I've been searching for a similar request but didn't find any... - .reabank files currently support Bank/Program Change - MIDI editor can load .txt files with note names How about a unified file format for MIDI devices with the above: - Bank/Program Change - Control Change - Notes - .ini-like options to set per-file default MIDI editor view configs (PianoRoll/NoteNames and Rectangles/Triangles/Diamonds) The MIDI editor would only care about the 3 last entries and ReaMIDIControl about the 3 first. Other ideas: - Device name - MIDI in port - MIDI out port Those could be used to create a default ReaMIDIControl/MIDI Editor/Hardware MIDI port preset for each file found in the Reaper directory at startup
