"Vintage 1977 Roland MC-8 Microcomposer 8-Channel Analog Sequencer, complete with the crucial proprietary data cable, as well as the original manual with demo programs, a pad of program data sheets, four CV/Gate cables that came shipped with the unit when new, and the original factory box. This is the cleanest and most complete example of this rare sequencer that I'm personally aware of. Cosmetically it's almost like new, with only a couple small nicks/blemishes. It's currently working 100% and is fully loaded with 15,936 bytes of RAM.

I tested it just prior to this listing in Oct 2022 by loading in the "Odd Rhythms" program data and recording all the parts one by one into my computer, using the MC-8's onboard sync capabilities, and everything worked fine. The demo video here is a different version of "Odd Rhythms" that I recorded with this unit many years ago.

The only quirk of this unit, that I believe to be something in the particular firmware revision that's installed, is that when running in loop mode, there's a slight hiccup at the loop point. Also, there's a similar hiccup at the very beginning of a sequence when the unit is slaved to the sync tone. Some years back I had another MC-8 that didn't exhibit these particular issues.

The only servicing I've ever had done on this unit was several years back when the clock chip needed to be replaced."

  1. wow - the asking price for 70s Roland gear has gone through the roof. Only a few years back $2000 was top dollar for one of these.
