What MD player are you using? Because I upgraded to Win 7 64-bit from Vista 64-bit and have Sonic Stage 4.3, and works perfectly with my MZ-M100...it won't with my older MZ-N707, which I know why that is. But I think with the M100 & M200, they may work flawlessly with Win 7.

Same here with the N707 that got me hooked, which led to my MZ-M100...shame they took the charging cradle away for the M100 , actually trying to find a home for the N707.
