Hi guys,
first time post to this group, so hello to all of you. I recently bought a used OB-Xa for a quite reasonable price and face the following
problem:
All controls on the surface work fine except the LFO Rate. The depth controls for Pitch/Filter and PWM, however show a change to the destination, but in a static way. The LFO isn't oscillating.
Can someone give me a hint of what could be wrong, or where to start investigating

Cheers,
Stephan
