Introduction[edit]

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[edit]

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[edit]

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;
