ASM Leviasynth Keyboard – 16-Voice Hybrid Algorithmic Synthesizer with Analog Filter

Some synthesizers sound good. Others redefine what sound design can be. The ASM Leviasynth Keyboard firmly belongs to the latter. This powerful 16-voice hybrid synthesizer combines advanced algorithmic synthesis with a true 4-pole resonant analog filter, delivering exceptional depth, movement, and character. Equipped with a 61-key Polytouch® keybed featuring full polyphonic aftertouch, Leviasynth opens a new dimension of expression for both studio production and live performance.

Key Features

• 16 voices, 8 oscillators per voice
• Over 300 waveforms and 140+ preset algorithms
• Real-time Algorithm Morphing
• 13 DAHDSR envelopes and 5 LFOs with wide timing range
• 32-slot Modulation Matrix (170 sources, 400+ destinations)
• 18 digital filter models + 24 dB/oct analog filter
• 4 effects processors per part + delays and reverbs
• 3-track sequencer with Probability and Drift
• Advanced arpeggiator with Entropy, Ratchet, and Chance
• Full MIDI, USB, and CV/Gate connectivity

Next-Generation Hybrid Synthesis

At its core lies a completely new algorithmic synthesis engine. Each of the 16 voices features 8 oscillators capable of operating in Phase Modulation (PM), Linear FM, Pulse Width Modulation, HTE Sync, and three types of Phase Distortion. This is not a traditional subtractive architecture — it is an open sound design platform built without limitations.

Oscillators can be arranged using over 140 preset algorithms or fully customized in Custom Algorithm mode. With Algorithm Morphing, you can seamlessly blend between eight selected structures in real time, effectively modulating the architecture itself for evolving, dynamic textures.

The digital filter section includes 18 models ranging from classic LP/BP/HP types to vowel and multimode variations. The signal then flows through a genuine 4-pole analog low-pass filter with pre-drive saturation and self-oscillation. The result is organic warmth and depth that purely digital instruments simply cannot replicate.

Unmatched Expressive Control

The Polytouch® keybed with polyphonic aftertouch allows independent modulation per note, giving performers unprecedented expressive control. A 4-octave ribbon controller, illuminated pitch and modulation wheels, and 8 assignable macros per part provide immediate hands-on performance capability. Multiple polyphony modes — including mono, unison, poly-unison, and binaural stereo — expand the sonic palette even further.

Motion, Modulation, and Sonic Evolution

With 13 DAHDSR envelopes (looping, BPM sync, multiple trigger modes), 5 versatile LFOs including Step LFO mode, and a powerful 32-slot modulation matrix, Leviasynth delivers constantly evolving textures. Nearly every parameter — including sequencer and arpeggiator functions — can become a modulation destination.

Sequencer & Arpeggiator Built for Performance

The integrated 3-track sequencer (2 polyphonic note tracks + 1 macro automation track) supports up to 128 steps per track with Probability and Drift options. The arpeggiator features modes such as Up, Down, Random, Chord, and Entropy, enabling real-time rhythmic transformation. Both systems can operate independently or interact for complex generative patterns.
