Implementing midi thru

I’m still interested but in something slightly diff. I want to have Organelle function like a midi looper. Anyone see anything like this?

Ideally, like a simple audio looper pedal: press a button and it’s armed to record. Start playing on a different midi controller and it starts recording (free form, no tempo base), press a button and it starts looping. Subsequent buttons go in and out of overdub mode. The midi out would go into other modules or play sounds in the organelle.

Super cool would be diff buttons record different loops or overdub parts.
