MIDI Volume or Velocity Change results in part muted MIDI sound

[gavriil1]

Hi guys. This happens intermittently (not sure what is different when it happens). When I make a MIDI, or a MIDI velocity change volume (to a part of my score), many times, my instrument sounds like it's part muted. I use an Oxygen 88 controller. Any ideas?

I have filtered it down to an Xpand2 problem. Because restarting PT10 or restarting the controller, did not help. Because the way to go around this I had to:

1. Create a new track
2. Alt-Copy Xpand to the new track
3. Copy my MIDI notes to the new track
At this point the problem is still there.
Only when I click to a different Xpand instrument (say I go one instrument up with the plus button) and THEN come back down to my initial instrument (click on the minus button for one down), I get the instrument to respond with all "its might". What am I missing here?

Bump. No one guys has any clue?
