Hacking Haskell in Nightclubs?
Real-time audio is much simpler these days due to SuperCollider, a truly excellent cross platform audio synthesis server by James McCartney. http://www.audiosynth.com http://supercollider.sf.net To communicate with the server one only needs to implement the most basic aspects of the Open Sound Control (OSC) byte protocol (in particular none of the pattern matching is required). http://www.opensoundcontrol.org/ To define 'instruments' there is a SuperCollider specific byte protocol for describing Unit Generator (UGen) graphs. I have an initial Haskell implementation of both these protocols at: http://www.slavepianos.org/rd/f/207949/ darcs get http://www.slavepianos.org/rd/sw/sw-69/ If SuperCollider is running on the local host at the usual port then: Hsc*> play' sc ab Hsc*> stop' sc should play (and then stop playing) the famous 'Analog Bubbles' test sound: ab = out AR 0 $ combn AR s 0.2 0.2 4 where s = sinosc AR (midicps f) 0 * 0.1 f = lfsaw KR 0.4 0 * 24 + o o = lfsaw KR (MCE [8, 7.23]) 0 * 3 + 80 The Hsc module can also write UGen graphs to the 'dot' language, so graphs can be drawn automatically, which can be useful for debugging. I have been working with scheme and SuperCollider for some time, but have been using haskell recently and generally like it very well. I don't think static typing is an issue. OSC messages can be timestamped, and SuperCollider has a sample accurate scheduling queue, so language timing jitter can easily be worked around. I think that the SuperCollider model is an excellent fit with languages like Haskell. Regards, Rohan On Mon Nov 28 21:35:38 EST 2005 Paul Hudak wrote:

Hello all, I read an article on using perl for live improvised synthesis a while ago (http://www.perl.com/pub/a/2004/08/31/livecode.html). Does anyone have thoughts in doing this is haskell? Would strong typing make "jazzy" programming too difficult?

Thanks, this is just what I've been waiting for! I believe the time-stamping of events, and a suitable scheduling queue, are critical for making real-time music. With the work you've done I suspect it would be pretty easy to build a SuperCollider backend for Haskore. -Paul

Yes, great! I also tested SuperCollider in the past but it was hard for me to get an overview of the documentation. The simplest way for me seemed to use the SuperCollider programming language and thus to write an Haskore backend translating into this language. But I prefer a direct (binary) connection to the SuperCollider server. Btw. I'm just collecting event list related code scattered in Haskore modules for MIDI, performance and my Haskell audio signal backend in order to setup a module for handling lists with time stamped events. This may be also helpful for SuperCollider then.

This is nifty, can you give an explicit license so I know how I can use it? "Setup.hs: Warning: No license-file field." -- Shae Matijs Erisson - http://www.ScannedInAvian.com/ - Sockmonster once said: You could switch out the unicycles for badgers, and the game would be the same.

My mistake, the Hsc.cabal file clearly states GPL. (I assume I can choose either GPL v1 or v2 ?) -- Shae Matijs Erisson - http://www.ScannedInAvian.com/ - Sockmonster once said: You could switch out the unicycles for badgers, and the game would be the same.
