I'm with Diki.., I'll be waiting for the rack.

Nick, you'll have a blast with the XS. It will blow the Tyros 2 away with the styles of music you like to do. Plus you'll have some familiar voices on the XS, and a MUCH better recording platform. You'll be able to use the arps in arranger fashion, and even write your own (again, that should work very well for you after owning the Tyros 2).

The OS will be completely different though. The XS will be really indepth. Just take your time with it and be sure to post any questions you have at Motifator.com They'll answer any question you got--PLUS--Yamaha reps themselves will respond to questions on that site!
