"The rack version of the VS is quite rare. This is serial # 354 and my understanding that only a few hundred of the rack version of this synth were ever produced."

Here's a short video showing some of the reactions we got when people put the headphones on and started making their own beats with beatseqr and steppa. Hope to see you in New York 2010!"
via this auction "Realistic/Moog Concertmate MG-1, model 42-4000, serial #4256 written in marker. SUPER clean and well taken care of. Was owned by one older fella up until this point; it sat in his hobby room since the mid 80's being played occasionally. These are a Moog synth that were made for Realistic/Radio Shack; it's Moog circuits with a few less knobs and switches, etc. Purely Moog sound! Has excellent oscillators, filters, and modulator. It has two voices, and is polyphonic. There are trigger and pitch control jacks to link in with an analog system, and stereo RCA outputs and inputs. Comes with WELL PRESERVED original owner's manual."
