Yamaha clavinova ( with proper definitions ) 
 
Example  I had a "harp" set on track 2.    I deleted all of the material on track 2, and copied a flute to track 2  ( changing the channel , and all instrument def's to a flute.
 
No matter what I do, it plays a harp.  I copied the clip to another track, and it plays a harp.. no matter what!   No matter where I put it
I've been over an hour trying everything I can think of.
 
Any suggestions.... I need the track space..
 
Thanks WG

Try selecting all the MIDI tracks, press Alt+8 Display events list.

Click on the View Down arrow and deselect the Notes at the top, what can you see now, any embedded patch changes?
