hi AJ, I don't know if the Tyros voice 'editing capabilities' themselves are more 'sophisticated' than say on the 9000pro, but the fact that you can edit & audition them via your PC computer's CRT/LCD screen instead of on the Tyros itself (via LCD screen sub menus) is what makes the Tyros 'voice' editing cabilities so much more CONVENIENT and USER FRIENDLY.

Gerbo, can you please tell us exactly WHAT 'voice editing' parameters are supported in the Tyros "Voice Editor" program included with the Tyros CD Rom? Thanks. - Scott
