100 buffers with 3 minutes long tracks

#1

Hello,
What is the best way to feed 100 buffers with 3 minutes long tracks, and then to be able to control a single cue point that moves (and play) randomly from tracks to tracks at an extremely fast speed… A kind of a granular sampler that would be fed with thoses 100 tracks…I know Tgrains, but I don’t know what would be the best strategy with this amount of sources. (And by the way in term of buffer capacity is it possible?)
Thanks a lot.

This is a quite vague question, but …

… the amount of sources doesn’t make any difference. A control signal for the bufnum arg can move through all the buffers rapidly. However a grain from a different buffer would only be taken with a new trigger. You could also take a demand rate ugen as buffer input. Also in this case it doesn’t make a difference if you have 2 or 1000 buffers (s.options.numBuffers defaults to 1024, 100 buffers with 3 min length should be no problem, just checked with 300 of length 1 min).

b = [
	Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav"),
	Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01-44_1.aiff")
];

// bufnums

a = b.collect { |x| x.bufnum }


(
{
    var trate, dur, rate;
    trate = 3;
    dur = 1 / trate;
    rate = 1;
    TGrains.ar(
		2, 
		Impulse.ar(trate), 
		Dseq(a, inf), 
		rate, 
		1, // centerPos
		dur, 
		Dseq([-1, 1], inf), 
		0.1, 
		2
	);
}.scope;
)

Perfect, it works. thank you.
