ASM Leviasynth Desktop Hybrid Algorithmic Synthesizer

The ASM Leviasynth Desktop is a powerful hybrid synthesizer designed for serious sound design, performance, and production. Combining advanced algorithmic synthesis with both digital and analogue filtering, it delivers an incredibly deep and flexible engine capable of creating everything from evolving textures to aggressive modern sounds—all within a compact desktop format.

Why choose the Leviasynth Desktop?

• 16-voice hybrid synth engine with 8 oscillators per voice
• Advanced algorithm-based synthesis with 144 preset configurations
• Hybrid filter design combining digital multimode and analogue low-pass
• Polyphonic aftertouch pads with Polytouch® technology
• Deep modulation system with 32-slot matrix, envelopes, and LFOs

Advanced synthesis engine with limitless potential

At the core of the Leviasynth is a highly flexible algorithmic engine where oscillators are arranged into configurable structures known as algorithms. With 144 preset algorithms and additional user-customisable options, you can define how oscillators interact using techniques such as phase modulation, frequency modulation, pulse width modulation, HTE sync, and multiple types of phase distortion.

Each oscillator features over 300 waveforms and seven independent modes, giving you exceptional control over tone creation. The addition of algorithm morphing unlocks an almost limitless range of oscillator configurations, making this a true playground for sound designers.

Hybrid filtering and powerful modulation

The Leviasynth blends a digital multimode filter with an analogue low-pass filter, complete with pre-drive saturation and self-oscillation. This hybrid design allows you to shape sounds with both precision and character, from clean digital textures to warm, driven analogue tones.

A comprehensive modulation system includes five envelopes, five LFOs, and a 32-slot modulation matrix, all freely routable. Each oscillator also has its own dedicated volume envelope, providing even deeper control over dynamic shaping.

Performance-focused workflow

The multi-colour touchscreen and intuitive interface make navigating the Leviasynth fast and efficient, whether you're building patches from scratch or tweaking presets in real time. The 16 Polytouch® pads offer polyphonic aftertouch and velocity sensitivity, delivering expressive performance capabilities that rival full-sized keyboards.

MPE compatibility further enhances expressive control, making the Leviasynth an ideal choice for modern performance setups.

Sequencing, arpeggiation, and sound management

The built-in three-track sequencer records both notes and macro automation, allowing you to create evolving patterns and complex arrangements. The arpeggiator includes an Entropy function for advanced 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 immediate access to a wide palette of sounds created by world-class designers. The included ASM Patch Manager for Mac and PC makes it easy to organise patches and keep firmware up to date.

Flexible performance modes

Single mode provides full 16-voice polyphony for maximum depth per patch, while Multi mode splits the engine into two 8-voice parts for layering and splits. This flexibility makes the Leviasynth equally suited to studio production, live performance, and complex sound design setups.

Ideal for

• Sound designers looking for deep, modular-style synthesis
• Producers creating modern electronic, ambient, or experimental music
• Performers needing expressive control with polyphonic aftertouch and MPE
• Studios wanting a versatile hybrid synth with extensive modulation
