ASM Leviasynth® Introduced: 16-Voice, 8-Oscillator Digital-Analog Hybrid Synthesizer

Leviasynth® is ASM’s all-new 16-voice, 8-oscillator digital-analog hybrid synthesizer, created to expand on the foundations that made the Hydrasynth® a staple on stages and in studios worldwide. Housed in a rugged solid-steel chassis and equipped with an enhanced Polytouch® polyphonic aftertouch keybed, Leviasynth® introduces a powerful new hybrid synthesis engine designed for uncompromising sonic exploration.

ASM Leviasynth®

Its four-pole analog filter with a dedicated pre-drive stage brings authority and character to every sound—delivering basses that hit with weight and depth, leads that cut cleanly through a mix, and pads that retain warmth, clarity, and definition. From evolving ambient textures to driving organs, expressive leads, brass, and bass sounds, Leviasynth® invites the player further into its expansive sonic territory.

At its core lies an advanced algorithmic sound engine featuring eight oscillators per voice and seven distinct synthesis types, freely configurable across more than 140 algorithms, including fully user-created designs. 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 blends digital precision with unmistakable analog character. A versatile digital filter section, offering 18 models with morphing and drive, feeds a custom analog pre-drive stage and a Q-compensated four-pole analog low-pass filter, resulting in depth, weight, and a distinctly musical warmth.

Modulation and expression are central to Leviasynth®’s identity. Thirteen envelopes, five LFOs, a comprehensive modulation matrix, per-voice modulation offsets, and extensive Macro controls ensure constant movement and flexibility. Real-time algorithm morphing allows sounds to evolve organically, seamlessly shifting between textures and opening access to deeper, more complex timbral spaces.

For composition and performance, Leviasynth® features a three-track sequencer and an eight-mode arpeggiator with Ratchet, Probability, and Entropy controls. These tools can operate independently or in tandem, supported by hands-on controls, expressive Envelope Bias touch response, illuminated wheels, and a four-octave ribbon controller that places sound shaping directly under the player’s hands.

Available in both keyboard and desktop/rack/VESA formats, Leviasynth® adapts effortlessly to studio and stage environments. The keyboard version offers a 61-key semi-weighted Polytouch® keybed, while the compact model replaces keys with 16 Polytouch®-enabled pads—both complemented by a full-color touchscreen for intuitive editing and immediate visual feedback.

Leviasynth® continues ASM’s tradition of building instruments that exceed expectations.

Designed for players seeking depth, control, and sound that rewards exploration.
