I like being able to run code under warnings (I am a module author), so adding this: 

  for (@f) { $_ = 0 unless defined }

[download]

is handy below the foreach in the code.

Also, I am a fan of Sean Burke's MIDI perl modules, so I prefer "As" and "Af" instead of "A#" and "AB". If you use these, you can talk directly to the MIDI modules without any needless parsing gymnastics. Also, putting #'s in qw() arrays breaks with warnings on.

Anyway, here are some questions:

1. Is there a name for "@f" that might give away what it stands for and holds? Variables named things like "f" are pretty frustrating.

2. What does ($n+$_)%12 represent?

3. What is (0,0,0,2,5,5,8,10)?

Maybe the Terhardt link describes this stuff somewhere, but... comments are really useful.
