Sequential Circuits Model 700 Programmer

via this auction
"Mark 2 In 1979 the Mark 2 model was released with front panel V/octave trimmers for the 3 control voltages, and a single multi-way socket for a single cable connection to the partner synthesizer. The Mark 2 has revised PCB's and a slightly different circuit design. The original CA3080 and matched transistor design was updated to use SSM2050 and SSM2020 chips, along with TL072 Op Amp's. The high quality sealed cermet pots were also replaced with standard carbon pots. All these changes meant the Model 700 could be manufactured for less money.

Sequential Circuits went on to sell over 200 Programmers, and it was still in the catalog in March 1981.

The Model 700 has a place in synthesizer history and it provided some funding and technical R&D for the legendary Prophet 5. Below is a Mark 2 version with Prophet 5 knobs, and lettering above the tactile switches. The 7 segment display is larger and the patch Record facility has a red button rather than being on the right hand lower toggle switch." via Nick.

  1. I had the Mk 1 version of this, which I used with my Serge system in the late 1970s. It was pretty darn cool for its day. It could be used as a step sequencer, too.

  2. I used it live with the Minimoog on Moog Cookbook tours. It was amazing to be able to play a fat bass tone one second and jump to a short attack, filter sweep sound several octaves higher the next moment. No routing was programmable, but with a modular or ARP 2600, you could also control three notes at once.
