Korg Poly800/EX800 Users

Hello, all,
I just unboxed my new Poly800II to find that the tuning slider, one of
the keys, and three directions of the joystick are all non-functioning
 (down is the only joystick direction that seems to have any impact).
There is also a key that seems to have a problem with its contact, and
kind of scratches when i play it.

I have already contacted the guy who sold it to me and he says he'll
make it right, because it was working before he sent it. So that
part's cool.

My questions are mainly in second-guessing myself, and i wanted some
verification of the severity (or possibly even existence) of the
problems. The joystick bend (side-to-side) should be very pronounced
in ALL modes of operation, right? Moving it up should have an effect
in ALL modes, too, right? Adjustment of the tuning slider should be
very noticable, once again, in ALL modes of operation, right? And as
for the two keys with problems (one not working and one scratchy
sounding), is there a cleaning that needs to be done with these normally?

I've twiddled with a bunch of parameters to try to get the joystick up
and side directions to work to no avail, and i've played with the
tuning slider and can hear NOTHING CHANGING when i move it.

If anyone could give me some input, i'd appreciate it. My email is
jonsmith@...

let me know what you think, and thank you,
jon

the pitch bend of the joystick is only affected by the
slider that says bend next to it. The VCF and VCO
settings are program dependent. I guess I lucked out,
the one I got from EBAY is flawless. But I wish I had
a mkII!

actually that is incorrect, up is LFO to VCF and down
is LFO to VCO, right and left are pitch bend.

actually that is incorrect, up is LFO to VCF and down is LFO to VCO, right and left are pitch bend. actually, you re wrong too. up is lfo to DCO, not VCO.

I'm sorry, but you got it all wrong. The "oscillators" are simply a
single chip digital 8-channel tone generator (MSM5232RS in the service
manual). It was used in a lot of arcade games, too. 

Since everything in the Poly-800 is digitally controlled, why do you
think they didn't call the VCF "DCF" while they were at it? 

Best regards,
Philip Linde

> actually, you're wrong too. up is lfo to DCO, not VCO. the
oscillators are analog but digitally controlled, which gives them
their great stability. down is lfo to VCF, and left is pitch down and
obviously right is pitch up.

5th, i found that mine has to be set just above "9" or else it goes a
little flat when down and a little sharp when up.
