The SuperCollider code is stolen from redFrick’s blog post about cellular automata. All I have added is the SynthDef, one line at the top to set sound variables and one line in the drawing function to make new synths based on what blocks are coloured in.
Ergo, I haven’t really got anything to add, but this is still kind of fun and Star-Trek-ish
(
SynthDef(sinegrain2, {arg pan = 0, freq, amp, grainDur; var grain, env;
env = EnvGen.kr(Env.sine(grainDur * 2, amp), doneAction:2); // have some overlap
grain= SinOsc.ar(freq, 0, env);
Out.ar(0,Pan2.ar(grain, pan))}).add;
)
//game of life /redFrik

// add sound-related variables
