JoMoX SunSyn

Jomox SunSyn Image

Jomox introduces their first major analog real-time synthesizer. It's a true analog with 8 voices (4- and 6-voice versions available) housed in a classic looking desktop-style case with wood end-cheeks, 40 knobs, 42 buttons and 85 LED's! It's also rack-mountable if you prefer.

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.

The new SunSyn is a true analog synth built for the wealthy synthesists of today. For total analog control and sounds, check out the SunSyn, especially if you can afford it!

stunning sounds period but x-pensive too bad these synths stay out of normal peoples price range I can't say enough about the quality so I will leave everyone wondering what they don't have

Respectfully contrary to the view below, I'd have to say the Sunsyn is the most impressive polysynth I've ever had, soundwise. Next to the A6 and OB-Xa the Sunsyn has a richer pallette and more powerful sound. Better UI than the A6; much faster. Fantastic bass-end and the filter is light-years from a VST - in fact of ALL filters in any synth the Sunsyn has, without a doubt, one of the very best. Yes there are some bugs but I'm still running pre-2.0 OS and will be sending it to Jurgen for the mods/upgrade soon.
As for cost, these hold their value and will only increase due to only a couple hundred being made. I paid over 4K for it and have no anxiety about the price ever falling.

Sunsyn OS 2.0 upgrade is available only directly from factory (well one man operation is probably not real factory, but still). Guy behind Jomox is great and inventive.
Sunsyn is teh best thing done so far by Jomox and most likelly the most inovative analogue polysynth of modern age. It is definitelly step up from simple classic synths, it offers many new capabilities, excellent MIDI, rather simple and ergonomic approach.
It sounds fresh and it can't be directly compared with anything on the market.
Latest OS offers all necessary improvements on bugs previously reported and now machine is complete, reliable and totaly worth to have.
Compared to Studio Electronic Omega/Code or Andromeda, I would give slight edge to Sunsyn.
In simple words, Susnyn is the top choice of modern analogue synths, most likelly the best one.
There are rumours that Jomox will produce new batch of Sunsyn 2.0, but who knows.

I may be missing something with this synth, I've owned it for a little over a year now and it just doesn't compare to many of my vintage synth's which cost a fraction of the price. I refuse to sell it as they've lost a lot of value since I purchased mine for $3000.00 USD. The system hangs up sometimes and I am forced to reset, the tones of the filter are my least favorite aspect of this synth, it doesn't sound to far from a VST plugin which I was personally upset about considering how much I love the JoMox T-Res stand alone filter. Modulation options are a plus but they dont make up for the poor almost 'stepping' quality of the filters, one great feature is the unique sounds of the oscillators. Not a bad poly, great concepts and idea's but poor delivery.

The Sunsyn sports two RCOs per voice, not four. At the time of this post {August 2008}, it does not support user-loaded RCO wavesets and there is no sync between the VCOs and RCOs. JoMoX have announced that version 2 of the Sunsyn is in development, and that this will finally introduce user wavesets. VCO and RCO sync seems unlikely {}.

It is, nonetheless, a stonkingly great polysynth.
