Dave, I certainly wouldn't expect you to switch from the great system you already have...it's just that the Tyros has finally got the harmony thing right.

Every vocalizer/harmonizer will have it's smaller details that will make each one appeal to a different type of singer, or type of music being sung.

Personally, I'm pleased to see the Yamaha VH come of age with the Tyros4.

I'll look forward to your impressions of the VH-2 when you get a chance to demo a Tyros4.
