This might be shameless plug for a few Chugins I created, but I thought it
might be up your alley.
I made two Chugins a while back that deal with atypical envelope types, one
for power based envelopes, and one based on window functions. I enjoy using
window function envelopes for sine sweeps other types of control; here are
two short examples.
This is the power based Chugin.
PowerADSR pow => blackhole;
// envelope durations
pow.set(10::ms, 10::ms, 1.0, 10::ms);
// curves for attack, decay, and release
pow.setCurves(0.5, 2.0, 0.5);
spork ~ printValue();
pow.keyOn();
20::ms => now;
pow.keyOff();
10::ms => now;
fun void printValue() {
while (true) {
<<< "Power ADSR Value:", pow.value() >>>;
1::ms => now;
}
}
And here is the window function based Chugin.
WinFuncEnv win => dac;
// set for a Blackman window
win.setBlackman();
// envelope durations
win.attackTime(25::ms);
win.releaseTime(25::ms);
spork ~ printValue();
win.keyOn();
25::ms => now;
win.keyOff();
25::ms => now;
fun void printValue() {
while (true) {
<<< "Window Value:", win.windowValue() >>>;
1::ms => now;
}
}
