ASM Leviasynth Keyboard 61-Key Hybrid Synthesizer

A sound begins as a ripple, then rises into something massive—layered, animated and impossible to ignore. Leviasynth Keyboard is built for that kind of sonic transformation, combining 16 voices, eight oscillators per voice and a hybrid digital/analog signal path into a flagship instrument designed for deep sound design and commanding performance. Its algorithmic synthesis engine includes 300+ waveforms, 140+ preset algorithms, Custom Algorithm mode and algorithm morphing, while dual filter stages pair 18 digital filter models with analog 4-pole low-pass filtering and pre-drive saturation. Add 13 envelopes, five LFOs, a 32-slot modulation matrix, Polytouch polyphonic aftertouch, a 4-octave ribbon controller, a three-track sequencer and extensive MIDI/CV connectivity, and Leviasynth becomes a powerful creative system for players ready to explore the farthest reaches of synthesis.

Algorithmic Hybrid Synthesis With Eight Oscillators Per Voice

Leviasynth begins with a massive 16-voice engine built around eight oscillators per voice and a wide range of synthesis types, including Phase Modulation, Linear Frequency Modulation, Pulse Width Modulation, HTE Sync and three forms of Phase Distortion. More than 300 waveforms and 140+ preset algorithms provide a deep foundation for creating everything from thundering basses and cutting leads to glassy keys, brass-like tones and evolving atmospheres. Custom Algorithm mode lets you design your own oscillator routing and store it within a patch, while algorithm morphing allows smooth movement between eight selected algorithms. This gives the instrument a sound-generation architecture that is both technically expansive and highly musical.

Digital Filters, Analog Warmth and Deep Voice Control

After the oscillator engine, Leviasynth Keyboard routes sound through a flexible filter architecture that combines 18 digital filter models with a custom analog 4-pole low-pass filter. The digital section includes morphing and drive options for complex tonal shaping, while the analog pre-drive circuit and resonant filter add warmth, saturation and physical weight. Voice features such as Vintage mode, bit-depth control, OSC Stereo mode and Analog Feel allow you to shift the character from clean and precise to drifting, glassy or aggressively raw. Multiple polyphony modes, binaural stereo voice pairing, Glide and Glissando further expand how the instrument responds under the hands.

Modulation Designed for Constant Motion

Movement is central to Leviasynth, with 13 DAHDSR envelopes, five LFOs and a 32-point modulation matrix providing vast control over the sound engine. Each oscillator has its own dedicated envelope with looping, BPM-syncable stages, multiple trigger sources and quantization, giving complex patches detailed internal motion from the start. The LFOs include classic shapes, random and noise options, plus Step LFO mode for custom patterns and sequencer-like modulation. With 42 internal modulation sources, over 290 modulation destinations, VoiceMod offsets and eight Macros per part, Leviasynth gives sound designers the tools to create patches that shift, breathe and react in real time.

Polytouch Performance, Sequencing and Hands-on Control

The keyboard version of Leviasynth features an enhanced 61-key semi-weighted Polytouch keybed with polyphonic aftertouch, note-on velocity and note-off velocity for detailed expression. A 4-octave ribbon controller, illuminated pitch and modulation wheels and dedicated filter controls give players immediate access to expressive shaping during performance. The arpeggiator offers eight modes with Ratchet, Chance and Entropy functions, while the three-track sequencer provides two polyphonic note tracks plus one Macro automation track with up to 128 steps per track. With Drift, Probability and modulation-destination support for sequencer and arpeggiator parameters, performance patterns can evolve with the same depth as the synth engine itself.

A Flagship Instrument for Studio, Stage and Deep Exploration

Built into a tour-ready metal chassis, Leviasynth Keyboard is designed for demanding creative environments, with balanced TRS outputs, dual headphone jacks, MIDI In/Out/Thru, USB-B, CV Pitch, Gate, Clock, Mod inputs and Mod outputs for full studio and modular integration. The full-color touchscreen, Single/Multi mode controls, Upper/Lower part selection and ASM Manager patch software make editing, organization, backup and performance preparation efficient. With its hybrid synthesis engine, analog filtering, deep modulation, powerful sequencing and expressive Polytouch control, Leviasynth stands as a bold flagship instrument for musicians who want synthesis to feel vast, physical and alive.
