Just one word of warning:
In case you copy code from non-sequencer, make sure to test it. I played
with it today, played with scales, and after I reverted to the initial
"Major" it started to more or less randomly not play notes. Well, I
think there was a pattern to it, but anyway, it seems to be buggy
somewhere around that code.
