In this video demo we use 4 granular processors, 4 envelope generators (ADSRs) and 2 LFOs (modulating granular selection window start/length).

We play the granular processors using a MIDI keyboard. The MIDI notes are automatically assigned to these "four voices". Each granular processor is modulated by its own ADSR envelope.

In the video I play with grain duration, grain frequency, selection window start and length. The granular processor uses a triangle window in this demo.

As you will notice you get interesting effects when each of the voices is using the same sample material but uses slightly different settings. The pitch, start position and length of the grains is randomized as well.

The sample used in the video is soundeffect_longtouch.mp3 by appdoc on Credit in the video."
