[chuck-users] Intraspection - an example of what I'm attempting

[Rich Caloggero]

Whan I run the following code, I get an error at line 7 - class UGen has no 
member 'mix'.
How do I do this type of thing in chuck?


// code
SinOsc s => Chorus chorus => JCRev reverb => dac;
880.0 => s.freq;
.2 => s.gain;
UGen @ ug[];
chorus @=> ug[0];
reverb @=> ug[1];
0.0 => ug[0].mix;

while (true) {
1::second => now;
} // main loop
