Hi

For my easter vacation i forgot my window open and when I got back the whole room included my Korg D1600mkII was covered in dust. The faders took it really bad, the have become really hard to and I'm anxious to use them now because it feels like I'm going to break something when I use them.

I have fixed the problem, I'd say, 40% by spraying WD40 on small pieces of "kitchen paper" and folded it to suitable sizes and pressed it down and scrubbed (pun intended) back and forth. I have also opened it and realized that there is isnt any good chance of fixing this because it's not really user servicable inside.....


so, how should I proceed? should I spray more WD40, or even just spray it down the faders, or should I service it (for money I dont have), or should I just dont care with the risk that the faders might loose contact later on because of higher friction and stone dust (dust just as evil as nuclear and asbestos dust, that is)?

the faders are non automated (phew!!), and completely digital.


hope ya'll can help me, this really sucks.

First off don't ever *scrub* the internals of faders. Treat them with infinite
care and a light touch.

Get some Q-tips for this btw.

WD40 isn't treally the right stuff but it could have been a lot worse. Scott D
and others will suggest something better you can get over there.

my suggestion it to contact Korg service for their recommendation on
cleaning this particular part.

baring a factory recommendation to the contrary, use a lubricating cleaner
like Caig De-Oxit.

if it really gritty the fader will need to be disassembled (if possible)
cleaned and a small dab of non-hardening grease on the slide mechanism (not
the resistive surface).

This is bad. It's bad because WD40 turns into goo when it evaporates.
It leaves behind sticky gummy residue that attracts dust.

so, how should I proceed? should I spray more WD40, or even just spray
it down the faders, or should I service it (for money I dont have), or

You can't flush them out with alcohol at this point, because those faders
are basically sealed and have internal lubrication. You could TRY and
flush them out with Cailube. At worst you'll remove the lubrication on
the top of the sliders.

I think these consoles just use standard analogue potentiometer faders,
and they aren't the nice kind with the rails and the seperate element
but the cheap kind where the top of the fader can holds the slider in
place as it moves up and back (and therefore the underside of the top
of the fader can has some thick grease on it that you don't want
to remove.

the faders are non automated (phew!!), and completely digital.

I think they are just faders that drive a little A/D. I don't think they
are actual digital encoders on this thing. If they are encoders you can
probably disassemble them and clean the individual parts with Q-tips.

hope ya'll can help me, this really sucks.

When it happens again, first try the flush with compressed air and avoid
the WD-40. The truth is, though, that since this sort of fader design
has a greased surface inside the fader, when dust gets into the thing
it will get stuck in the grease and it will begin to feel gritty.

This is admittedly better than getting stuck on the resistive surface
and wearing it down, though.

Hey guys, I'm so incredible happy for your sharing knowledge, sorry for not replying sooner (I've had 3 different concerts in four days now....)

Anyway, I'm really ****ed off at Korg because of making me buying this D1600mkII and then discontinued the product without releasing any basic system upgrade to fix the most basic bugs (grrrrrrrrrrrrr) so I havent contacted them. I shall though, the vacation's soon here, and then I've got time and are dependent on the thing....

Ok, I think I've gotten the views and help of you to proceed now, thank you so much. My plan is to get one of those silicon based stuff, use one of those electronic cleaner sprays that evaporates and then spraying on a silicone based one. before that contacting korg (but I have no hope of getting any help what so ever from them... grrrr

thanks again.
