Little granular synthesis / time stretching tool I developed based on an NN-19.

Note that the file size is limited by the NN19′s limits (not very long)

Knob 1 is the speed at which the sample is player, switch 1 stops that speed (granular synthesis mode).
Knob 2 defines the sample size / frequency
Knob 3 is some fine tuning to get your granular synth in tune
Knob 4 is where you start on the sample / where you take your grain from.
Switch 4 softens the sound by adding a touch of very short reverb. Sounds good on some samples, not on other.
Switch 3 plays the sample in reverse, when in time stretch mode.

The idea behind this synth is to loop-read a very small bit of a sample through an NN19, and advance through the sample to fake some time stretching. If you don’t advance, you have a granular synth.

A compressor has been integrated in the unit for the simple reason that playing with the knobs real time can produce some peaks, this allows for more time to think for the musician.
