

921
00:37:15,240 --> 00:37:20,520
paintings I started out by essentially

922
00:37:17,820 --> 00:37:23,700
trying to do like covers of not not

923
00:37:20,520 --> 00:37:25,619
famous pop songs or anything but just of

924
00:37:23,700 --> 00:37:28,020
pieces that other people have done on

925
00:37:25,619 --> 00:37:29,940
similar devices usually I've tried to

926
00:37:28,020 --> 00:37:31,980
find a similar but not the same device

927
00:37:29,940 --> 00:37:33,480
so then I'm not directly just copying

928
00:37:31,980 --> 00:37:36,240
I'm kind of like trying to figure out

929
00:37:33,480 --> 00:37:37,020
what the what technique and what

930
00:37:36,240 --> 00:37:39,839
um

931
00:37:37,020 --> 00:37:41,460
settings or like techniques they've used

932
00:37:39,839 --> 00:37:43,680
on their device and then try and do

933
00:37:41,460 --> 00:37:44,760
something similar on the device I'm

934
00:37:43,680 --> 00:37:48,839
using

935
00:37:44,760 --> 00:37:49,859
so yeah it's it's in some ways

936
00:37:48,839 --> 00:37:52,760
um

937
00:37:49,859 --> 00:37:55,079
like I I'd say it's in some ways a very

938
00:37:52,760 --> 00:37:56,900
appealing approach for someone coming

939
00:37:55,079 --> 00:37:59,460
from an engineering software background

940
00:37:56,900 --> 00:38:01,800
versus a musical background like people

941
00:37:59,460 --> 00:38:03,480
who come from a musical background and

942
00:38:01,800 --> 00:38:06,060
I've who I've talked to about this sort

943
00:38:03,480 --> 00:38:08,940
of thing have often said oh that feels

944
00:38:06,060 --> 00:38:12,660
so mechanical or like I did a talk um at

945
00:38:08,940 --> 00:38:14,880
a Sydney Meetup about a month back uh

946
00:38:12,660 --> 00:38:17,160
similar to this and one guy in the when

947
00:38:14,880 --> 00:38:18,900
was it like time for questions there was

948
00:38:17,160 --> 00:38:21,839
one chap who was sitting in the audience

949
00:38:18,900 --> 00:38:24,320
who shout out me you've killed live

950
00:38:21,839 --> 00:38:24,320
music

951
00:38:24,420 --> 00:38:29,960
and he goes you were the death of proper

952
00:38:27,300 --> 00:38:32,160
live Pub bands and I went well

953
00:38:29,960 --> 00:38:33,839
possibly but

954
00:38:32,160 --> 00:38:36,300
um I think live Pub bands are still

955
00:38:33,839 --> 00:38:38,820
quite Alive and Kicking but I can see

956
00:38:36,300 --> 00:38:41,160
from a muse uh a more traditional

957
00:38:38,820 --> 00:38:43,680
musician's point of view how like this

958
00:38:41,160 --> 00:38:47,520
looks like a much more mechanical or

959
00:38:43,680 --> 00:38:48,780
less artistic approach but honestly when

960
00:38:47,520 --> 00:38:50,940
I've watched

961
00:38:48,780 --> 00:38:53,820
um people on YouTube who are much better

962
00:38:50,940 --> 00:38:55,740
than I am do it like there's so much

963
00:38:53,820 --> 00:38:57,300
like musical theater involved which I

964
00:38:55,740 --> 00:38:59,160
haven't even touched on like I literally

965
00:38:57,300 --> 00:39:01,200
bought musical theory for dummies to try

966
00:38:59,160 --> 00:39:02,700
and learn what things like chords and

967
00:39:01,200 --> 00:39:04,500
scales were because that's how little I

968
00:39:02,700 --> 00:39:06,480
knew when I started

969
00:39:04,500 --> 00:39:08,760
um how much musical theories involved in

970
00:39:06,480 --> 00:39:10,740
what they do and then also a lot of the

971
00:39:08,760 --> 00:39:13,320
manual dexterity like

972
00:39:10,740 --> 00:39:16,920
um I'll try and post maybe like aft on

973
00:39:13,320 --> 00:39:19,079
my Twitter and Macedon just some links

974
00:39:16,920 --> 00:39:21,000
to people's performances just to show

975
00:39:19,079 --> 00:39:24,420
like just kind of at the professional

976
00:39:21,000 --> 00:39:26,280
level how like involved it is and so

977
00:39:24,420 --> 00:39:27,300
really like I don't think the criticism

978
00:39:26,280 --> 00:39:31,800
that it's

979
00:39:27,300 --> 00:39:33,359
not uh and as well the type of music as

980
00:39:31,800 --> 00:39:38,099
more traditional or classical music

981
00:39:33,359 --> 00:39:39,599
genres are is valid so yeah hopefully

982
00:39:38,099 --> 00:39:42,060
that answers your question like my

983
00:39:39,599 --> 00:39:45,000
skills are very much

984
00:39:42,060 --> 00:39:46,920
um early stage so that's why I did not

985
00:39:45,000 --> 00:39:49,280
play any of the compositions I've done

986
00:39:46,920 --> 00:39:49,280
so far

987
00:39:49,680 --> 00:39:54,839
well thank you so much Max and I think

988
00:39:52,560 --> 00:39:58,579
we can all join in in a round of

989
00:39:54,839 --> 00:39:58,579
applause for Max thank you very much
