Okay so I'm having a bit of trouble figuring out how to take the current keyboard range and on each successive press of a button, shift it down by one octave. It has to be relative, because I also want an increment button as well.
I'm assuming it'd be something like:
event_button id=1 kb_transpose= current_value + 12
event_button id=2 kb_transpose= current_value - 12
Sorry if this has been covered before, (I looked but maybe I didn't search for the right terms?). Thanks for any help!
