Reissue Model D 3 Osc is going crazy

Hi!
Im not an synth expert at all, but I do know the 3 Osc can also be used as LFO, but do anyone know what’s going on here? I can’t get any sound out from 4’ and below and all wave shapes sounds crazy! Osc 1 and 2 sounds perfect.
I hope that its me that do someting wrong :wink:

Can someone help me out here? :smiley:

How long as this behaviour been happening?
Try disconnecting Osc 3 and using as LFO can you hear it triggering say frequency as you would expect?

All settings look OK. So I am afraid it is a hardware failure.

bizarre!

you could try calibrating it?
