Thanks a lot for the offer!
Well im actually looking for a general solution to do it many times with any (or many) samples.
I havent decided of that ONE loop but would rather have a set of 30ish loops to choose live and combine with the rytm.
These beats should then be on time (downbeats on equal distance) and adjustable in bpm (110-140bpm)
If it was only one or two loops i would actually do it in the DAW but i was hoping for an easy DAWless solution
