Just two years after letting me build my dream home theater, my wife let me buy a Kurzweil Mark 12i digital piano. We drove up to Chicago to pick it up this past weekend. It sounds awesome. It makes me sound better than I am. I'm finding that a lot of the MIDI files on the Internet (the free ones) are either very poorly produced or don't work at all on the Mark 12i. Does anyone know of a good source for MIDI's. According to the Kurzweil web site, it sould be able to play the General Midi format, Yamaha PianoSoft and Disk Orchestra libraries, as well as the PianoDisc library. Thanks!
