ASM Leviasynth Keyboard 61-Key Hybrid Algorithmic Synthesizer

The ASM Leviasynth Keyboard takes advanced sound design and expressive performance to another level. Combining a powerful hybrid synthesis engine with a 61-note Polytouch® polyphonic aftertouch keybed and ribbon controller, it delivers deep sonic control alongside a highly playable and performance-ready interface.

Why choose the Leviasynth Keyboard?

• 16-voice hybrid engine with 8 oscillators per voice
• 61-note Polytouch® keybed with polyphonic aftertouch
• 4-octave ribbon controller for expressive performance
• Advanced algorithm-based synthesis with morphing capabilities
• Hybrid filter design with analogue low-pass and digital multimode

Deep algorithmic synthesis engine

At the heart of the Leviasynth is a powerful algorithm-based synthesis system. Oscillators are arranged into structures known as algorithms, defining how they interact and shape sound. With 144 preset algorithms and additional user-configurable options, you can explore a huge range of synthesis methods including phase modulation, frequency modulation, pulse width modulation, HTE sync, and multiple types of phase distortion.

Each of the eight oscillators per voice features over 300 waveforms and seven independent modes, delivering exceptional timbral flexibility. Algorithm morphing further expands the sonic possibilities, allowing for near limitless variations in oscillator behaviour.

Hybrid filtering and advanced modulation

The Leviasynth combines a digital multimode filter with an analogue low-pass filter, complete with pre-drive saturation and self-oscillation. This hybrid architecture allows for precise shaping alongside rich analogue character.

A powerful modulation system includes five envelopes, five LFOs, and a 32-slot modulation matrix, all freely assignable. Each oscillator also features its own volume envelope, giving you detailed control over dynamics and movement within your patches.

Expressive performance control

The 61-note Polytouch® keybed provides polyphonic aftertouch for expressive playing, while the four-octave ribbon controller adds another layer of real-time control. Combined with MPE compatibility, the Leviasynth Keyboard is built for musicians who want maximum expression in both studio and live performance environments.

The multi-colour touchscreen and intuitive interface make navigating complex sound design fast and accessible, keeping you focused on creativity rather than menus.

Sequencing, arpeggiation, and workflow

The built-in three-track sequencer captures both note data and macro automation, making it easy to create evolving patterns and full arrangements. The arpeggiator includes an Entropy function for dynamic real-time note variation, adding movement and unpredictability to your performances.

With 512 factory patches in Single mode and 256 in Multi mode—plus extensive user storage—you’ll have access to a wide palette of professionally designed sounds straight out of the box.

Flexible performance modes

Single mode utilises all 16 voices for maximum depth and complexity, while Multi mode splits the engine into two 8-voice parts for layering and splits. This flexibility makes the Leviasynth equally suited to performance, production, and advanced sound design workflows.

Ideal for

• Sound designers needing deep, flexible synthesis capabilities
• Performers who want polyphonic aftertouch and expressive control
• Producers creating modern electronic and experimental music
• Studios looking for a powerful hybrid hardware synth
