Way off topic here, but who cares...
I think the "performance"
might be copyrightable.
By that I mean the actual pitch, time, velocity and length of each "note".
They're not really notes, are they?
Its a midi sequence, its NOT music, or is it?
It's really just a string of on/off, where, how much; isn't it?
Just my nickel 98.
