I had the opportunity to play an MOX8 while in the Florida Keys - the piano sounds were absolutely awesome - probably the best of any synth I've heard. Of course, it helps if the guy playing the keyboard knows how to play the piano, which I DO NOT! When the guy that owned it played a bit of Floyd Kramer's Last Date, it was the best of the best performances - he was pretty amazing.

That said, I need more than that from my arranger, and while that MOX8 sounded great, it was a pain to work through the settings to get it ready for the next song. Lots of buttons to push, and his dead time between songs approached 3 minutes when things were gelling. I like the ease of navigation I now enjoy with the S-950 and all the predecessor arrangers I've owned in the past.

Good Luck,

Gary
