In the real early days of Yamaha keyboards and MIDI one had to remap the drums going to the Yamaha keyboard. Yamaha used channel 16 not channel 10 for drums.

I don’t know if this could be a part of your issue but what I’m reading I doubt it.

This is going back some time but it was an issue I used to have to deal with.
