In theory you should be able to convert sheet music from a PDF to MIDI with something like this (I did a quick Google search)

Once you have a MIDI[1] file, you can do a lot of interesting things with your music, such as generating or modifying notes with random values for pitch, velocity etc.

Never realized how easy it was to manipulate a midi file. You can even convert a midi file to csv. Perfect. Thanks!
