Had to chime in here, for I own an EXR7s.
Pros:
Unparalleld 76 note keybed - the very best. Not cheesy
Speakers - awesome, despite what the specs show
Pianos - great - typical Roland
Sax - best on the market
Organs - good enough - nice leslie with the joystick
Guitars - if I knew how to play a guitar on a keyboard, I could comment more.
Drums - awesome
FX - rich and powerful, like the VA
Styles - onboard, excellent - accepts (3) different formats that load in quick and to flash
Sequencer - used to be a bid deal, but no more for me
SMF - good
Cover - haven't used
D-beam - is very useful, especially to stop/start style
Stle variations - (3) levels kind of neat, the different genres are strange though
Build - a tank, but lightweight for a 76
Cons:
Navigation - multiple pages, no easy way to access sounds/styles as mentioned by Fran
Style variations - only 2, bummer
Price - I got mine for a steal
Conclusion: If I were playing live, I'd pass on this one. For anything else and to play with styles, it's very good.
