File Format

The following is a quick explanation of the .fmd file format
(I'm still not sure about this extension, but whatever)

Currently, the player reads 12 bytes into the file, runs a
key on/off subroutine, and waits an amount of time specified
in the program itself.  Then it reads another 12 bytes,
repeating the process.

Bytes 1,3,5,7,9, and 11 specify the note to play
Bytes 2,4,6,8,10, and 12 are either Key ON(1), Key OFF(2),
or it is ignored
