Roland Juno 106 (#8) – common problems with the Juno chorus

Roland Juno 106
yet another Juno 106

Since I always do pretty much the same work on every Juno and have posted about it 7 times, this time I’m going to go more into depth about two specific, very common problems a Juno 106 chorus/jack board can have. Continue reading “Roland Juno 106 (#8) – common problems with the Juno chorus”

Sold! Now FOR SALE in our Reverb shop!

I bought this Juno from a guy named Mike in South Jersey, with a shaved head and a gold chain. I met up with him at his garage studio behind a roller rink, where the Juno had been used for over 25 years by musicians providing live accompaniment for the roller skaters. Now the music is performed by two “old cowboys” (his words) on two Hammond console organs. I also met Mike’s overweight English bulldog, who he introduced to me as his girlfriend. I think her name was Bethany. Continue reading “Roland Juno 106 (#7) – this is New Jersey”

Korg MonoPoly

This MonoPoly had the worst kind of problem when it arrived: a very intermittent problem. It had a tendency to fade out randomly, and then randomly fade back in. The first day it was here, we ran it for 12 hours continuously without any such incident. It took us a long time to figure out what was going on because it was hard to get it to replicate the problem. Continue reading “Korg MonoPoly”

Oberheim OB-8

This synth is a beast! It’s almost as deep as my work table. When it arrived at the workshop it was really freaking out.  It would overheat after 10-15 minutes and the CPU would crash, freezing the panel LEDs and making no sound. It was missing maybe half of its notes and apparently one of its voices. Continue reading “Oberheim OB-8”

Quasimidi Polymorph – knob jitter hell

The unapologetically boring-looking Quasimidi Polymorph is a very powerful VA polysynth from the early 2000s that allows you to sequence and play back 4 parts on 4 different synth sounds, recording and playing back all the parameter edits you make along the way, and send them out on 4 individual outputs.  So basically it is 4 sequencing polysynths in one.  Continue reading “Quasimidi Polymorph – knob jitter hell”

Roland Juno 106 (#6)

Roland Juno 106

After I finished actually working on this Juno, I finally caved in to my perverse scientific curiosity and decided to see if I could use parts from a few half-failed Juno chips (ones from various Juno 106s I’ve worked on, that weren’t fully restored by the soaking/stripping process) to create some fully-functioning ones.

Roland Jupiter 6 – calibration tips

The Jupiter 6 is one of Roland’s two most beloved 80’s polysynths, the other being the Jupiter 8. While I was looking for service documents for the Jupiter 6 though, I came across some absurdly aggressive forum posts from people who don’t like this synth and are pointlessly mad that a lot of other people like it a lot. Continue reading “Roland Jupiter 6 – calibration tips”

I just finished restoring the electronics on this beautiful Juno I bought directly from Japan, with all its voice cards failing, to restore and sell.  I was going to announce it as “for sale” here on the blog, but I had already posted it on our Reverb shop yesterday, and by the time I checked my email today it was already sold.
