Like Alecio, I am always looking for that perfect keyboard - great sounds, great action, not TOO big or heavy, fun to play, etc. I almost thought I had achieved the holy grail with the Yamaha S-90 (yeah, not a workstation, but I'm only concerned with live performance here). Great action, great sounds, best piano sample,etc. But one really annoying drawback. When you change sounds on the fly, there is an obvious and annoying interval of silence when the previous sound cuts off abruptly and the new sound loads. ARRGGGHHH! Thanks for letting me vent!
