Roland MC-8 Micro-Composer

Vintage Roland MC-8 Sequencer Archive


This blog will be an information resource for the 1977 Roland MC-8 Micro-Composer, the grand-daddy of all modern digital sequencers. I won’t be able to offer any comprehensive tech support here, but hopefully over time there will be enough info accumulated to get you going. Please stay tuned while I gradually add stuff!

In the meantime, a good intro to the MC-8 may be found in the article that Chris Carter wrote for Sound On Sound Magazine in the late 90s.



  1. Thanks so much for posting a PDF of the Owner’s Manual! I bought my MC-8 years ago on eBay, but it didn’t have either the buss cable nor the manual. After identifying and obtaining a pair of male Hirose 60-pin plugs, I was finally able to make my own cable.

    I had to figure out minimal programming using an MC-4 manual, but features like programming via a keyboard controller were lost. Until now. I can finally learn the full capabilities of the MC-8 — and in time maybe post some Youtube videos of my own!

  2. LOVE this blog. I have an MC-4b and it’s amazing how little information there is out there. I love working with the thing!

  3. Hello, my name is matt and I am the owner of MC8 #650608 like many I am missing the serial cable that connects the two components. If you have any info on how to build or find another serial cable I would really appreciate it. Thank you for creating this blog!
