Roland MC-4b, MTR-100, and OP8

Title link takes you to more shots via this auction.

Details:
"This is a Roland MC-4b MicroComposer Digital CV/GATE Sequencer for sequencing analog synths with CV/GATE inputs. It comes complete with the extremely rare optional MTR-100 Digital Cassette Recorder and the somewhat rare optional OP-8 DCB converter for controlling a Juno-60 or Jupiter-8 via DCB interface. It also includes the original manual, 20 Maxell M-90 Data Cassettes (recommended by Roland in the manual), and an original DCB cable for interfacing with a Jupiter-8 or Juno-60. It took me over 12 years to complete this set, now you can save yourself the time and effort by buying them altogether. This sequencer is the tightest sequencer on the planet, and can sequence CV/GATE synths with ease. It was used by many artists to create some of the best music ever heard. Former users include Vince Clarke, Rational Youth, Human League & Martin Rushent (Dare!), Richard D. James (Analord), John Foxx, Wang Chung, Tears For Fears (The Hurting), Toto, Devo, YMO, and many more. A keyboard with CV/GATE output can be hooked up to enter notes via keyboard, or you can enter notes using the calculator keypad. This MC-4 is the more difficult to find expanded model with the "B" designation that allows you to save patches to the supplied MTR-100 Data Cassette Recorder at twice the speed as normal, and also contains double the memory capacity. This is my last MC-4b, and it will be sorely missed. You can listen to a song I composed entirely with this setup and an additional MC-4 here: http://isatellite.info/lifeintokyo.html.

Ken Stone's Programmer/Sequencer

Bookmarking this one for "one of these days." Title link takes you to more info. Be sure to check out the rest of Catgirl Synth.

"The Programmer/Sequencer is a Serge inpired multi-stage sequencer. Unlike most sequencers, this one makes no use of binary counters. Rather, it uses a set of individual stages, each one directly accessible. As such it could be considered to allow "random access". The first sequencer produced by Serge was a 4017 based counter that put out gate pulses. In order to get a control voltage sequencer, the gate outputs were fed to the input stages of a multi-state programmer. Usually built in groups of four, but sometimes coupled through a switch, these programmers would only allow a single stage to be active at any time, outputting the corresponding control voltages to their bussed output jacks. The stages could be selected either via a gate/trigger input or a panel mounted push button."
