This version has triplets, but is much too fast to be played on a music box. I tried to use photoshop to scale it down so that it would use less paper and have notes punched in between the lines, but it became too complicated since the PDF breaks the strip into sections instead of having a continuous strip. Hopefully, I can find a good solution for songs with triplets in MBM soon!
Truthfully, if I was disciplined enough I could do the math to downsize this arrangement; I've done it before. But it takes a lot of time and effort, and I'm hoping I can find a good solution for others, too.
