Supercollider
Introduction
Supercollider (SC) operates in the same vein as the bytebeat project but at a higher level. The computer music workstation has SC installed.
Supercollider Class
Starting the first week in Feburary 2018, there will be a weekly class on Supercollider, lasting for 12 weeks. Details on the Supercollider Class page.
Example code
The following is an algorithmic composition in the SC language by Fredrik Olofsson, published on Twitter. It must be executed in the SC virtual machine.
play{a=LFCub;Splay.ar(a.ar(b=2/(2..9))%a.ar(b/5)*a.ar(2**a.ar(b/8)>0+1*2*(b*[300,303]-(a.ar(b/9)>0*50).lag2))*a.ar(b/6,b))}
This is not a limitation of the language though. It can be written in a much more expressive way, and lends itself to livecoding as a performative activity.
For example, the following creates a synth definition, followed by four instances of that synth with different parameters. Each code block can be executed as a piece, and the engine runs the code blocks in realtime.
// Define a single synth that takes parameters SynthDef.new("impulse-sinefunc", { | impulseLFO = 0.49, panPos = 0.5, lfoRange = 833, sinFreq = 435 | Out.ar(0, Pan2.ar( Decay2.ar( Impulse.ar( LFCub.kr(1,0.33,1,impulseLFO), 0 ),0.09,0.4,SinOsc.ar(sinFreq,0,0.25,0) ),panPos) )} ).add; // mess around with these four starting at different times x = Synth.new("impulse-sinefunc",[\impulseLFO,5.5,\panPos, 0.2, \sinFreq, 457]); x.free; y = Synth.new("impulse-sinefunc", [\impulseLFO,5, \panPos, 0.7]); y.free; z = Synth.new("impulse-sinefunc", [\impulseLFO,4, \panPos, 0.3,\sinFreq, 488]); z.free; a = Synth.new("impulse-sinefunc", [\impulseLFO,4.2, \panPos, 0.8,\sinFreq, 444]); a.free;
