Synthchaser #094 – Roland MC-8 MicroComposer Vintage Sequencer Repair

I couldn’t pass up the opportunity to repair this rare and interesting early sequencer made by Roland. Very few of them were made and even fewer still exist today. But there’s no service manual or schematics!

So we have a look around inside and see what makes it tick, and I show you an approach I use for tracking down problems I don’t know I’m looking for. And after it’s fixed we take a peek at it in action. It’s hugely different from other sequencers of its time.
