Nope, not redundant. And I'm not walking slowly - I hope to have the first stab released tomorrow (we'll see:)

I don't plan on doing things the way Yamaha does. More the way band in a box does.

I eventually plan on making a style format that fits completely within the midi standard and can be edited with any midi editor. (There'll be a program to take plain .STYs and convert them.)

The idea is for a piano newb to find leadsheets, type em into a .txt file, find a random style that sounds good to them, and look at the style notes - picking them apart to figure out how to play the parts that look interesting (and still hearing the other parts).

Also, to be able to do things like, say, you're playing a melody from loud to soft... As you do the style playback's volume adjusts AS you play the melody, so it follows your "feel". That'll make it sound a lot less robotic. And other similar stuff.
