DRM files from musescore 2 to musescore 3
I've made some drm files in Musescore 2 to define the notes/sounds of some percussion instruments. When I try to use these files in Musescore 3 I get and error message:
Drumset file too old
! MuseScore may not be able to load this file
When I press IGNORE, the file is loaded, but one or another note is missing or is wrong.
Is there a way to update my DRM files?
Or may be I could edit them with a askii editor if I knew what I have to change.
