OB-x8 Pitch Wheel Issues

OB-x8 Pitch Wheel Issues
« on: February 07, 2024, 12:23:22 PM »
I bought my OB-x8 synth in 2022 around October month. But 6 months ago I started having issues with the pitch and mod wheel. whenever I touch it, there seems to be modulation constantly  on all patches - and the pitch wheel works with up to 1.5 seconds of delay.

i have tried to update the firmware and calibrated the synth many times, but it doesn't fix the issue. A full calibration only fixes the constantly modulation, until you touch the mod of pitch wheel again. Then the synth goes back to constantly pitch modulating all patches and notes while playing.

before this issue, I also had other issues, like wierd noises while turning the filter  and ADSR knobs. but in October 2023 I had the whole synth sent to the Oberheim service center to fix. unfortunately they just sent the synth back after 1.5 months without fixing the pitch wheel issue but just fixing the noise...

does anyone know about this issue or how I can fix it? I use the Synth everyday, since its very important for me - right now I just can't use the pitch and mod wheel because it will screw everything up...

does anyone know anything?

Hi! What was the support ticket number? Was the synth sent to San Francisco (it's a very long repair time for us)?

Have you tried calibrating the levers using the global menu Lever Calibration routine?

And another, did you reset globals after firmware update? Not doing so can cause all sorts of weirdness.

Oh yes thanks" it worked. I didn't knew I had to calibrate the levers by holding the pitch wheels down etc.

thanks!

Ah I think the danish retailer have sent it to a private repair house - Not Oberheim service center in San Francisco.
