Suddenly developed wrong drum sound

Howdy Lawrence,

Is this an original .mid file, or has it been opened and then saved/exported from another application?

The reasons I'm asking are that
(1) all the instrument patches are set to "001 acoustic grand piano" (except "Sorry", which has no notes) and
(2) some of what appear to be drum instrument staves are set for channel 11 rather than channel 10.

Do you have a .mid file that you know worked properly for your DGX prior to things going haywire again? If so, please attach one of those for comparison for me.

Perhaps if there are other Yamaha DGX users out there, you can chime in if any aspects of this conundrum ring a bell for you.

Thanks!
Sherry
