Re: [Sc-devel] PsyCollider 3.1 - Server side scheduling fixed

["James Harkins" <jamshark70@xxxxxxxxx>]

Hi Chris,

Oh... I'm really sorry to have to do this to you. It works somewhat
better, but the timestamps are still off.

An example like this should produce blips exactly evenly spaced --
since the timestamp should be the logical time (which, on successive
events, should always be 0.125 seconds since the last one) + latency.
With a 64-sample block size, timing errors from the Out UGen rounding
to the next block boundary are undetectable.

SynthDef("sine", { Out.ar(0, (SinOsc.ar(440, 0, 0.2) *
EnvGen.kr(Env.perc(0.01, 0.05), doneAction: 2)) ! 2) }).send(s);

a = Synth.basicNew("sine", s, -1).newMsg;
r = fork {
	loop {
		s.sendBundle(0.2, a);
		0.125.wait;
	}
};

r.stop;

I thought, maybe the block size is higher than on the Mac because of
some windows driver requirement. So I tried OffsetOut instead of Out
in the SynthDef and scsynth.exe promptly crashed. :(

Or, are you perhaps measuring the latency from the time scsynth
received the message? That isn't reliable.

It's better, but I'm afraid there's still some work to do...
