For my control surface emulator I was using Note On/Note On controls, which work fine outgoing, but incoming messages are ignored. I've spoken with James K Hiser on Facebook and he mentioned I should raise the problem here - he has also confirmed it is not working for him either.
Can this please be raised as a bug for fixing?
I've coded a StreamByter workaround for this problem, but this has raised another problem, in that the StreamByter plug-in does not accept the 'BLOCK' command!
For anyone curious, here are a few seconds of my emulator in action:
