Juno-106 Bad Voice Chip Glitch

Posted on January 12, 2011 by John C.S. Keston

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.

Back in November I wrote an article titled What is Your Favorite Poly Synth? discussing mostly vintage polyphonic synthesizers. One of them that kept coming up was the Roland Juno-106. Researching these popular synths, I found that they are fairly easy to come by, and usually reasonably priced. I found a great deal on one and snapped it up only to discover that it had the dreaded voice chip problem. Fortunately the seller agreed to refund part of the purchase price to help pay for the repairs. Six weeks later I have finally got it up and running, but it took some doing. Read on for more, and the the synth sound of the day.

I just finished collaborating on a grant funded project titled Words to Dead Lips at Intermedia Arts last month. I did live electronic music and sound design, as well as build sound objects that the dancers used in the piece. The collaboration began with choreographer Pramila Vasudevan and visual artist Matt Wells with whom I joined to expand the project in December, 2009. Here’s more documentation including project notes, photos and press:

What is Your Favorite Poly Synth?

Posted on November 18, 2010 by John C.S. Keston

For the last few of years I have been craving the sound of polyphonic, analogue synthesizers. Although I’ve got a collection of aging monophonic (and one duophonic) beasts, I haven’t owned an analogue polyphonic slab since I had an Oberhiem Matrix-6. Before that, it was one of my first instruments, the Korg Poly-800. Both of these synths sound great, but I can’t forget the frustration I experienced with their lack of tactile potentiometers. Although I wish I still had it now, the membrane buttons on the Matrix-6 were especially annoying.

Recently I joined a trio name DGK (Jon Davis, Tim Glenn, and John Keston) that I think would benefit from a versatile polyphonic analogue instrument on top of my Rhodes electric piano. I have few rigs in mind (insert vintage Korg, Roland, or Akai), but I’m looking for a good knob to dollar ratio (more knobs and less dollars). What are your favorite poly-synths and why? Ever get rid of something you wish you hadn’t? Or have you been assimilated by the latest software synths?

The Somethin’ Else #5: I, Synthesizer

Posted on October 6, 2010 by John C.S. Keston

The Somethin’ Else #5, curated by Jon Davis, will take place Friday, October 8, 2010 at the Franklin Art Works, 1021 E Franklin Avenue in Minneapolis. The theme this month is synthesizers.

I’ll be playing my restored Sequential Circuits Pro-One as well as my preferred axe, the Rhodes in the group DGK (Davis, Glenn, Keston) featuring Jon Davis on bass and bass clarinet, and Tim Glenn on drums.

The roster of artists playing this event has reached a total of eleven for four hours of synthesized madness. Artists include The Radar Threat, Moonstone Variations, DGK, Slapping Purses, S/M, SMAK 10K, Soaking Rasps, Dreamland Faces, Low-Gain, Spacebar, and John Vance.

Here’s one of my favorite live recordings from the last DKG performance to give you a taste of what’s to come.
