Hi and thanks. There's no central manual for MIDI Designer. Had you imagined this functionality you could've googled:
renumber controls midi designer
but you'd have to know it exists.
Manual is coming, but right now our focus is on growing and perfecting the App. We answer stuff here on Q&A and via Email very fast... it's not a manual but it should serve as some consolation.
Thanks!
