We are going to demonstrate how to implement a new, completely different type of synthesis (or maybe better called a sound processing as the sound is not really synthesized). You can control parameters interactively (start, length of grain and number of voices), and replace the grain source material (or part of it) in real time. In result, this creates very interesting sounds and is a lot of fun to play.
The hardware is capable of sampling up to 1 second of stereophonic sound, and playing pieces of it back in parallel, as up to 40 grains per ear. The rest of the memory is reserved for echo/loop buffer, if that's not required, sampling time can be increased.
