ASM Leviasynth Desktop Synth

The ASM Leviasynth Desktop is a powerful hybrid algorithmic synthesiser that puts immense sound design potential at your fingertips. With 16 voices, 8 oscillators per voice, dual analogue and digital filters, and a deep modulation engine, it is built for producers who want to sculpt truly original sounds. A responsive multi-colour touch screen, Polytouch pads with polyphonic aftertouch, and MPE compatibility make it just as inspiring to play as it is to programme.

At its core, Leviasynth combines advanced digital oscillators and Hydrasynth-style filtering with an analogue low-pass filter and a comprehensive effects section. Over 300 waveforms per oscillator, 7 oscillator modes, 144 preset algorithms and algorithm morphing give you an almost limitless palette of tones, from glassy evolving pads and brutal basses to intricate, animated textures. Whether you are performing live or building complex studio patches, the workflow is fast, visual and rewarding.

Leviasynth is also a performance powerhouse. The 16 Polytouch pads respond to velocity and polyphonic aftertouch, while the arpeggiator and 3-track sequencer capture both notes and macro movements for evolving, hands-on performances. Single and Multi modes let you use all 16 voices on one patch, or split them into two 8-voice parts for layers and splits, making it equally at home as a centrepiece desktop synth or integrated into a larger rig.

With generous patch storage, deep modulation routing and extensive connectivity including MIDI, USB, CV and gate, Leviasynth slots effortlessly into modern hardware and software setups. The free ASM Patch Manager for Mac and PC keeps firmware and patch management simple, so you can focus on creating and performing.

Hybrid Algorithmic Sound Engine

Leviasynth’s algorithmic engine lets you arrange its 8 oscillators per voice into powerful configurations called algorithms. With 144 preset algorithms and a user-customisable slot per patch, plus algorithm morphing, you can continuously reshape how oscillators interact for evolving, expressive sounds that go far beyond traditional subtractive synthesis.

Deep Modulation and Filters

A flexible modulation architecture with 5 envelopes and 5 LFOs per voice, all freely routable via a 32-slot modulation matrix, gives you precise control over every aspect of your sound. The combination of a Hydrasynth-style digital multimode filter and a 4-pole analogue low-pass filter, complete with pre-drive saturation and self-oscillation, delivers everything from silky sweeps to aggressive, characterful tones.

Performance-Focused Interface

The multi-colour touch screen and intuitive front panel make complex patch design feel immediate and musical. Sixteen Polytouch pads provide a highly expressive playing surface with velocity and polyphonic aftertouch, while MPE compatibility means Leviasynth responds beautifully to modern expressive controllers for nuanced, dynamic performances.

Sequencing, Arpeggiation and Effects

A 3-track sequencer records both notes and macro automation, letting you build evolving patterns and motion inside each patch. The arpeggiator offers multiple modes plus an Entropy function for advanced real-time note manipulation. With two insert effects, two master effects and a wide selection of high-quality delays, reverbs and modulation effects, you can fully polish and animate your sounds without leaving the synth.

• 16-Voice Hybrid Algorithmic Engine - With 16 voices and 8 oscillators per voice, Leviasynth delivers huge, complex sounds ideal for modern electronic production. The hybrid analogue/digital architecture combines clarity and flexibility with rich, musical character.
• Advanced Oscillator Algorithms and Morphing - 144 preset algorithms plus a user slot per patch define how oscillators interact, while algorithm morphing lets you smoothly transition between configurations. This opens up evolving textures and unique timbres that are difficult to achieve on conventional synthesisers.
• Expressive Polytouch Pads and MPE - Sixteen Polytouch pads with velocity and polyphonic aftertouch provide a highly expressive performance surface. MPE compatibility means Leviasynth integrates seamlessly with modern expressive controllers, capturing every nuance of your playing.
• Integrated Sequencer, Arpeggiator and Effects - A 3-track sequencer with macro automation, a feature-rich arpeggiator with Entropy, and a comprehensive effects section let you create complete, animated sounds and patterns inside the synth, reducing reliance on external processing.
