I don't know, I think the top MIDI tracks of all time would have to go to Final Fantasy VII over Doom.

So wait, that's a 2 gig MIDI sample set? I've heard about how those things are sampled sometimes for digital pianos. Something like they sample each note and like each overtone and harmonic of the note in seperate samples. They they are overlaid in real time. That or they sample each note for each of like 16 different dynamic levels. I forget the jargon that the sales man threw at me, but that digital piano I tried sounded damn good. Too bad speakers can't replicate the feeling of a piano; leaving us piano players totally unsatasfied.
