A problem has developed where the pitch stick has a constant offset on it. Select a patch, plays ok and in tune, but slightly move the pitch stick and allow it to spring back, patch plays out of tune very slightly. Recall patch, back in tune until pitch stick moved again.

Any ideas? Cant find anything on calibrating the stick, is it optical or just a pot?

Neither. It is a metal strip with a pressure sensitive strip on it. Bending it generates those values.

I don't think you can calibrate your pitch stick, but I'm not completely sure. Maybe some tech guy with the right info (from Clavia) might be able to. However, these things do wear down with use and need to be replaced after a they've seen a lot of use.

I'd contact the distributor for Nord products in the UK - they can advise you on how to proceed. There's a link to the distributors near the top-right when viewing the Nord website. You can also contact Clavia via the support form on the Nord website; they'll either answer your question or send it on to the appropriate distributor, in case they think the distributor is better equiped to help you.

The post below has some nice pictures of the pitch stick.

Hi Julian,

Those parts are subject to wear and tear over time and may eventually need to be replaced. Sounds like your time has come...

Your UK distributor should be able to advise you on possible service shops and/or parts supply.

On my fourth G2X pitch stick after the same problems JulianW documented.

This one has worked for alot longer than the previous. I was always concerned that the sticks ever appeared to be centered physically in the panel opening...and the extra travel distance caused the stick to become fatigued over time. My correspondence with Nord assured me that this is not an issue...but just for sense of false security, I trimmed a spare rubber foot from my junk drawer and stuck it to the wide side of the wooden stick. Maybe it is just a coincidence that 3 sticks failed in a row...but I am very happy to have a useable G2X fir longer than a few weeks at a time.

I've read lots of broken stick, but three on a row... Obviously it is not a durable design and wonder:

1. what is exactly the rubber foot, where do you put it?

And what for? to help return to the centre?

2. The transducer is most probably made of two strain gauges that when flexed they change a resistance.
If we knew what the values were, this could be replaced with a spring loaded stick of some kind.

In this link, post #10:

somebody suggests 2 possible RS Components stain gauges to replace them, but I would be extra careful about doing this without knowing what is the spec of the original part, and unfortunately there is no feedback on the suitability of the suggestions.

Mr. G - see gallery photos

I see the rubber piece in place and the stick out of centre. Thanks.
So why does the rubber help in this case? To prevent going too much to the left? Or to put the stick in a position where there is no bending? (Sorry I still do not understand well what is going on).

[Mr. Marko]

It keeps the stick from going too far left...as it stands, I get full travel for the pitch bend setting used for each patch.

IMO the stick will fatigue if it travels too far...this is not confirmed by anything except my belief after the problems with several pitch sticks before I used the rubber spacer to correct for the out of center-ness of the mount.
