I haven't seen much discussion on exactly what application Sean has, and I think that's the most important topic when comparing keyboards. The 9000 Pro seems meant to be the central or only keyboard in a live "one-man-band" act. It's music database exhibits it's target market with setups clearly designed for live performance of songs from Proud Mary to the Chicken Dance... it's a "wedding-singer keyboard". I think that point was missed in the magazine reviews of the 9000 Pro... when studio musicians reviewed the 9000 Pro, they did so with their own applications in mind. The reviewer for Keyboard magazine used the 9000 Pro to sample and remix music for a tv commercial, which was her speciality. She really had no use for the music database so it wasn't mentioned in her review, yet it's one of the 9000 Pro's strongest features IF you have an application for it. The 9000 Pro is overpriced if you don't use all it's features, but it's a bargain if you use everything it potentially offers as a one-man entertainment center. If you haven't seen a 9000 Pro, at least check out the more common PSR9000 which has many of the same basic features.
