crash dump from tonight?

Any idea what happened here? I was running code that I've run dozens of  
times before without incident, with and without Exception.debug = true  
(it was set to true here).

I relaunched sc, performed the same steps, and it ran without error, so  
I don't know why it was trying to get the backTrace to begin with. The  
code I was running has been tested pretty thoroughly and it works well.

Probably can't be diagnosed from this, but I thought I'd ask anyway.

buffer alloc error

after sending a OSC message to scsynth:

"b_allocRead",1,"samples/clap.wav",0,0

I get next error:

subgraph starting at SuperCollider timed out (subgraph_wait_fd=15, status = 0, state =
Running)
client SuperCollider error: awake_at = 120396905 state = 2 timed_out = 2
RESULT = 9

whole node tree gets emptied and scsynth gets unresponsive.

sending message with a 0 buffer ID is OK. Any other , I get the same error.

What OS are you running on? I've never seen that error on Mac OS X.

Well it figures, it's not Mac OS.
I'm running Gentoo linux (kernel 2.6.9 / gcc 3.3.4 /  glibc 2.3.4 ).

Feedback / Requests

Hello all, I found SC a couple of months ago and have been lurking here for a 
while. I'm very happy I did find it, it's a freaking amazing program, dude! 
Kudos to everybody involved.

So now I've got some stuff, questions and the like:

*Could you make scsynth not write any diagnostics to stdout when doing 
non-realtime synthesis to stdout. Reason is, I like to oversample heavily to 
reduce aliasing -- outrageous use of FM introduces aliasing -- and feed 
scsynth's output to sox for upsampling. Nicer to use a pipe than fill the disk 
with intermediate files.

*Slight correction to help files: Limiter (and Normalizer, I guess) actually 
delays by 2*lookahead, not by 1*lookahead.

*Could somebody write a Limiter that accepts a control signal, like Compander 
does? I haven't been able to whip up a stereo limiter using the available 
ugens.

*Anybody working on ugens such as the Moog VCF or some waveguide stuff? I 
notice physical modeling stuff is just about the only synthesis technique not 
covered by the existing ugens. There's not even a Karplus-Strong model, or is 
there? Several Moog VCFs can be gotten from musicdsp.org archives -- a good 
source for other stock DSP algos -- and I can provide the code for this, if 
someone is willing to integrate it.

*I coded a stereo-to-stereo feedback delay network ugen a while ago. It's 
called FDN. These things produce very nice diffusion for a reverb. Used 
Hausholder matrices for feedback. Say, 16 delay lines with a dual allpass on 
each line, the second allpass having its delay length modulated to add warmth

Re: Feedback / Requests

You can already feed a control signal into the level arg for Limiter.  
Is this what you are talking about?

Josh

s = Server.internal.boot;

s.scope(1)

{Limiter.ar(SinOsc.ar(440, 0, 100), SinOsc.kr(0.1, 0, 1), 0.1)}.play(s)

Re: Feedback / Requests

No, he's talking about limiting signal A based on the amplitude of
signal B (like you can do with Compander). That isn't possible with
Limiter as of yet.

I've changed CompositeFunction so that it creates a single object 
when multiple functions are chained up. This is one argument in 
favour of it, but I don't know if I should maybe better return it to 
the way it used to be.

fillRect small alignment error


(

f = { arg n;
	w = SCWindow("plot", Rect(128, 64, 360, 360));

	w.drawHook = {
		var h, v;
		v = h = 300.0;
		Pen.use {
			Color.black.set;
			10.do {|i|
				n.do { |j|
					Pen.fillRect(Rect(h / 10 * i, 
v / n * j, h / 10, v / n));
				}
			}

		}
	};

	w.front;
}
)

f.(11); // little gaps
f.(12); // now they are gone

maybe this is in core graphics though.

[commit] pass inval through operator streams

the inval is now passed through operator streams, which are the 
result of unary and binary operations on patterns. So this works now:

a = Prout { arg in;
	loop {
		in = 100.yield;
		3.do { in = if(in > 4) { 2.yield } { 0.yield } }
	}
};

b = Pseq([1, 2], inf);

c = (a + b).asStream;

c.nextN(8, 5);
c.nextN(8, 2);
