method:: playN

playN is a multichannel play method for link::Classes/Monitor:: and link::Classes/NodeProxy:: (see also: link::Classes/ProxySpace::, link::Classes/Ndef::) that supports playing proxy outputs over strong::non-adjacent channels::; somewhat like a splitter/line mixer.

code::
// examples

s.boot;

p = ProxySpace.push;
s.scope(8);

	// a 3 channel test sound
~test3 = { SinOsc.ar([2, 3, 5] * 100) * 0.2 };

	// compare: play out of 3 adjacent channels
~test3.play(3);
~test3.play(6);

~test3.stop;
~test3.play;	// play remembers old (series) output settings;


	// outs
~test3.playN([2, 4,7]) // playN to 3 non-adjacent channels

	// set outs, amps and vol:
(
~test3.playN(
	outs: [2,3,5],
	amps: [0.5, 0.25, 0.125],
	vol: 1
);
)
~test3.vol_(2);

~test3.stop;
~test3.playN;	// remembers last state.

		// if playN has been used, one can set outs while playing.
		// note: this does not work reliably with the .play method!
~test3.monitor.outs_([3,2,1]);

		// set amps while playing.
		// note: this does not work with play method!
~test3.monitor.amps_(1/[1, 2, 3]).vol_(1);
~test3.playN;
~test3.monitor.outs_([2, 4, 7]);


	// one can also spread out one channel to several, with given amplitudes:
(
~test3.playN(
	outs: [1, 3, [5,6,7]],
	amps: [0.5, 0.25, [0.125,0.25, 0.5]],
	vol: 2
);
)

~test3.stop;
~test3.playN;

		// do changes while off:
~test3.stop;
~test3.monitor.outs_([2, 4, [5,6,3]]);
~test3.monitor.amps_(1/[1, 2, [3,2,1]]);
~test3.playN;

		// the most comfortable way to edit those parameters is using a text file:
~test3.playNDialog;


	// output mapping can be prepared before playN is used:
~test3.clear;

~test3 = { SinOsc.ar([2, 3, 5] * 100) * 0.2 };

~test3.vol_(0.5);		// vol can be set already

	// outs and amps require making a monitor first;
~test3.initMonitor;

~test3.monitor.outs_([3, 5, 6]);

~test3.monitor.amps_([1, 2, 3]);

~test3.playN;

~test3.end;
~test3.clear;
