Interval Problem with Micromoog -- Please Help

Hey.

I just bought a used micromoog and I am having a serious problem. The interval between each key is extremely off. It sounds like each half step is a whole step and each whole step is two hole steps. I am new to analog synths and have no idea what to do. Obviously, the fine tuning does not work enough.

Is it my settings or do I need to just need to adjust the tuning drastically? Or is my synth just defective? Has anyone had a similiar problem? Any help would be greatly appreciated.

Thanks.
