Nick, maybe you're not a singer, but you don't mention the VH. Any thoughts on that feature? Good to see that the drum mapping has been addressed - that was always a drawback for me.

I don't know for sure but, people have told me VH2 on the s950/s970 is the same ..I wonder if the new HD reverbs improve the Voc Mic processor also?

The harmonizer actually works well. There is still a perceptible, though small, glitch if you engage, or disengage, the VH while singing a note. I doubt a live audience would hear it, but it's there. Turn it on and of when you take a breath and it's o.k. I don't have to worry about that with Korg or Ketron.
It does not seem to distort as easily as previous models. Everything seems the same, but it sounds better. Maybe the new reverb, as DNJ suggested....
I may start using the Harmony M again, but not because the S970 vocals aren't good. Because I want to have a footswitch to turn harmony on/off, one for sustain, and one for break/fill. The PSR only has two switches. Using the Harmony M would free up one of those for the other uses.

Another thought...maybe my primary gripe with the VH on the S970 is that there is no pilot light to tell me if it is on.
I might end a song with it on then announce the next song. The VH does not sound when the style isn't running, so I forget it's on. I start the next song and it is on. Have to turn it off. Just another little thing that makes a difference.

DON I AGREE IT'S THE SIMPLE THINGS THAT SET A KB APART,....
MAYBE THE S990 WILL HAVE THAT LITTLE LIGHT IMPLEMENTED on deck!...WE'LL SEE...?
ALL THEY HAVE TO DO IS "LISTEN" TO PLAYERS NEEDS..

I agree with much that’s been said about the S970. I moved up from the previous model and glad I did. It sounds better, plays better, and the vocal harmony works better. I’ll jump for the latest model, even if the increments are minimal. Newer is better and improved in most cases. Got to keep a competitive edge around here.

I've been using one of the active knobs to control Harmony on and off. Works well for me.

Is there a list of functions the knobs can control on the S970

Yes there is. I'm using it for balance between right hand and styles, and to mute style parts.

good to know Don, every knob counts,...Can't wait..
