I have a automatic accordion here that plays MIDI files. The music files have been lost so new music files are needed for the accordion to play again. Here is the scale it plays; only 22 notes:

D,D#,E,F,F#,G,G#,A,A#,B,C,C#,D,D#,E,F,F#,G,G#,A,B,C

It is kind of an odd thing that Alan Pell made for my customer.  We are hoping to find a composer that can supply us with music.

Thanks,
