Paul, here are my results from your most recent
release:

1) the MIDI no longer goes to both ports. Now it goes to A port only. Port B shows up in the dropdown menu, but if I select it, then exit and return, the port is reset to A

2) if I change the VW receive channel to 1, it now accepts patch changes, but it still doesn't change chords based on the notes that appear to be getting through (MIDI light still shows activity every time a chord is played)
