Dave, if I were you, I would keep the S-950 and get rid of the Korg. Forget the key feel stuff - it really doesn't hamper your playing ability at all. You know the OS like the back of your hand, the sounds are phenomenal, the styles are fabulous, and you can use it with an outboard vocal processor and have the best of all worlds. If it helps, find a couple strands of red hair and tactfully place them on the display where they can be seen, then you'll forget about the key feel thing.

Good Luck,

Gary
