Re: [sc-users] How to SynthDef a non-stop player of random samples???

["Andrew C. Smith" <acsmith@xxxxxxxxxxxxxx>]

I think what you need is a Pattern that encompasses a SynthDef.  Check
out Prand or Pwhite for your random values.  This way, you can store
the pattern itself as a single variable and then instantiate a number
of these patterns.  If you want it totally random (within set high-low
parameters) Pwhite is probably the way to go.  This way, each synth
can randomly select its own buffer to play and as soon as the sound is
done with the CPU is freed.  You can probably figure out how to do
this in a couple of hours if you have the SynthDef built already.
Just use the Practical Guide to Patterns tutorial.

Yeah, the basic advantage to triggering individual synths is just that
you have that extra downtime where the synth isn't eating your CPU.
Also, if you free the pattern (in case you later decide that you DO
want to fade things out) it won't click the synth off but rather will
just not instantiate a new one.
