Would be great to have a way to explode a pattern/Bank - each pad and corresponding midi data would get split into a new Bank with that pad and a new pattern with just that pads midi data.
I think there's a request of having the banks behave as 'track folders' on the song time-line.
This would also make it easier to copy parts between patterns.
Due to the 'pattern nature' of BM3 if/when a bank is 'exploded' there would be a need to automatically create new patterns if a pad/track-pattern from a bank is copied/moved to a place on the time-line that doesn't already have a 'target pattern'.
"Sub-tracks" are in the backlog for sure!
Unfortunately audio clips are kind of windows 3.11 on the timeline right now, so that is no workaround in a lot of cases.
