In SuperCollider you can do it IMO more easily. Then again, I'm biased (being an avid SuperCollider user for over 10 years). SynthDef(\sine, { |freq, amp = 0.1, gate = 1| var eg = EnvGen.kr(Env.asr(0.1, amp, 0.1), gate, doneAction: 2); Out.ar(0, SinOsc.ar(freq, 0, eg) ! 2); }).add; g = Group.new; p = Pbind(\instrument, \sine, \type, \on, \freq, 440 * Pseries(1, 1, inf), \amp, 0.1 / Pseries(1, 1, inf), \group, g).play; // when done: p.stop; g.release; If you want different amplitudes, substitute a different pattern after \amp. This example posits an inverse relationship between the partial's frequency and its amplitude, i.e., a sawtooth. Disclaimer: I wrote this on a tablet without testing the code... and we all know how that usually turns out. There could be mistakes, but the principle is right. Again IMO (and admitting my bias), if you have to make a choice between learning csound or SuperCollider, choose SuperCollider. hjh _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-user
