[chuck-users] Can I use ADSR UGen to envelope parameters other than gain (e.g. pitch)?

[Michael Heuer]

Yes, I use the following pattern often

220.0 => float f;
SinOsc osc => dac;
ASDR adsr => blackhole;

spork ~ updateAtSampleRate();

fun void updateAtSampleRate() {
  while (true) {
    f + adsr.last() * f => osc.freq;
    1::samp => now;
  }
}

There is also this pattern, which tries to encapsulate the above (whatever
you chuck into cv Gain(s) are provided as float parameter(s) to the tick
method)
