Thanks all, it's a bit rough round the edges, but good for todays purpose.
I'm going to try and make a fun educationalish music game out of it, compatible with an external piano keyboard. Haven't actually looked into the how exactly, but I know it's possible for Flash to communicate with external ports. Tips on that welcome!
Also looking forward to try me some, probably horrible, random music composition. I found an interesting looking book on the subject as well, so it won't be for lack of trying. It should be an excellent read after Godel Escher Bach too (which I raved about some time ago) as I was surprised to learn the books even reference eachother while I found this book through a wholly unrelated route!

Awesome! My first plan was to use the main theme song, but it would've been hell to write the score.
I'll see you though and raise you +5 nerdiness!

Rox dude, that shivers me timbers!
