SunSyn - Discontinued

SunSyn OS 2.0 Update - we are sorry but from 2017 on no updates can be made.



The SunSyn has to be sent to Jomox in order to perform the V 2.0 Update.
The update includes all modifications, the firmware, recalibration and testing.
We have added an article in our webshop in order to preorder and pay a SunSyn OS 2.0 Update.


What's new?

BIOS
  1. The Sunsyn 2.0 contains a firmware based boot-BIOS, which is executing under any circumstances. Most problems with SunSyns in the past came up by wrong OS midi sysex dumpings which, in some cases, led to non-booting and dead devices. This is not possible any more.
  2. The card slot has no function any more.

RCOs

  1. Own waves or short samples can be transferred to the SunSyn by sysex midi dump.
  2. We provide an editor (PC/MAC) that can convert any WAV or AIFF files on the computer and transfer them to the SunSyn. Each RCO bank can be transferred separately.
  3. The RCO loops now always restart syncronous to a note trigger.
  4. You can define a start point and a loop length, to which the RCO jumps back after reaching the end of the bank. Thus you are able to play back short samples of about 1.5 sec length if both old binary loop parameters (Course and Fine Loop) are set to 16.
  5. RCO 1 can FM modulate RCO 2 now. However, the processing power of the old DSP is limited so that only one way is possible at an acceptable aliasing and tuning range.
  6. As the old RCO algorithm, the aliasing can't be interpolated for the processing power is just too small. Also the VCO sync feature or RCO modulation by VCOs has been cancelled after endless testings because noise and performance were not acceptable.
  7. The background noise of the RCOs is much improved by a hardware modification in order to let samples being played back much more clean.
    More importantly, that improves the whole noise situation of the SunSyn in general.

VCOs

  1. The tuning algorithm has been reworked, The VCOs are tuned much cleaner now.
  2. The envelopes have got an automatic tuning algorithm, too. The tricky manual envelope tuning is history now.
  3. The Pitch Bend Range now is adjustable in semitones across +/- one octave. Also the over- and underrange pitch playing when the VCOs are crossing the borders of the 6 octave keyboard CV range is well performed now.
  4. Glide has been completely reworked. Now it works logarithmic as known from old analog synthesizers and has a much more musical knob range.
Multimode

  1. The voice card allocation in multimode is cyclic now in order to let releasing voices decay properly even though another voice is triggered.
  2. Latency of notes has been much improved and the pipelining has been completely new structured so that hanging and missing notes should be history now.
  3. The multimode bugs like wrong output switching, wrong release, routing assignment interdependence, attack and RCO switching have been fixed. However, still there are some limitations for multimode as there are some parameters global and may affect other voices during context switching. These are: Glide, RCO Bank, RCO FM, RCO Start Point and Loop Length. If one of these parameters are different on two multis, changing of sound may occur between sounding voices.
  4. The clicks occuring on output switching have been minimized. However, it will not be possible to make it better as it IS now.
FILTER
  1. The morphing includes now pole switching. That means, there is a continouus morphing between low and hi pass.


With warm regards,

The Jomox team




We did not reinvent the wheel, but actually the complexity of this 8-voice true analog multitimbral synthesizer hasn't been there yet. The term "8-fold storable modular system" would describe this unit in a much better fashion, and exactly this is the SunSyn. Each voice is an ownstanding monophonic complex synthesizer. The very special idea of the SunSyn is the unique mixture between

analog VCOs and digital waveforms

analog x-pole filters with morphing

analog envelopes with digital LFOs and an

analog routing matrix, which takes alone 50% of the hardware space on each voice card.

Means, the best of all worlds.

Analog is most powerful if it is STOREABLE and you can control it by midi with a computer. Otherwise you start again from the beginning each time...
The SunSyn is a completely true analog, multitimbral and programmable synthesizer. In general, it is equipped with 8 independent voices.

* Oscillator Section

Every SunSyn voice has two true analog oscillators, built up in discrete circuit technology and featuring the classic waveforms saw, square and pulse with pulsewide-modulation.
Besides that, every voice has two so called RCOs (Ramp Controlled Oscillator). It's the first time digital waveforms can be mixed with true analog VCOs. They can interact with the analog VCO driven by software. Therefore digital waveforms become alive like never before and open up new dimensions of sound estethics. All in all you have 4 oscillators per voice, i.e. 32 at all...
Inside the machine you have 7 wavesets with 248 waveforms each stored in the internal flash to feed the RCOs.

* Filter Section

The filter section contains a fully configurable 4 pole true analog filter. On each pole, high/lowpass characteristics and coefficients (i.e. the basic cutoff frequency for each pole) can be adjusted individually. So you have the possibility to crossfade continously from a typical Moog 4pole to an 18db - 303 lowpass to an Oberheim-like 2pole filter.
Additionally, using the HP/LP switching for each pole, it is possible to create the most spacy bandpass- and highpass-filter sounds.
Furthermore, you can store all filter-parameters in 2 scenes and MORPH (in the analog domain!) between them.

* Envelopes

According to the machines conception, both envelopes are discreet analog circuits and super fast. One can be inverted. Typical envelope modulation paths are hardwired and have their own knob on the front panel.

* LFO's

There are two LFOs per voice. Each one can be delayd or applied to events. Waveforms are triangle, saw up/down, square and random. The rate is adjustible between approx. 1kHz and 0,02Hz to create super slow sweeps.

* Modulation

One of the most exiting innovations of the SunSyn is the routing system. It turns the SunSyn into an 8-voice modular synth with programmable routing system. And it is absolutely easy to use.
In addition to the fixed routings (e.g. Env1->VCA) you have 4 flexible and programmable routing paths per voice, called Routing Element.

You can picture routing elements as a modular system's cable, with two inputs (sources) and one output (destination). They are connected by an electronically controlled knob (modifier) to control the intensity.
The intensity itself can be modulated by any Midi-Controller (e.g. controller, velocity, aftertouch) or by an analog audio-signal from the SunSyn. So you create 'modulated modulations'.
Besides that, the signals of each voice can modulate among each other. Up to now, this was only possible with 'real' (and huge) modular systems.
Everything works of course in the analog domain. Therefore no operation is limited by fixed point calculation errors (as in DSPs), but instead offers full dynamic-range for chaotic effects which apear on many modulations.
Every modulation path is easy edited and understandable by one single view on the front panel.

An example:

Both VCOs are cross-modulated. This needs 2 Routing Elements, one for each voice. The intensity of the modulation can be controlled by e.g. key velocity. But this is just for starters.
At the same time, an external audio signal is mixed with noise and cutted into pieces by LFO1 and is mixed into the filter input.
Now there still remains one Routing Element to e.g. ringmodulate RCO1and RCO2, and let the result modulate the VCA amount (if RCO2 is the source and RCO1 the modifier, both signals get multiplied; the result is a ring modulation).
The final sound result should be spaced out in every sense of the word.

* Control Panel

There is a knob or lighted button on the control panel for every important function. All in all, there are 40 of them.
The SunSyn has a 48 character-LCD with 4 soft-controllers and 4 soft-buttons to handle several edit-menues in an easy way.
A three character LED shows programm number and the actual parameter value.

* Sound storage

The SunSyns internal memory can handle 256 single sounds, 128 multis and 7 wavesets.

* Midi

All knob movements and keypad events are sent and received as Midi controller data.
We will deliver editor templates for the best known software sequencer systems.

* In / Outputs

The SunSyn has a stereo-out. Stereo-panning can be modulated by an own LFO. There are also 8 freely routable individual outs. All out sockets are electronically balanced tip/ring on 1/4 inch jacks. The headphone-out has its own volume knob.
Besides that there is a stereo input to send external audio signals or control voltages into the SunSyns routing system.

* Power supply

The SunSyn has an internal power supply. It is a clean and computer controlled audio power supply, specially designed to avoid any unwanted effects to the audio circuits. The line voltage is switchable 230/110V and the power cable is removable.

* Casing

The SunSyn is housed in a solid metal case with wooden side panels. It can be used as desktop unit or can be installed in a 19" rack by swapping the metal side cheeks underneath the wooden panels.
