Looping on the Critter and Guitari Organelle

Hi Sylvain, the organelle looks fantastic! Do you have any videos using it as a looper?

I finally got around to making a video!

While it's fun to loop on the Organelle, I bought for another purpose (generative drums) and I find its audio inputs too noisy for my tastes. With a noise gate and a strong signal, it kinda works (you be the judge).

This patch adapts Marco Baumgartner's ALFALOOP looper for the Organelle (info: http://marcobaumgartner.com/#puredata/ALFALOOP).

The record function is mapped to the lowest C key on the Organelle. Pressing record once starts recording and pressing it again will close the loop and begin playback. As you'll see in the video, you can resize the loop with subsequent recording.

There are many overdub keys that are each quantized to various divisions of the loop length: 1/7, 1/8, 1/9, 1/11, 1/12, 1/24 and 1/48 (from F key chromatically up to C). Overdub will start on the next division of the loop corresponding to the key pressed and will last as long as that key is held down, but will end on the next subdivision after the key is released. This scheme allows some crazy rhythmic fun (see video).

There are four parameters controlled by the organelle's four knobs (from left to right):
- Feedback: Controls how much of the loop (volume) will remain on the next loop repetition.
- Ducking (secondary feedback): Controls how much of the loop (volume) will be mixed with the overdubbed audio from the inputs.
- Multiple: Multiplies the divider of the overdub keys (e.g. moving from 1 to 2, 1/7 becomes 1/14).
- Dry/wet mix

Thanks to:
- RJDJ for the crossfader
- I got a noise gate from this page: https://ccrma.stanford.edu/wiki/Stompbox_2012
- Marco Baumgartner for ALFALOOP
- Whoever I forgot (sorry)
