HI Jan

Shame that did not work for you I guess the os is slightly different for the 700 cvp as they have touch screens .
Yes the drums use ch 10

The nearest pat file on BIAB would be the Yamaha Tyros this should give you the correct drum maps for the cvp and most of your cvp upper bank voices .
You will of course have to select them via the BIAB mixer. Once the pat file is loaded use the down arrow at the rh end of the mixer track to make you voice and drum selections on the respective parts,
