A very simple buffer player for sound file playback in SuperCollider. This one is for a live diffusion of a stereo file to an 8 channel setup, where the left track of the sound file goes to the first 4 output busses and the right track goes to the last 4 output busses. Amplitude of each channel is controllable by setting parameters \amp1, \amp2,…

// Prep
Server.default.boot;
Server.default.scope(8);
 
(
~play = { | path, out = 0 |
  if (~buffer.notNil) { ~buffer.free };
	Buffer.read(
		Server.default, path, action: { | buffer, out = 0 |
			~buffer = buffer;
			~synth = { | out = 0, amp1 = 1, amp2 = 1, amp3 = 1, amp4 = 1, amp5 = 1, amp6 = 1, amp7 = 1, amp8 = 1 |
 
				var left, right;
				"===================== STARTED ===================== ".postln;
				#left, right = PlayBuf.ar(2, buffer, BufRateScale.kr(buffer), doneAction: 2);
				//				Out.ar(out, [left, left, left, left, right, right, right, right])
				Out.ar(0, [left, left, left, left, right, right, right, right]
					* [amp1, amp2, amp3, amp4, amp5, amp6, amp7, amp8]
				)
			}.play(args: [\out, out]);
	})
}
)

// example of usage
~synth = ~play.("/path/to/my/audiofile.wav");


~synth.set(\amp1, 0.1); // lower the amplitude of channel 1 output

~synth.set(\out, 8); // Set the output busses to busses 8-16 (= internal busses)
