looking back at your original post, asking after arranger modules, the XP is probably closest in sound quality to the PA800, but it would be very close between it and the midjay/other ketron modules, if not a tie!!! to be honest the PA800 is really is good as it gets when it comes to arranger features and sounds, and imo, not matched by any current module..(i have owned the XP and a Midjay but got rid of both of them because i thought i could get something better...does NOT always work let me tell you!!!!) i currently own an sd1+, BUT if the pa800 had 76 keys and/or a different feel for the keys, too "synthy" for me, it would be on my keyboard stand now...fwiw and i know OT, but i am keenly awaiting the arrival of the pa2x in Oz.
