I have to admit the new Audio "COOL SWING" style is simply amazing sounding!.Tried it cold on stage last night. Gary is correct that there is definitely a sonic improvement difference in a Good Way from the S910. All my custom Reg/Styles loaded flawlessly from the S910 and aside from some very minor VOL adjustments, EQ, to some of the sounds/styles Up/Down it's a seamless inter-change from the S910 to S950. After three gigs so far I've been impressed to a point, ..still a few workarounds needed for MY needs and a few things I wish they would address in future models, eg: Keyfeel, MFD, VH2, Rear USB input & placement,...
But Overall a green-light so far.

To be continued.
