There are two types of MIDI note off message - '9c nn 00' and '8c nn vv',
where c is channel, nn is note number and vv is velocity.
You can see that only the 8c type supports release velocity, but the
advantage of the 'zero velocity note-on as note-off' is that you don't
interrupt running status for note-offs.
I assume whatever you're feeding your P3 with uses 8n type note offs.
The problems have all been related to 9c type note offs with running status.
My controller keyboard uses 8c because it sends release velocity, but this
isn't too common.
Fortunately, since my controller is now built into my E&MM Spectrum, and is
passing through a PIC that handles both internal CV conversion and master
keyboard output, I've been able to change it to different styles of output
for testing P3.
Which is nice.
