Re: [sc-users] how to tell when n_set messages have been executed

[Sciss <contact@xxxxxxxx>]

totally strange. even if you initially wait _two_ control blocks, the  
reported value might still not have been updated:

~synth = {arg freq=440; SinOsc.ar(freq:freq)}.play;

(
Routine({
  ~wait = true;
  100.do{
	~new_freq = rrand(400, 600);
	~synth.set("freq", ~new_freq);
	("waiting for freq "++~new_freq).postln;
	while({~wait}, {
	  (s.options.blockSize*2/s.sampleRate).wait;
	  ~synth.get(\freq, { arg value; ("freq is "++value).postln;
		// has the synth been updated?
		if (value == ~new_freq, {~wait = false;"Synth control  
updated!".postln}, {"waiting... ".postln});
	  });
//	  0.0001.wait;
	});
	~wait = true;
  };
}).play( SystemClock );
)

i.e. i still get "waiting..." here a lot. something with the server  
scheduling must be definitely be broken, i assume?

ciao, -sciss-
