| − | Implementation of real time, time granulation synthesis in Chuck, with the ability to be used in live performance. The synthesis parameters (grain length, position, position randomness, pitch, and pitch randomness) can be tweaked in real time.

| − | SndBuf stores a sound file into a buffer, which is then chucked to a linear envelope for the grains. The envelope used in the sound files below has a rise time that is randomly chosen from 0.45 to 0.5 ms. This can be altered to change achieve a more varying asynchronous envelope for each grain. For granular synthesis, grain length is usually from 1 - 100 ms. The grain length, position in the sound file, the randomness of the position, pitch transposition, and randomness of pitch are the parameters that can be controlled in this patch. All the parameters were mapped to a midi controller, allowing for real time control of each parameter simultaneously.
