Hi Vic83,
I am a little confused at your last post.
Could you please clarify a few points.
You say that the OS for the E500OR can be
fixed by a nice Update by Roland. Does this
update actually exist? (If it doesn't, I doubt Roland would update a OS for a discontinued keyboard).

I realize that the G1000/EM2000 do not
have the complete oriental sound soundset
of the E500OR. Why the heck Roland doesn't
come up with a replacement for the E500OR,
(or at least a JV/SRX expansion card)is beyond me.
You had mentioned in another post that
the "EM50 OR" has ALL the oriental sounds
and drumkits of the "E500 OR". Is this correct?

Sammer,
If you are considering the GEM WK2OR,
I would suggest you listen to it on a
quality sound system. The sound quality
is definately inferior to the Roland boards.
I recently compared the "GEM PK5 OR" to the
"Yamaha PSR-550", and the Yamaha absolutely
SOUNDS much better than the GEM. The arabic
kit on the Yamaha actually sounds good too.
I liked it better than the two arabic kits on
the Korg PA-80.(However,PSR-550 has a lously "Riq tremelo" and the "zagruda stop" is not as
good as the GEM's).
The WK2OR
has the identical oriental soundset and
drumkit of the PK5OR. If you are considering
GEM, look at the WK6SE and WK8SE. Both these
boards have higher sound quality,from what
I have heard,than the WK2OR and PK5OR.
I hope this helps.
