The Best of Both Worlds

A feat of instrument design, the SunSyn is a fantastically complex-in-all-the-right-places labor of love from German synthmaker JoMoX. Released in 1999, it can be considered in simple terms as an 8-voice polyphonic analog/digital hybrid, or in a more adventurous way as 8 discrete modular mono synths. It combines a morphable 4-pole analog filter with an unprecedented modulation matrix offering 4096 routings per element, all fully analog yet easily configurable and storable for instant recall. Each voice is outfitted with 2 true analog oscillators capable of saw, square, or pulse with PWM, and 2 guided digital oscillators with hundreds of waveforms and custom sample support.

Resurrecting a Sun

Working with such a complicated instrument has its challenges, especially given its age and limited production. Many parts for the SunSyn are extremely rare and almost impossible to source. In our case, to complete the servicing and refurbishment our tech had to purge parts from a second unit. An expensive and somewhat painful process but worth it in the end, as our sound designers headed off to work on a fully-restored and perfectly calibrated instrument with factory-spec parts.

Deep Sound Design

Sound design possibilities on the SunSyn are nearly endless, and the results of our process with it are evident. From massive, rich, and evolving polysynth sounds created in multi-mode, to devastating and aggressive monosynth sounds utilizing modulations of both analog oscillators, the digital RCOs, and filter morphing. We designed and recorded hundreds of multisampled soundsets, ending with a curated selection of 420 layers, delivering what we think represent the most unique, charactered, and sometimes epic, sounds possible on this machine.

Professional Presets

Bass, Bells, Brass, FX, Keys, Leads, Native Sequences, Organ, Pads, Percussive, Plucks, Polysynth, Strings, Sweeps, Voices, Waveform Analog, Waveform Digital, over 450 all-new + custom designed presets are available, built from a library of 30,660 authentic hardware samples. All presets are fully-editable, meaning you can deeply customize them or even create your own. And the dual-layer architecture of PX SunBox allows you to easily create incredible layered tones from any combination of the included sounds.

Fully-Editable Architecture

PX SunBox gives you a deep and capable toolset for creating and editing patches. From the dual-layer architecture with ADSR amp envelopes, multimode filters with envelope, poly or mono modes with glide, pitch shifting and advanced stereo modes, and handy modwheel mappings, to LFO and step modulators, two feature-rich arpeggiators, and a generous selection of high-quality effects including 3-band EQ with sweepable crossover, drive, Thorus, ensemble, Phasor, digital delay, and Sparkverb.
