I tried a few month ago those Triggering Slices with Mpc 1000, and it worked well. The principle is to send a Cc17, Cc48, and a note.
I sold my Mpc 1000 and now I prefer to use the pads of my keyboard, assigning CCs to them.
With my Ep+ midi processor i’d like to recall 2 scenes with one pad.
Connecting a midi cable between Ot’s Midi In/Out, it’s very efficient to control crossfader, with plock and/or lfo Design + random.
