MicroKontrol Joystick problems

[Monstamac]

Hi all.

Its 2021 and I cant find a solution to this in any forum and I can see im not alone.

My joystick never returns to zero even though it springs back to the centre. Pitch bend is roughly +7 afterwards and mod ( Y) is around 40.

There is no problem with the springs, it is centred. It needs to be recalibrated but I cant find any reference on how to do this even though this is something available on other Korg keyboards.

Has anyone found a solution,???

Im going to have to stop using this keyboard and theres nothing as good out there in any case which is a terrible shame and waste.
