GrainStorm Ver1.0

GrainStorm is a granular synthesizer that repeats a short grain of audio from a designated recording to produce anything from rich pad sounds to imitations of real instruments. It comes with 10 pre-loaded samples which can be replaced with any .wav file under 8 seconds long.

Pressing the Aux button will toggle the reverb feedback rate to 100% resulting in an infinite sustain loop for massive pad soundscapes.

It supports 4 voices with a modifiable attack/release envelope and a lowpass filter that affects the overall signal.
