If you could provide me the image with diagrams of full MIDI note and CC assignments for each button/knob in all three layers. I'll then hopefully come up with something like you requested so you can test it out instead. I got mapping for IG with two combos, hotcues are straight forward and slicer is from MF too. If don't know how to find out MIDI notes follow this steps:

-Open preferences
-Controller manager
-Click "learn" (will highlight)

After that, any button you press or knob that you move will send unique MIDI assignment to controller manager and it should appear on screen. If you grab some time to finish this I would be glad to help with ideas.
