I must agree with Dave. The 2000 is a great keyboard and the "bugs" would not be significant if it weren't for the deception and attitude involved.
The Vocal Harmonizer problem only affects a couple of "gimmick" settings--Karaoke Girl and Speedy Mouse. They just happen to be particularly important to me.
None of the other keyboards beside Yamaha even offer these settings on internal harmonizers. Point is if I'd known it didn't work correctly and that it wasn't easily fixable (as it would be in Flash Rom) then I would most likely have bought a 9000 Pro, despite the weight.
I would gladly have paid more money to get the keyboard AS ADVERTISED.
