That may be clearest problem statement I have ever read on this site.

My first reaction was, is the Yamaha sending MIDI Note Off, but you answered that. My second reaction was to filter the MIDI input (as some do with wind controllers that spew a huge number of messages) but you answered that.

Have you tried writing directly to Support@pgmusic.com ? We are only fellow users here. Further, the number of us who use MIDI actively appears to be a small subset that shrinks more each year.
