[chuck-users] exponential envelope

Hmm. The documentation agrees with you: "Lookup can either be done
using the lookup() function, or by driving the table with an input
UGen, typically a Phasor."

I tried to drive the Gen5 ugen with an envelope, but that didn't seem
to work (or do anything at all). I tried a few other variations on
this idea with no result. Maybe this is not what you meant, and what I
am doing is completely silly.

Noise n => Envelope e => Gen5 curve => dac;

[0., 1., 0.] => curve.coefs;
500::ms => e.duration;

while (true) {
        e.keyOn();
        1::second => now;
        e.keyOff();
        2::second => now;
}

Let me know what you think. I appreciate the help.
Thanks,
