For MIDI Channel 10, each MIDI KEY number ("NOTE#") corresponds to a different drum sound, as shown below. While many current instruments also have additional sounds above or below the range show here, and may even have additional "kits" with variations of these sounds, only these sounds are supported by General MIDI Level 1 devices.

Note: There seems to be a bug in MuseScore 4, when re-importing a MIDI file that has been updated. If MuseScore seems to be playing notes that you recently updated, try closing MuseScore, opening it again, and importing the MIDI file again.
