CatSynth Pic: Cat and “Blue-Eyed” Korg Polysix

We recently found this pic featuring a cute cat and a Korg Polysix on matrixsynth.

“Sadly, something has to give. Too much kit in my life!

This is a 1982 Korg Polysix in excellent condition. It’s been fully restored within the past two years, and is in really good cosmetic condition. If you’re looking here, you know the specifications already, so no need for copypasta here.

Work done:

Old NiCad battery replaced with a brand-new NiMH battery. Not a lithium cell. The CPU card was blissfully unharmed by the usual battery leak problems that these get – check the photos.
The power supply transformer has been replaced with a super quiet, efficient toroidal unit, capable of running at 220V as well as 110V.
One VCF chip – an SSM2044 – was replaced with a brand-new old stock item.
Synth was completely recalibrated and tuned and is working perfectly.
A Tauntek MIDI input board was fitted. This really enhances the machine by allowing MIDI note in, as well as syncing the arpeggiator clock over MIDI.

Yes, I changed out the LEDs for blue ones, while replacing some scratchy, worn pots. Series resistors were recalculated to dial back the intensity. It’s not as piercing as in the photos. Will take some more pics soon. I think they really match the panel decals well, by YMMV. I’m happy to change them back to generic red (or anything, really) for the lucky buyer.”

No, it does not appear that the cat is included.

Additionally, there is a sample of a bass line played on this synth.

“A rather familiar bass-line. I’m just testing a newly-repaired Korg Polysix. This is playing in unison mode, although with only five ganged voices. No effects other than a small amount of reverb.”

When I went synth shopping for the first time in the mid 1980s (right after a birthday), among the first I encountered was one of this instrument’s more modest successors, the Korg Poly 800 II. The Polysix was long gone from the catalogs by then, and it was the time when digital synths were eclipsing analog instruments. I was quickly pulled in the direction of the Yamaha synths that dominated that era.

CatSynth Pic: Miep and Roland JX8P

Miep returns to CatSynth, this time with a Roland JX-8P.   You can see some of Miep’s previous appearances via this tag.

The JX-8P was a follow-up to Roland’s popular JX-3P. Some more info on it from Vintage Synth Explorer:

Though it is far more advanced than its predecessor, the JX-3P, the JX-8P has its drawbacks. Hands-on programming is sacrificed and reduced to assigning the parameter you want to tweak to a data-slider near the pitch/mod bender. Enter the PG-800 controller which gives you total control of all the JX-8P’s editable parameters with hands-on traditional slider control. Membrane buttons dominate the front panel of the JX-8P providing access to the various preset and user patches and to page through and assign editable parameters.


Weekend Cat Blogging with Sam Sam: Exploring the Modular and Roland JP-08

Sam Sam checking out the next studio setup

Sometimes Sam Sam ends up in CatSynth pics of her own, as when she recently got up to explore the redesigned studio space.  She is fascinated by the new decorative shelves as well as the narrow band between the video/office corner and the modular synth.

Perhaps she is picking up some scents on the modular case from our recent live performances.

I have been having a lot of fun in the studio lately, especially making videos and exploring our synthesizer collection in greater depth.  I really should be working on some more formal compositions, but it seems I am in more of experimenting and exploratory mood at the moment.  I have also, unfortunately, been battling insomnia.  It ebbs and flows, and on the worst night (about a week ago), I decided to sit up for a while and play with the Roland JP-08 boutique synth.

Sam Sam and the Roland JP-08

The size is actually ideal for playing in bed late at night.  I spent some time exploring the architecture (it’s basically a Jupiter 8 with a few extensions) and came up with some new and unusual patches.  We hope to share them with you in an upcoming CatSynth TV.

The TTSH is an Arp 2600 clone that can be built as a DIY project, as described by The Human Comparator.  San Pedro Labs builds full versions, including wood casings. (They used to be here in San Francisco, but have recently relocated to New Mexico.)


CatSynth Video: Charlotte and Circuit-Bent Big Mouth Billy Bass

Charlotte the cat contemplates the horror that is a circuit-bent Big Mouth Billy Bass.  From Ok Housecat on YouTube.

I was often sardonically amused by this fishy contraption since the commercials in the 1990s.  But now I am genuinely intrigued by its circuit-bending possibilities.  At the very least, it could make for a fun CatSynth TV episode.  I found at least one set of instructions here, but it might be even more fun to just take it aport and just explore with alligator cables.

The Horror…The Horror…
