Roland Juno-106 (Part 3 - Back From The Spa)

After not very long at all, the voice board for my Juno-106 came back from the Synth Spa. Frankly, I was a little jealous. While I was working away in busy, noisy Tokyo, my voice chips got to spend a nice vacation relaxing at the spa in Tennessee. It obviously did the trick because they sound great now.

I opened the box to find the six chips stripped of that horrible black resin coating. They’ve been installed in sockets now so they can be easily removed. They’ve even been autographed by Allen, thus identifying his handiwork. Remember, Allen honors his work for eight years so it makes sense that he’d want to be able to identify them.

After screwing the board in and re-attaching the wire to the test point (remember, I have a “rare” rev 1 board) I fired it up. And let me tell you, I wouldn’t have been surprised if angels had flown out of the thing, it sounded so good. Here was that famous Juno sound in all its glory: thick pads (there’s really only one oscillator here?), bouncy bass, luscious sweeps.

Feeling nostalgic, I decided to load in the original factory patches. It’s easy enough to do from your phone, and I was soon luxuriating in 1980s synth pop heaven. Remember, not only does Allen refurbish the chips, he also calibrates it. I could really hear it in the patches that make use of the self-oscillating filter to add extra harmonics.

I had been hoping that getting the board back would encourage me to keep going on the restoration, and it really has. The work that needs to be done—particularly refurbishing the sliders—doesn’t seem so intimidating now that I have it singing. I’m actually looking forward to pulling them out and taking them apart. That’s how gorgeous this thing sounds.

Unfortunately, the low C is still dead, and if I don’t toughen up the solder joints for the heat sink transistors soon my celebrations may be cut sadly short. The workbench awaits.

Korg Poly-800 (Moog Slayer Filter And Battery Mod)

I’m trying to improve my electronics skills. I thought modding might be the logical next step from changing internal batteries and swapping out tactile switches. I’d like to add MIDI to my Korg Poly-61 and maybe improve the MIDI on my Roland JX-3P. These mods require skills above and beyond what I have now, and I certainly don’t want to wreck them in the process, so when a cheap Poly-800 became available on Yahoo Auctions, I snapped it up in the hopes of trying the Moog Slayer Filter Mod. As anyone who’s looked at a Poly-800 knows, there are no knobs on the front panel, just a few buttons and a lot of teal. I couldn’t do much about the teal but I could add two knobs to bring direct control of the filter and cutoff parameters to the fore. Seeing as it’s a Poly-800, and they sell for around $100 in Japan, I wouldn’t be too disappointed if I killed it. I could always sell it for parts and get my money back anyway. Cosmetically, my new Poly-800 wasn’t in terrible shape. There was so

The Mysterious Case Of The Pink Japanese Casio SK-1

It’s often said that the Casio SK-1 was the first mass-market affordable sampler. Not long after the introduction of such behemoths as the Fairlight and Synclavier, whose price tags were more in line with high-end cars than musical instruments, Casio managed to get sampling into the hands of the unwashed masses. Including the unwashed hands of a certain junior high school boy, who saw it as a way to finally realize his dream of making a perfect copy of Dead Or Alive’s “You Spin Me Round (Like A Record).” I had the synthesizer, a Korg Poly-800 recently received for Christmas. I had the studio, in the form of a keyboard amp, Numark mixer, and belt-drive turntable. All I needed was the drums. It was this, more than the sampling function, that really had me excited about the SK-1. I could just hear it: the rapid-fire hand claps, the machine gun cowbell. All of that Hi-NRG rhythm would soon be mine. Of course, anyone who’s heard the SK-1 (or any other Casio home keyboard for that mat

Roland HS-80 SynthPlus 80 (Alpha Juno 2)

Although I listened to industrial music all through high school, and loved groups like Front 242 and Skinny Puppy, my interest in electronic music really exploded when I discovered techno and rave in 1991. I loved the energy of it but mostly I loved the sounds. It was unabashedly synthy, and each song was seemingly built around one or two incredible sounds that just repeated. It was glorious. I loved all the hoovers, but especially the Dominator, so if you had put money down with a bookie in 1991 that I’d someday be the proud owner of an Alpha Juno synth then you’d be a winner today. Well, almost. Instead of buying a reasonably sized Alpha Juno or Alpha Juno 2, I had to go and get the HS-80 SynthPlus 80, the rather unwieldy and, it has to be said, ugly home version. Introduced in 1987, a year later than the original Alphas, this behemoth widened the case to include an amp and two speakers. Gone are the fetching membrane buttons, replaced with D-50-style black push-button jobbi
