Here's another feature suggestion/request. Don't know if this is perhaps possible in some way already, if so, please tell me how.

I'd like to have something in the realm of granular looping, working like this:
Say you have a loop of length l. Already, it's possible (using multiply) to cut out a sequence starting at x<l and of length e, so the portion of the original loop which gets played back is from x to x+e.

What I'd like to have is the possibility to control x (after this segment has been defined) by a MIDI controller, thus being able to scroll your short segment through the whole original loop.

More tech details:
This would require to move the current playback position with the moving x as well. Say your playback position is p and during the time interval for controller sampling t this position changes by d, then if you change e by de, the playback position needs to change by d+de (thus playing back faster or slower through the loop, depending in which direction you move e).

Additional options:
It would also be possible to make e adjustable by a controller. I would however suggest that after the original e is defined (e.g. by multiply, or by a new process), e can only be decreased by the controller. Why?
Simply, if your original loop length l is, say, 30 seconds, then with MIDI controller quantisation, the step size in which you can set e would be 30/127=236ms, which seems to coarse to me for fine-tuning e (especially if you consider that you usually have a hard time to reach one specific CC value with a foot controller).

This is a cool function I too would appreciate! For a pre recorded sample we had it long ago in the early Emax samplers and today it can be done with the software sampler Kontakt. Those early techno "robot voices" were produced by sweeping a narrow loop through a longer sample, probably with the Emax.

Being able to do this with real-time recorded audio in a looper would write history!

Just -refound that (free) VST which does something like that - but unlike what I'm suggesting here, it's not as "controllable" as having it in the looper (and obviously makes it kinda difficult to stay in the timing if running this post-looper):

have fun!
