"$450 - Akai AX80 8 voice vintage analog synth in great working shape. This synth was babied after purchase in my non smoking studio and never played out. Fully functional with the following cosmetic issues:

Minor scuffs due to age and in the condition I purchased it in. There's one small cosmetic ding above the Hold button and LED as you can see - the button and LED work fine. Aside from this the membrane is pristine. Looks brand new. No depressions or cracks.

One key was cracked so I glued a small ram chip on it years ago as you can see. It is smooth, not rough to the touch, and feels fine. See Pics.

VCA 30 Velocity LED bar is out. This is purely cosmetic. The parameter works fine and you can see the values change on the red numerical display by the data knob. Only the EQ looking LED is out as you can see in the pics.

If you have any questions, feel free to ask. This is a great sounding vintage 8 voice polyphonic analog synth and it is 100% sonically functional and solid. The AX80 uses the same CEM3372 Filter/Mix/VCA chips as on the Oberheim Matrix-12, Xpander, SCI Prophet-600 and T8. For a full list of what synths use the 3372 see here."

Podcast 275: Jim Coker

Published on May 5, 2019 20Objects

"Back in Podcast 38 [below], we talked to Jim Coker - the developer behind Numerology and the company Five12. Well, it's been five years, and a lot has happened since then. I met up with Jim at Synthplex, and got a quick catch-up; I also realized that we needed to have another interview, because things have gotten very real for him since we last talked!

It's all about hardware, baby. In this case, that would be the Vector Sequencer: a no-holds-barred sequencer for Eurorack systems that brings much of the sequencing power of Numerology into the Eurorack world. This device provides many of my favorite features into its 3u height, so you can expect that I wanted to know how that could happen.

As always, Jim was willing to share - and to be patient as I marveled at what he pulled off. This sequencer is significant enough to occupy the center of a decent studio (much like Numerology itself), and bring the step sequencing game to a new level of awesome.

You can learn more about both Numerology and the Vector Sequencer at five12.com

Enjoy!"

Podcast 038: Jim Coker

Published on Dec 6, 2017 20Objects

"As an electronic music-head, I've been using computers, DAW's, synths and other tech crap for decades now. However, one of my favorite software packages is a program that doesn't try to do everything - in fact, its creator steadfastly refuses to take one certain tasks that he doesn't feel belong in his bit of code.


That creator is Jim Coker, and the software is Numerology (found at five12.com). I started using this at version 1, and it is now up to version 3 (with 4 right around the corner). In this podcast, I take the opportunity to corner Jim, talk to him about his background, his vision of the software/hardware combo, and his view of the future.


This is another case where I've known someone for a long time, but this is the longest conversation we've ever had. What's wrong with me? I need to spend more time with these people!!!


Enjoy!"

Synth Stuff Ep. 55 - Korg Radias

Published on May 5, 2019 tritonrecordings

"The Radias was released a couple years after I discovered my interest in synths and I remember being blown away in the store just by the way this thing looked. It's a bit unusual, but it just looks bad ass. Anyway, lots of people want to compare this to the MS2000 and I would say this definitely has a more processed and modern (by 2006 standards) sound. It reeks of that over-polished, Japanese Korg sound. Every synth collection should have a VA and this one is definitely worth checking out or just having one to make your rack look cool. Also check out the Korg R3 - same sound engine in a smaller package."

Roland MKS-30 Analog Synth with PG200 - Restored Chips

"Roland MKS30 Analog Synth module with the PG200 Controller.

All of the voice chips were overhauled to ensure proper sound and use so no worries there. Comes with the proper cable for the controller and also included are the rack ears with screws to attack to the module (pictured in bubble wrap). Also, the internal battery was replaced. This classic synth is ready for many years of use. Several custom patches are loaded on many banks and there are a few banks with initialized setting so that you can create and store your own.

The sound of the MKS30 is the same as the JX3p and some will say (myself included) that the sound is more versatile and more elegant than that of the Juno106, although its surely in the same sonic family as the juno 106 and juno 60."

✯CLASSIC✯ Teisco S110F Mono/Duophonic Vintage Synth

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Made under licence from ARP- the lo pass VCF is virtually identical in design & sound to the infamous ARP 2600 4012 transistor ladder VCF (the Moog copy!). Twin Osc. both with subsonic capabilities. FM cross modulation (Osc 1 into Osc 2) & ring modulation. White/Pink noise. LFO with vari-shape & Sample & Hold. Two ADSR envelopes. Great filter section with 24db Low pass with resonance (self oscillating-with gorgeous sine wave!), eight octave fixed filter bank finished off with a High pass filter. Duophonic (paraphonic) keyboard with portamento/legato. Touch sensitive (If you happen to be a Gorilla!) modulation pads. CV/Gate in/out & an external input into the filters & VCA.

The two clever bits of the synth's ergonomics are 1.) the five-LED meters to show the amount of modulation of the various sections; and 2.) the little LED arrows showing the amount of actual signal going from sound sources to VCF and VCA. Then of course there is the very unusual onboard fixed filter bank, and the good CV/gate interfacing. This really is one of the most thorough and effective mono/duosynth designs ever.

In good tested working order, some crackle but with use will get better."
