I agree with DNJ. The VH feature is one of the most important to me, since the majority of my tunes involve vocals. Wish someone with the SX 900 would give it a try and report; or, get a friend, or someone who sings, and create a demo for us. Think about it----how many of the pro guys with Yamaha sing? Rarely do you see that in the promotional videos. When a new arranger appears, why can’t Yamaha (just once) provide us with a talented player/singer, who can show us all the various VH options and potential uses before we upgrade, or purchase?
