thanks to things taught via this list am now with isthisokay.ck like this: SinOsc s1 => Gain g1 => dac; SinOsc s2 => g1; SinOsc s3 => PRCRev g3 => dac.left; SinOsc s4 => PRCRev g4 => dac.right; .25 => g1.gain; .25 => g3.gain; .25 => g4.gain; fun void ri() { while(true) { 300::ms => now; s2.freq() * Std.rand2(16, 32) / 16.0 => s3.freq; } } fun void ga() { while(true) { 330::ms => now; s2.freq() * Std.rand2(16, 32) / 16.0 => s4.freq; } } //let's try sporking it spork ~ ri(); spork ~ ga(); while( true ) { Std.rand2(32, 64) * 27.5 / 32.0 => s1.freq; 1000::ms => now; s1.freq() * Std.rand2(8, 16) / 4.0 => s2.freq; 250::ms => now; } am happy with the result it gives but began to wonder why s2.freq() in the fun doesn't result into an error when activated funs are sporked before the main loops starts ... so s2.freq() might have nothing when funs want to claculate things maybe SinOsc s3 => PRCRev g3 => dac.left; SinOsc s4 => PRCRev g4 => dac.right; gives some sort of default for .freq? then at the beginning am having s3,s4 making non-overtone but random note that has nothing to do with 27.5hz? tia -- 2g http://micro.ispretty.com
