If you had a S910 or previous model and now have a S950....
you can just load up your old style /reg and they will play fine BUT,.....I would strongly advise you to take every style & reg setup of the old KB and change the styles for the ones with the same titles on the new S910 & add your OTS to it....many have different voicings, intros, endings, sounds, etc, .. and do sound much better balanced and Eq'd also,....yes it takes Hours on end but WELL WORTH THE EFFORT!!

I just spent 4 1/2 hours editing the S950 to get it where I need it to be for stage performances.......it's really amazing the fine job Yamaha has done revamping all these older styles,.... the S950 does have it's faults BUT,.. the Good definitely outweighs the Bad.

It's all coming back using the S950 gig after gig after a 3 month stay away using my Korg Pa3x..each performance brings you closer to doing it "second nature", .... both are solid arrangers.
Off to another Mardi Gras luncheon today,....
have a good one everyone!

It's amazing what Yamaha has done to revamp the Styles on the S950 vs the S900/910 etc, clarity, style parts,
sound assignments & overall sonic fidelity is very much improved,....now that I have had some time to really get in to it mostly what I have done is simply switch many of the older factory styles for the newer S950 ones....then go into the style creator and make some changes to style part Volumes for variations, Intros, Endings where called for, EQ here and there, & re-save...change some OTS sounds for newer ones eg:
Whiter Shade Organ, etc...I made a few tweaks to the VH2 harmonizer but its still no where the quality of a TC Helicon,..but in time I will try to really dissect it and dig into the settings to make it usable.... I am happy with the on-board FX settings rev/short slap back delay for my main vocals....after 35+ gigs since I have the S950 each time I make changes on the fly to get it just right for my needs & that is working out very well even with some workarounds... The audio Play button from the MFD screen is a nice addition also so you don't have to open the Audio player to use just select and play from the MFD screen......the speakers are much improved also.

Are you tweaking using the onboard speakers or running thru larger speakers and at volumes similar to gig volumes?

Eddie I always set up my powered speakers when I do anything on the keyboard don't want any surprises on stage that's the only way to do it no headphones or on board speakers when tweaking sounds.........been at this game too long.
