Korg Poly800/EX800 Users

I have forgotten to introduce myself to the group..

My name is Aaron and i have been doing electronic music for over 10 
years. My studio now consists of:
 
synths: Roland Jx8p, Yamaha DX7, Korg PolySix, Korg Poly800, Ensoniq 
ESQ-1, Oberheim Matrix 1000, Sequencial Prophet 600.

Computer: mac G4 dual 450, 70gb Hard Drive, 448 RAM, Cubase VST5, 
VST instruments and effects (ProFive, PPG, Model E, Jx10, Battery, Attack, 
Absynth)

Studio Gear: Behringer 2004 Eurorack mixer, Midiman 2x2 midi interface, 
Electrix FilterFactory, Behringer Virtualizer Pro, Zoom 1204, Equitek studio 
mic, Danelectro Danecho, Fabtone.

Gutiars: Yamaha accustic, Fender Jag-Stang, Fender Jazzbass.

There is something about my Poly8 that i just love and try to find a place in 
most songs for it. I have this continuing desire to mod and tweak it. Maybe 
cuz the casing is so cheap feeling and it just seems like it doesn't matter if i 
hurt it. Anyway i have added Filt Cutoff and Q knobs to the front and just pu 
the battery in it (it must be an early MK1), the power source has probs too, i 
took it to a repair place but they couldn't fix it, so i just soldered a wall wart 
to the main batter connection. Works fine.

Hear is my question. The knobs work fine, but they only make an audible 
change to the filters from about 50%-100% opened up.. the rest of the range 
does nothing. Is there something i can do to make them sweep all the way 
across their range?

other question: That firmware problem is a real pain, it wipes half my presets 
when i go into Cubase... Is there a work around for this or do i just need to 
get a new Poly800?

Thanks in advance.

if anyone has other mods that they have performed or have ideas for some .. 
let me know..!

I had the same problem with the pots as well for these mods, If you 
take a look at the pots you removed they will indicate what they were 
ie 100k,5k or 1m etc. Let me know if you dont have them and i'll 
check my records
You should try to match them if you can but it can take some mucking 
around, i'm no expert but if you have put say a 200k pot on what was 
originally a 100k pot you most likely wont get any change for a lot 
of the sweep. Also muck around with both log and linnear pots, i know 
volume pots are always log but on some of my mods i used linnear 
because i liked the effect over log pots. Just muck around, you cant 
do much harm and i tested with cheaper pots before getting some nice 
ceramic ones for the final job.
