OctaMED, hehe, wicked.
You must be my age Cappie (or a twin! 8O ), as I was doing exactly the same at 12yrs old in '92, with an Amiga500+ using OctaMED. I'm sure half the stuff I did then sounded better than the stuff I come up with now, lol.
(Cubase, Logic, etc for drum-programming? Pah! Can't beat Tracker-esque interfaces for drums. I use Renoise now.)
