i think it would be cool for an option to use the midi tracks rather as more flexible type machines allowing different functions within the pattern (assuming you aren’t sending midi to anything). “midi track” being just one option out of a few.
like perhaps be able to use them as different pattern fill (scenes of some sort i guess)… or different pattern sequence order
like by default the sequence is always playing forward (step 1,2,3,4,5,6,7,8… etc. or whatever pattern lengths is set in the page functions), but then you could press say pad 9 and the pattern/tracks lengths will change to a different configuration. or maybe the play order is 1,3,5,7,9. pad 10 would do something different… and so on.
or maybe they allow switching between different conditional plocks… allowing the ability to change how the probability is happening on one pattern.
so basically instead of midi, there is option to use buttons 9-16 are ‘scenes’ which control different and customizable track lengths / play order / probability… like scatter on the roland stuff but user designable, classy and without all the cheese - so it is less about fx and more about providing even more variation within the one pattern.
…oh and one more… for whatever drum track is selected, buttons 9-16 could be used to set different settings for that samples start, length and loop settings…
