Right. MIDIberry can only do one direction and Windows 10 apparently won't allow multiple instances of an app so I was trying to figure out how to augment it or replace it with another app to get the other direction. Those experiments have all failed so far due AX8-Edit not getting back the responses it expects. My guess is sysex isn't getting handled appropriately somewhere in the chain. I'm actually working on my own app just to do whatever is necessary to provide the adapter for AX8-Edit to BT LE MIDI on Windows. It's a fun learning experience if nothing else.
