Roland MKS-80 Super Jupiter Repair

I recently purchased a Roland MKS-80 in need of repair. Several things were wrong with it including the tuning knob, dynamics slider and “insert cartridge” errors when trying to change the patches from the front panel.

After several days and more than thirty hours of research, parts swapping, and troubleshooting I managed to get it working properly. Read on for an illustrated story of the repair process and audio from the fixed unit.

Example of Posc from Live Performance

I extracted this recording of the Posc from a performance of Words to Dead Lips at Intermedia Arts last November. I left the processing on it that I had used during the performance. At some point I’m going to acoustically record one of the “noise shields” that built for the dancers to use in the piece as a comparison. The “noise shields” have a distinctive sound tailored by the amplification, speaker, and the body of the instrument that is quite different for the direct sound below.

Juno-106 Bad Voice Chip Glitch

As I mentioned in my last article, I was quite disappointed that my Juno-106 arrived with a bad 80017a voice chip, not to mention a laundry list of other technical and cosmetic problems. However, in some ways I enjoyed the challenge of getting it back in working order. All the research, soldering, and fussing with the electronics was kind of rewarding in the long run.

Another thing I wanted to explore were the glitches I could get out of it while the voice chip was bad. So, I recorded 20 minutes of crackly, warbled, weirdness while adjusting sliders and pressing buttons. I’ll be sharing more bits and pieces of this in upcoming articles. For now, here’s an excerpt of glitches from the first few seconds of my experimentation.
