Re: [sc-users] Multi-voice sound file to single-voice sound files



If you hit the bug... this will work:

s.boot;

(	
// make this the path to your soundfile... this is a test file I used with three channels
	f = SoundFile.new("sounds/DyneTromBF.aif");
	f.openRead;
	f.numChannels;
	f.close;
	f.path;
	
	c = Condition.new;
	
	Routine.run({
		f.numChannels.do({arg i;
			s.sendMsgSync(c, \b_allocReadChannel, 0, f.path, 0, 0, i);
s.sendMsgSync(c, \b_write, 0, "sounds/"++f.path.basename++i+ +".aiff");
			("Channel "++i++" saved").postln;
		})
	})
)

hi,

there is a bug in the "/b_readChannel" implementation of scsynth :

b = Buffer.alloc( s, 32768 );
s.listSendMsg( b.readChannelMsg( "/Volumes/Loomis/Kalligraphie/ Papier1.aif", 0, 32768, channels: [ 0 ]))
----> "Channel mismatch. Requested 2 channels. Buffer has 1 channels."
s.listSendMsg([ "/b_readChannel", b.bufnum, "/Volumes/Loomis/ Kalligraphie/Papier1.aif", 0, 32768, 0, 0, 0 ])
----> ok works

the error occurs when a completionMsg is provided. seems it counts the last argument for another channel index...

ciao, -sciss-
