Hi Guys.
Today I received an Oxygen 49 keyboard with the pitch bend control wheel not working as it should. After tuning it up or down, it won’t return to its initial position at first. I have to pull it down and let go for it to jump to the initial tone. When I move it up and let go it still stays out of tune.
This also happens when I give it a small perpendicular push. It detunes about half a semitone below the normal.
Has anyone seen this before?
Thanks in advance
