Re: [chuck-users] Why doesn't this work?

Cool, so I wasn't going crazy!

No, but it would be good to get into the habit of making sure divisions are never by zero. I do feel that it would be a good idea to have UGens make sure they don't get stuck at receiving a "nan" as I think quite a few do.

Yeah, I was inspired by the one-liners thread on the electro-music forums. I was aiming at a concise little four on the floor... Cool remix :)

Thanks. And good luck.

Thanks for the help.

Hey guys

Ey, Matt.

...

I'm trying to do a simple chuckle, but something's going wrong when I try to set s.freq...

SinOsc s=>dac;Phasor

p=>blackhole;p.freq(2);while(1){Math.sqrt(1/p.last())*100=>s.freq;10::ms=>now;};

...

...

Working towards a tweet? :-)

...

If I dump "Math.sqrt(1/p.last())*100" I get floating values as expected between 100 and 700, but when I chuck it to s.freq, no sound is output, and s.last() is always 0.

Am I missing something or is this a bug?

There is a bug here, I think. The as p.last() may be 0 (and will be when we start) the result will be infinity, or "nan" or some such thing. For reasons unknown this doesn't get through to the print yet still gets the UGen stuck. UGens do not like floats that aren't numbers, in my experience. Here is a version that works (with indentation, if you don't mind);

SinOsc s => dac; Phasor p=>blackhole; p.freq(2); while(1) { Math.sqrt(1/ ( p.last() + 0.0000001 )) * 100=>s.freq; 10::ms=>now; } As there was still some coffee left after finding the issue (interesting bug! and cool sound) I also made a remix.

SinOsc s => dac;Phasor p=>blackhole;

fun void add() { int foo; while (4::second => now)++foo%16 => p.freq; } spork ~ add(); while(1) { Math.sqrt(1/ ( p.last() + 0.0000001 )) * 100=>s.freq; 10::ms=>now; }
