Well, the basic idea is to take some signal in a buffer and play back bits
(grains) of it, especially small bits, typically around 50::ms (give or take
a few octaves). The 50::ms comes from that being the threshold where human
hearing will still detect pitch (20Hz) You can play back just a few grains
every once in a while, resulting in a rhythmical pattern or lots&lots of
them for noisy textures. A simple intro is found here as well;
There are some examples in the LiSa examples ( /examples/special/ ), but
those might not be general enough for you.
I'll cook up a example for you tonight or tomorrow or so, could be fun. :¬)
