SeP Laboratory Vocoder

Owners of such equipment! Reply plz!

The owner of this exhibit is a friend of mine. With his permission, I will post photos and some information:

During last 3 years we had some untypical, lesser known gear like analog drumboxes, analog accompaniament machines or built-in organ solosynths but there was always some info about manufacturer.

This SeP Vocoder is totally unknown. I don't know, maybe it was some kind of prototype for never launched project…

This vocoder is mysterious. Really. I have it from friend who bought it 5 years ago in Germany. But I'm not sure about its origin. 

On the net there's no info about it...
