Makes no sense.

My workflow would be, given the above

1. Start song verify odd noises are there.
2. Mute 1st Track. Repeat. Continue until you mute each track except the drum track.
3. Put the midi drum track on the screen in editable notation and play and watch for what is happening.

Because the midi drum track is supposed to regenerate based on the midi pattern every time play is pressed the only explanation is that something is wrong with the style file.

Other than that some spurious data is on Ch10 some other place.

Also verify that there is NO .wav file of the same name in the folder.

Also verify that there are no sounds happening if the ketron is shut off.
