Wow!
Gottschalk: Grande Tarantelle, Op. 67 (Espadero's solo-piano arrangement)
This person taught Claude to understand braille music from a .BRF file and convert it to midi. It makes sense since I'm sure the braille music code is available to find, but still it's the type of thing that would not have been possible a year ago. The source is here. Could be another cool way to create music.
