After many, many years of having this wonderful app I finally started poking around the multitimbral capabilities. This led to a realization that the keyboard, when split, functions as multiple MIDI keyboards on ascending channels (obvious in retrospect, but I just never considered it!). Finally, I recalled that Thumbjam can work as a slide-over app and, much to my delight, I had all 4 "keyboard" splits on the little overlay screen hovering above AUM.
A little bit of creative MIDI routing, augmenting ThumbJam's played output with Fugue Machine and StepPolyArp Unit, and some audio processing and I put this together: https://youtu.be/VV4V7ra5yKE
Jesse, thank you for making and maintaining this wonderful instrument!
