One thing you may also notice is that the keybed on the Tyros is much firmer than the PSR S900. You might want to alter the touch to soft1 or soft2 setting, so that the instruments like sax will give you the full range of sound that you're looking for. Otherwise the way you have to really hammer the keys to get the full expression range out of the Sax may wind up with you feeling 'disappointed' in the sound, when in reality it's simply an adjustment to the amound of key pressure that's needed.. fortunately, this is easily changed in the settings area of this board. The downside of this is that OTHER instruments sound better with the "normal" keybed pressure setting.... so it's more "touchy" than the PSR S900, which isn't necessarily bad...
