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!!
