This shows a way to use internal CV to midi to automatically “hit buttons” in a loop. There are 2 loops setup (I midi map them to a foot pedal).
Loop two is the basic loop that isn’t effected by the internal CV changes. Loop 1 allows for internal CV toggling of the replace function when you press Foot Switch B. You can switch the call from replace to substitute if you want to be more subtle and I use a short loop (cell) to start and then multiply that out for a longer loop with small cycle. You can play around with quantizing the loop too (I’d recommend youtube videos by Andre LaFosse for great tutorials on looping).
