piano in Dim Pro sounding like a violin

[lapasoa]

It happens from a long time that when I use a Dim Pro  piano and save the track, after doing some tweaking in other tracks, if I listen again to piano track the piano is soundinga like a violin or a cello. I have to close the project and reopen and the piano is sounding right. But after tweaking some track when I listen to Dim Pro piano is  one more time sounding like a viola or a cello..

Sounds like it's getting a CC72 message from somewhere that's raising the attack time. I've seen 3rd-party MIDI tracks do that. Check the Event list for any tracks routed to it.
