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

[Mario Buoninfante]

Hi,

yap, the following is a possible solution:

Step step => ADSR adsr => SinOsc oscil => dac;

step.next(500);
adsr.set(5::ms, 150::ms, 1, 500::ms);

while(true){
    adsr.keyOn();

    400::ms => now;

    adsr.keyOff();

    1000::ms => now;
}

cheers,
Mario
