(Let me start by saying that I am a guitar player and don't know a ton about synths so feel free to correct my terminology if I get some things wrong.) This is a vintage synthesizer from Italy. It powers up and all the keys produce notes, it seemed in tune with itself when chords were played. There is a pitch control near the pitch slider thingy that change the pitch when moved, I would guess that the pitch wheel could dial it in to a modern tuner, or wherever else you wanted to go. There is a multi position octave selector switch near the bender bar that changes the overall octave of the synth up and down.

I messed around with this thing for about half an hour, and the knobs & sliders seemed to work, with one notable exception* - rates and octaves change, timbres change, the sounds can be modified.* The one thing I couldn't get to work was the little pitch bender bar. It may work, and I didn't have it engaged? This thing has so many controls that I wasn't sure what I was doing. There may have been other things that don't work, but it seemed like most of the controls were functional. The only thing I noticed that was definitely missing was the top slider for OSC. 1 on the left hand side of the keyboard. You can see this section in one of the pictures. The controls seemed pretty clean, not super scratchy.

Cosmetically this thing is in pretty good shape. The case seems to have kept it pretty nice over the years. Some old tape here and there, normal wear from use you'd see on a vintage instrument, but nothing serious. The case has some nicks and scrapes but it is solid as well. Will need a new handle. Pictures should tell the story, condition wise. "
