Where are the MIDI files that are used in the Ballad-mini folder? For example, the first song “Ballad 2” uses an intro file “Ballad Fill 9.bbt” but that file is not on my disk that I can see. Where are all these midi files for this folder?
If they aren’t in the midi_sources folder, I am guessing that because they might have been part of the BeatBuddy (BB) Mini or Mini 2 that they were not included in the midi_sources folder (for the full-size BeatBuddy (BB)).
If you want to edit the MIDI files, you can try your hand at exporting to MIDI those sections that you need. No guarantee that the files you export can be edited though.
You can copy and paste the song sections and reuse them in a different beat or song.
