I was wondering if it would be possible to create a version of the microscale modifier that uses Midi Tuning Standard (MTS) messages. Specifically, it would send a single note real-time tuning message ahead of each note instead of a pitch bend message.
The big advantages of MTS is that it’s more accurate than pitch bends, and it doesn’t require channelizing the midi notes into one note per channel to work, so it will work on devices without multitimbral or MPE support.
The disadvantage is that the receiving device has to be able to respond to the message. However, the Novation Peak / Summit, Korg minilogue / micrologue / prologue, and DSI’s recent synths all do. The Tooro is also slated to have this.
I can help with details of the implementation if needed, but the needed info is here: http://www.microtonal-synthesis.com/MIDItuning.html (realtime messages).
