Hail X1 users!
I've run this 9000 up and down the block a few hundred times, and It's a "GOOD SECOND" The sounds and patterns on the X1 win big time. I stated that the Yamaha had alot going for it, and it does! If there was no X1, the 9000 would be the champ of all I've seen so far. The user interface is just wonderful, and the gingerbread features are terrific! Too bad, for me - it comes down to function & sound. The 126 note polyphony is a scam. It uses up notes faster than any of the old 64 note synths I've used, and even worse than a few 32 note ones! Keep your X1's folks, don't fall for the hype - it just isn't worth it. The X1 is a better all around package, if you care about sound, and variety, and "hipness" of styles!
