"PERFECT working condition and in near perfect physical condition. There are a few scratches on the removable wood sides. This can be setup and installed on a rack mount or used as a tabletop. The bottons, lights, LED readout, silkscreen are all in perfect condition.

Jomox's first major analog real-time synthesizer. It's a true analog with 8 voices, 40 knobs, 42 buttons and 85 LED's!

The SunSyn features 2 analog oscillators (VCO's) per voice. The waveforms include sawtooth, square and pulse with pulsewidth-modulation. But in addition to these are the new Ramp Controlled Oscillators (RCO's). The RCOs follow the VCO characteristics like modulation, sync, tuning and frequency alterations. The RCO's use digital sounds which come from 4 wavesets, each with 256 waveforms each. In effect, these digital sounds get an analog treatment for nicer, warmer and fatter tones. There are 4 RCO's per voice and wavesets can be added via PCMCIA-card.

The filter section is also a true analog design but with very modern features. It is a 4-pole filter but fully configurable with independent high pass and low pass features available. Create filters that range from the sounds of a Minimoog, to the squelchy 303. Filter settings can be stored in one of two scene memories and real-time Morphing between scenes can be accomplished.

As for modulation, JoMoX has devised a clever Routing System for the SunSyn, turning it into an 8-voice modular! It is used to virtually patch between various modules or parameters. There are up to 4 Routing Elements per voice with 4,096 possible combinations per Routing Element. Modulation paths are configured using the front panel display screens. This modular approach to signal routing is a feature usually found only on the huge, expensive classic Modular synths by ARP, E-mu, Moog and Buchla. Unlike those, however, the SunSyn features complete patch memory (350 patches and 150 multi-patches) and multitimbral MIDI implementation. Most parameters can be controlled by MIDI, and controller/editor templates for most sequencers will be, or already are available. As for output, there are stereo outs, 8 freely routable individual outs and a stereo input to run external audio through the Routing system.

Buchla 252e Polyrythmic Delays

video upload by Kent

"This is a tough one to write up and summarize. It certainly evolved into something rather different than intended.
The primary reason being that the 252e and/or 251e lost their programming twice! Twice for the 252e (the core of the show) and once for the 251e.
I’ve never had the Atmel products lose their minds like this before. I think that they are rather sensitive to low voltage conditions (brown outs) as they power up as this when they lost their minds. The currently loading preset gets scrambled or wiped. As can be see in the short ancillary video below, the 252e became unresponsive.
That’s two trips to the 10-panel case in order to be reflashed with firmware and three runs at programming the damn thing.

I was so exasperated that I nearly pulled everything so that I could start on the other 3 ideas that I wish to explore and execute. I did promise myself that I would endeavor to be less concerned with perfection and be more concerned with simply getting anything of interest out into the world. It doesn’t have to be novel. It doesn’t have to be world-changing. It just needs to get out there if there is even anything 51% interesting in the recording; I do have some standards after all!
I brewed up a double espresso and hit ‘record’.

It started as an E Minor progression with evolution to… Fuck if I know anymore. That stuff got deleted. I eventually threw in some Whole Tone stuff (especially noticeable toward the end) and smashed it all together in gobs of delay via new toys from X1L3: a Shard, an Underwurlde (messed up delay), and a circuit bent and high augmented with Korg MS20-ish circuits (plus a delay) drum machine that used to be a Yamaha DD-7. It is now a rather more interesting and useful X1L3 DDX.

Basically,
the BLUE rings on the 252e went to the upper macro oscillator of the 1979 DAO
The GREEN rings to the lower part of the DAO (ratcheted bell sounds)
Both using their internal VCAs, which I also used to modulate “Color” & “Timbre” at times.
Both voices went into the Analogue Systems RS-290 delay. The Blue voice also went, in parallel, to the Underwurlde which then went to the 290. It’s a cheat for keeping delay nonsense in synch even though the Underwurlde was hand synced to tempo.
RED rings were the 259e into a 292e LPG. Lots going on there and the Pendulum/Ratchet was acting as a burst generator. I was using the 251e for that but didn’t want program that again.

Studio.h

CSR doing its scaling job plus attenuation of audio signals along with manual muting of both audio and gates/triggers. Love it.
254e was being controlled by the Buchla 266e to quasi-randomly filter out some of the drum rolls/fills for the Green ring. It also had a manual Gate voltage connected to it so that I could inject tones into the X1L3 Shard.

Northern Light Modular 2TT
Taking the clock from a channel of the 251e and distributing it, mangling it, and doing its thing. All Eurorack connects to this as well.

X1L3 (pronounced “Exile”) DDX:
It provided percussion in 3/4 via Malekko Varigate 4. I also played it manually at times. It ran into the TipTop Áudio Z-DSP with the Valhalla “Shimmer” card but set to program #8 for pitched echo.

https://x1l3.bigcartel.com

Lots of Eurorack. Some mentioned specifically at the end of the video. I left out a lot as I wanted to get this video posted. Best Supporting Cast:
2x Folktek Matters. All Even Beat Count percussion.
Tyme Sefaris Mk1 & Mk2… Connected to Matters
Audio Damage (I know, right?!) Grainshifter on one of the Matters.
Lots of Eurorack sequencing.
As I look back on what was used, much of the processing was changed due to reprogramming things. All compression pulled and I just mixed it ‘live’ without multi-tracking.

Time to tear this patch down!"

"This synthesizer uses the same multi-oscillator synthesis system (MOSS) tone generator found in the Korg Prophecy which is the reason it is touted as a polyphonic Prophecy. It implements 13 synthesis types, all derived from the original OASYS synthesizer."

Note the original OASYS was never released as a stand alone synth. The Z1, released in 1997, used the technology from it. The OASYS PCI card for the PC (see wikipedia on it here), was released in 1999.

I actually own a Z1 and a Prophecy, and always thought the sound of the Z1 was a bit "dampened" for lack of a better word. It was as if you couldn't quite get the filter to open up all the way - it lacked that extra level of clarity and oomph. I once spoke to someone involved with the development of the Z1, and was told that the DSP chips were underpowered for the engine, and they ran out of time needed to optimize the software to compensate for that. My memory is a little fuzzy though; this was a long time ago. Regarding the Z1 being a poly Prophecy, that is correct only to an extent. They use the same source engine, but the parameters on the two actually differ. One of my favorite patches on the Prophecy is "Prophetic Step". I was curious how it would sound polyphonic, so one day I decided to try an mirror the parameters on the Z1. I discovered that the were not the same, and never managed to program the patch on the Z1. I hate to say it but the Prophecy in general, also slightly sounded better to my ears. The Z1 is still a great synth and offers parameters and physical models not available on other synths, aside from the mono Prophecy of course.

The OASYS synth we all know now followed much later in 2005. Wikipedia has an article on it here. As always use the info on Wikipedia as general information and not fact. They still have the Buchla dates wrong. You can find the corrected dates here.
