Sound designer Jexus (sounds-for-synths.com) shared this demo of the patches that he created for the Leviasynth. Jexus is know of exploring the nooks and crannies of sound design with his patch library, and the Jexus Leviasynth presets cover a huge range.
Here’s what Jexus has to say about the Leviasynth presets:
“In 2025 Ashun Sound Machines contacted me and asked if I would like to create a set of unique patches for their upcoming synth. No details were disclosed about the instrument but, as you can imagine, I was curious. I agreed and several weeks later a monster 8-oscillator synth arrived at my doorstep.
Today all of you can see it and hear it in action – the LEVIASYNTH is ready!
Here’s a quick video with some factory presets I created on the new Leviasynth. In this demo I kept the internal reverb low and did a fair amount of tweaking to give you a better idea of the timbre / behavior of the synth.”

Host Ziv Eliraz – in his latest loopop video – takes an in-depth look at the new ASM Leviasynth, a 16-voice hybrid digital/analog synthesizer from the creators of the Hydrasynth.
“Its interface and effects resemble Hydrasynth in many ways, but the oscillator structure and workflow is totally different and new,” he notes. “It’s got 8 oscillators, 13 envelopes and an analog filter per voice, a new sequencer, and plenty of other updates throughout.”
As ever, Eliraz offers an overview, plenty of audio demos and his thoughts on the pros and cons.

Ahead of the 2026 NAMM Show, being held Jan 22–24 in Anaheim, California, Ashun Sound Machines (ASM) has introduced the Leviasynth, a new 16-voice, 8-oscillator digital / analog hybrid synthesizer.
The Leviasynth combines many of the features that have made its Hydrasynth a hit – including rugged build, the Polytouch polyphonic aftertouch keybed and ribbon controller – with a new hybrid synth engine that combines the best of analog and digital worlds.
The Leviasynth takes the Hydrasynth aesthetic and attitude and looks like it’s expanding on everything that was beloved about that latter-day legend.
Available in both keyboard and rackable desktop versions, the Leviasynth’s 8 oscillators can be manually organised into customized groups. Reffered to, as ‘algorithms’, this approach can significantly affect the sonic results in terms of how the oscillators affect each other. It’s classic FM synthesis in principle, then, but ultra-modern in attitude.
Couple that with the new idea of ‘algorithmic morph’ (an idea that has seemingly taken its cues from Audio Cookbook’s creative Hydramorph software) and a ‘nearly unlimited’ number of configurations for these individual oscillators are opened-up. 144 preset algorithms are ready to go, all of which offer one additional algorithm that can also be customized per-patch.
All of this programming can be done natively, using an easy-to-navigate user interface, viewable via a snazzy multi-colour touch screen.
The keyboard version comes with a 61-note Polytouch polyphonic aftertouch keybed, with a lengthy 4-octave ribbon controller prompting users to sink into full intuitive control of the Leviasynth’s reactive aural results.
The Leviasynth is also MPE-compatible, and indications are that it has embraced the format in a much more well-rounded way than its rather limited predecessor. The portable desktop version, in contrast, features 16 Polytouch pads.
Back to the tech, and over 300 waveforms can be assigned to each oscillator, each of which have 7 independent oscillator modes to maximise the diversity of the timbral output. There’s also 5 LFOs and 5 envelopes, as well as the effects package previously found within Hydrasynth.
Leviasynth also offers a three-track sequencer and an eight-mode arpeggiator with Ratchet, Probability, and Entropy controls, designed to work independently or together. Other performance features include deep hands-on controls, expressive Envelope Bias touch response, illuminated wheels, and a four-octave ribbon controller.
You can switch between Single or Multi modes to allow all 16 voices to be active per-patch, or to split the voices into two parts of 8 voices each, respectively. The additional ASM Patch Manager software for Mac and PC is on hand for more intricate control.
The Leviasynth’s front control panel builds on Hydrasynth’s design philosophy and presents an easily-linked and self-explanatory overview of the routing in play.
Here’s what they have to say about the Leviasynth:
“With its 4-pole analog filter with pre-drive, create everything from thundering bass to shimmering pads.
At the heart of Leviasynth is an advanced algorithmic sound engine featuring eight oscillators per voice and seven distinct synthesis types, freely configurable across more than 140 algorithms, including user “custom” algorithms. Two independent layers can be stacked or split, while voices may be paired into true binaural stereo sets with independent modulation of carriers and modulators for wide, animated soundscapes.
The signal path fuses digital precision with analog character. A flexible digital filter section, offering 18 models with morphing and drive, feeds a custom analog pre-drive stage into a Q-compensated four-pole analog low-pass filter, delivering depth, weight, and searing warmth.
Modulation and expression form the lifeblood of Leviasynth. Thirteen envelopes, five LFOs, a deep modulation matrix, per-voice modulation offsets, and expansive Macro control keep the sound in continuous motion. Through real-time algorithm morphing, Leviasynth transforms its voices organically, drifting between textures and opening doors to distant sonic depths.”
