Yeah I'd love for us to make a piano version too. We haven't started it yet, but maybe it's percolating - I've been spending a ton of time on the piano lately. :)
Works with any (most?) midi keyboards. I use it with an M-Audio ProKeys 88 (weighted keys). It's an awesome program. You can load any .mid file in to it and select the instruments you want to play on keys, and have it display the sheet music along with the note cascade.
I cannot recommend this program enough, and the learning method in general. Synthesia and YouTube videos have been my sole learning method / teaching aid, and in the past 18 months I've learned to play a handful of short pieces well enough to put a huge grin on my face.
