Pitch stick broken?..

Glad to see it's being taken care of, and I'm sorry to see the need even arise. But until we achieve 100% perfection in QC there will always be "some" issues... it's how we handle it that counts.

Best regards,

Jerry

Well, the word from the service centre is:

Three A/D-converters are broken.

Cost to replace: $1400...

I am in shock.

WOW! Holy crap. That is an eye opener for sure. I can understand your shock. How did it go from pitch bend to A/D converters? Not that I fully understand Oasys schematics, but I would think that you would have noticed other issues besides the pitch bend.

Tell them that is more than you want to spend and see if they could discount the work a little more.

I agree. What does it mean the converters are "broken": physically damaged? Are they on the mainboard maybe - so they want to replace the whole board? What is the relation between the pitch bender and the converters?

That quote is absurd. You could buy an entire new Korg keyboard for that price, which itself would include a whole bunch of A/D converters and far more expensive pieces ! Sure there is work to do to replace the chips on the PCB, but it isn't that much of an effort.

Seems pretty expensive to me too, and I've inquired about this. It may turn out to be justified for some reason, so I don't want to jump to any conclusions, but I'd hope that it would be less costly than that.

In re what A/Ds have to do with the joystick: the continuous controllers, including joystick, vector joystick, aftertouch, ribbon, foot pedal, and half damper, all generate analog signals. A/Ds are necessary to get those analog signals into the digital system. This applies to any digital synth, and even digitally-controlled analog synths.

Thank you for the info. In OASYS are they the same converters that are responsible for the audio signals?

They'll be different parts.

the pitch lever problem is my only gripes with korg products i too have a keyboard
a triton classic that pitch bend on its own when im playing & even when im not in
sequencer playback..i had always associated the problem with the zip drive mod
that i did to it, but i now see that the problem is more common than people realize.

also,.

i recently bought a use triton studio and it too have lever problem..tho, not as bad
as the classic when you push the y-axis away from you (modulation) the studio will
send pitchbend data as well without me playing pitchbend..i think the good people
at korg need to be made aware of this ongoing issue with the faulty pitchbend lever
cause it's making their high-end products soooo unreliable to play with live onstage

Using the V Synth GT or Nord Lead controls after using a Korg Triton family instrument (Triton, TR, Oasys) is quite a shock.

Better or worse?

The Roland and Clavia hardware is vastly superior in my experience. The same is true of the ribbon Yamaha use, which actually works. It doesn't double take or intermittently ignore you like the Korg ribbon does. It just works like using the mouse pad on my Macbook Pro.

In fairness the M3 modulation joystick seemed to be much improved.

Today, my Oasys came back from the service centre. This is what they did:

1. Three A/D-converters exchanged.

2. Broken conductive pathway on one of the circuit boards fixed.

3. Electrolytes in the PSU exchanged.

4. Three buttons exchanged.

5. General overview, cleaning of all contact surfaces and calibration.

Work hours: eight.

Total final cost: $1100.

Now, I am going to turn it on and see what happens..

I am just checking my watch. Oh yes, it is still the 21st century.

I suspect it will not work, because the costs suggest that a lawyer was inadvertently employed to perform the repair.

How long have you owned this instrument ?
