Hey guys, first time posting here; short-time reader :)
I've run into a bit of trouble programming a function to fade a ugen in or out. The code below will work nicely on g.gain however I can't abstract it to affect anything else without controlling the reference object, in this case 'g.'
The input is time 'x' in number of seconds.
//==============================================// function void fadeOut(int x) { 1 => float master; x * 1000 => int top; for( 0 => int i ; i < top; i++ ) { if (master > 0) master - (master / (top * .2 )) => master => g.gain; 1::ms => now; } } //==============================================//
Obviously the below would be my desired function, but even delving through ChucK's string class, it doesn't seem that there's a function to return an object reference from a string...
//==============================================// function void fadeIn(int x, string y) { .01 => float master; x * 1000 => int top; for( 0 => int i ; i < top; i++ ) { if (master < 1) master + (master / (top * .2)) => master => y.gain; 1::ms => now; } } //==============================================//
Am I crazy for thinking something like this would be useful?
I'm not too sure what the meaning of the gain of a string would be, since it has nothing to do with audio... But perhaps you're looking for references. The following code seems to work.. SinOsc s => blackhole; 1 => s.gain; fun void cut(UGen@ x) { 0 => x.gain; } cut(s); On the other hand, I suggest using the Envelope ugen instead of manually fading the gain with a loop. Steve
