Korg Poly800/EX800 Users

Hi Poly-Family,

I've seen some of the members have their program write switch put on
top of their Poly 800's panell. I want to do that mod too because it's
so much easier than having to reach around the back of the Poly. 
Can anybody tell me where to solder the switch for this? What kind of
switch do I need?

I tried a 3 pin switch and soldered it this way:

oooooo
ooo++o

But this didn't do anything. Do I need a 6 pin switch instead?

Thanks for your help,
Flo

===============================

it depends on how the switch is wired. you don't need more pines, you need 
a diagram of what the pins do... or an electrical meter to figure out what 
the pins do.

Hey Atom,

Thanks for your post. I think I found out what I needed by measusing
it with my electrical meter. I'm gonna post it here anyway for all who
are intereted.

The following pins are connected if program write switch is set to
enabled. (For orientation - the Out L and Out R head to the right side
up. I look at the program write switch from below.)

ooo++o
ooo++o

If the Program write switch is set to disabled the following pins are
connected:

oooo++
oooo++

My thoughts were that if I put another switch between the connected
pins I could remotely switch the program write switch on/off.Only my
mistake was that I soldered it this way:

oooooo
ooo++o
          ||      _/_
          ||    |___|
          ||___|||
          |____|

(I hope somebody can understand this-the box in the bottom is supposed
to be a 3pin on/off switch)

And that left two pins still connected to each other - so the
connection wasn't interupted. Now I'm going to try a 6 pin on/off
switch so that I can cut the connection completely. I think that
should do it.

Cheers :)
