Re: [chuck-users] driving filter frequency from an envelope?

Andrew: Thanks for the code. I mostly wanted to know if there was a way to control filter frequencies working entirely at the UG level, without resorting to the: 1::samp => now; construct. Thanks. - Rob On 23 Apr 2009, at 09:07, Andrew C. Smith wrote:

Robert, This should work for you--sporked shreds run concurrently. A few things: I changed your Phasor to Step. This way you can set the multiplication value from any other shred, anywhere in the code without changing the "envdrive" shred. I don't know a ton about the computational thing, but basically with this method you're just controlling what the control rate is for every individual item. Everything is treated as audio, so it's up to you to decide what kind of signal fidelity you need if it's control or audio.

Blit b => ResonZ z=> dac; Step constant => Envelope e2 => blackhole; constant.next(1.0);

while(true) { spork ~envdrive(); 10::second => now; }

fun void envdrive(){ now + 10::second => time then; e2.time(10); e2.value(0.01); e2.target(2.0); e2.keyOn(1); while (now <= then) { 1::samp => now; e2.last()*440.0 + 100 => z.freq; } }

So: is there a way to directly control the resonant frequency at the UG level without breaking back into "user code"?

No, sorry.

(that was a easy one! :¬) )
