Korg Poly800/EX800 Users

I just got a Poly-800 today for a HANDSHAKE when my bassist, who
works for a local sound gear store called me to tell me to come get
the thing before it went to the dumpster. A customer had purchased a
new keyboard and brought in the old Poly synth to find a power supply
for it and decided to not mess with it and told them to do whatever
they wanted with it. I hope it works, still haven't put any V+ to it
to see if it's alive. If not, I may have some parts for you guys!
  After listening to the samples of the FM-800 mod, I was indeed
impressed. I wonder however, if the resolution of the tones would be
improved if one were to use the same value for pots, but using 10-turn
pots instead. They are freaking expensive ($15 to $25 each) plus they
are generally twice as long in the "housing" but wouldn't it be sweet
to be able to smoothly and with 10 times the resolution sweep across
the ranges? I have a few lying around, maybe a couple are the right
values I hope. I am already having visions of 555 timer IC's being
used to assign programable variable sweeps that wouldn't require the
knob-turning. I'm just getting started! I might add. the Arp 2600 was
my first synth!
 News at 11, when ever that is...

BTW, Bob Moog (Rest his soul)would be proud of you all!

based on that story, i'd be *very* surprised if it doesn't work fine.

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

there's nothing wrong with using a multi-turn precision pot, but you'd 
give up a lot of the tweaking insanity that's useful for techno. depending 
on what kind of music you plan to make with it, it's possible that you'd 
be better off with a multi-turn pot. as a matter of design, everything is 
a trade-off...

using a 3/4 turn standard pot works best for most people who are using 
poly800s for some kind of techno/house/electronica/etc. if your name is 
mark snow, and you'll be scoring some x-files soundtracks, then a 
multi-turn pot would be probably be better.
