Hi Ron. Found this older thread, but it fits my question:
The MIDI Forward works perfectly with Nixie, when both the MIDI in and MIDI out are used with separate cables. However, it does not work when bidirectional MIDI is activated and a splitter cable is used. Would it be possible to have bidirectional communication to the USB port using just the MIDI out?
The MIDI cable setup works with my previous controller, who also has a MIDI interface mode
There isn't support for that currently, but it's possible to be added later.
