In Hauptwerk, I need to display the crescendo stage. I just used a knob. It is not meant to be a control, since you are crescendo'ing with the pedal, but it can be. Native crescendo goes 1-40, Hauptwerk crescendo goes to 31.
In future Hauptwerk update, I need to display the master combination stepper frame (both current and cued). Those are just status -- where you are, where you are going. I am not a good enough organ player to need 1000 combinations - I barely need 5 - but since it exists, I want to get it workin right in MD.
Finishing my RD-2000 Hammond preset keys (the reversed color keys, one octave) is still on my list. Still hard coded, but I want to have the preset bank selectable, so you would have a persistent display of which bank you selected. Would be nice to have each key display the currently assigned preset.
Ha, but my ideas far outstrip my available time. I could go on.
