hi....

I'm interested in the Roland EA7. but naturally have a few ??s

keybed: Same as Juno DS or the FA series?
electric pianos: I usually love Roland EPs -- would these be on par with the ones in the FA?
effects: is there any realtime control over effects like reverb/delay?
audio input: can you incorporate the audio input into USB Audio recording? ie, is it possible to input guitar or saxophone and capture that along with the live keyboard playing?

thanks in advance for any and all insights....
