Korg Trident Key problem

Korg Trident Key problem

2013-02-22 by eithne6194

I've got a broken 'd' key on my trident and want to take it off so I can repair it (or replace if I get another one). 

I can pull the key backwards but the hook on the underside of the key doesn't seem to pull back far enough to get released. I've been gentle with it so far as I don't want to make things worse.

Has anyone got any tips on getting the keys off a Korg Trident.

I've took keys off many keyboards in the past (Ensonique, yamaha and roland) but this looks a bit trickier than those ... thanks

I've done M1 and O1Ws before, and if it's the same then you need to push the key firmly backwards to bend the metal springy strip under the key slightly more than normal, then it will clear the hook.  Backwards as in, if you're playing the keyboard then push the key via the front tip horizontally away from you.  I recall that it was fiddly because I had to apply quite a bit of pressure.  The spring is a thin flat metal strip about a few inches long which clips beneath the key, and it is bent along it's length just a bit extra to allow the key to be removed.  Hope this helps, of course, the Trident could be entirely different.

Mike.

P.S. I could be thinking the wrong way, could be push forwards, same thing applies though with the spring...  It's been a long time!  But I will be doing it again soon because I have a broken key on my Korg Ds8 to replace soon.  Mike.

The tolerances of the Trident keys are very small.

The "hook" on the underside is actually smaller than the one on the upper
side. It will pass the metal frame but may require a bit more nudging. I
don't know if your metal frame has also the adhesive tape on top of it?
If you look at it very carefully you'll notice that the key simply cannot
move any more toward the front since it already hits the other side of the
metal frame. So this is the only way - pull it toward the fron as far as
possible and then somehow try to wiggle it out of the keybed.

The Trident keyboard is unlike most of the other keyboards from later era
Korg (Polysix and onwards) because it uses metal contacts. I believe the
MS-20 has a similar construction.
