summary:: Demand rate generator for embedding different inputs

categories:: UGens>Demand

description::
Demand rate generator for embedding different inputs.
In difference to Dswitch1, Dswitch embeds all items of
an input demand ugen first before looking up the next index.

classmethods::
method:: new
argument:: list
array of values or other ugens
argument:: index
which of the inputs to return
discussion::
structurally related: link::Classes/Pswitch::

examples::
code::
(
	{
		var d, trig;
		d = Dswitch([
			Dwhite(3, 4, 2),
			Dwhite(0, 1, 2),
			Dseq([1, 1, 1, 0], 2)
		], Dseq([0, 1, 2, 1, 0], 2));

		trig = Impulse.kr(4);

		SinOsc.ar(
			Demand.kr(trig, 0, d).poll(trig)
			* 300 + 400
		)
		* 0.1 ! 2
	}.play;
);

// compare with Dswitch1:

(
	{
		var d, trig;
		d = Dswitch1([
			Dwhite(3, 4, 2),
			Dwhite(0, 1, 2),
			Dseq([1, 1, 1, 0], 2)
		], Dseq([0, 1, 2, 1, 0], 2));

		trig = Impulse.kr(4);

		SinOsc.ar(
			Demand.kr(trig, 0, d).poll(trig)
			* 300 + 400
		)
		* 0.1 ! 2
	}.play;
);
