Introducing the ASM Leviasynth

New Hybrid Algorithmic Synthesizer available in keyboard and desktop formats

Published 22nd January 2026

ASM introduces Leviasynth, a new hybrid algorithmic synthesizer, available in both Keyboard and Desktop versions. Offering 16 voices with 8 oscillators per voice and a combination of analog and digital filters, the Leviasynth is truly a sound designer’s dream synthesizer.

There are over 300 waveforms available for each oscillator, and 7 independent oscillator modes for maximum timbral diversity. The 3-track sequencer records both note and macro automation, and the arpeggiator features a new Entropy function for advanced realtime note manipulation.

Single mode allows for all 16 voices to be active per patch, and Multi mode allocates the voices into two parts of 8 voices each, where layers or splits are easily set up. The free ASM Patch Manager for Mac and PC enables easy firmware updating and patch management. 512 Single mode and 256 Multi mode patches are included in the factory presets, all created by world-class sound designers.

The multi-color touch screen and intuitive user interface make patch programming a breeze. The oscillators can be arranged in groups known as algorithms, which define how they affect each other. There are 144 preset algorithms available, and one additional algorithm can also be customized per patch. In addition, algorithm morph offers a nearly unlimited number of configurations for the oscillators.

Leviasynth – Core Features (Both Versions):

  • 16-voice polyphony
  • 8 oscillators per voice (300+ waveforms each)
  • 144 preset algorithms + one user-customisable algorithm per patch
  • 32-slot modulation matrix, 5 LFOs, 6 envelopes per voice
  • Algorithm Morph for continuously variable oscillator structures
  • Hybrid filters: digital multimode + analog 4-pole low-pass
  • 3-track sequencer (notes + macro automation)
  • Advanced arpeggiator with Entropy function
  • MPE compatible
  • ASM Patch Manager support (Mac & PC)

A total of 1024 patch locations for Single mode and 640 patch locations for Multi mode are available. Oscillator configurations include Phase Modulation, Frequency Modulation, Pulse Width Modulation, HTE Sync, and three types of Phase Distortion. Each of the 8 oscillators has its own volume envelope, in addition to the shared 5 envelopes and 5 LFOs, all freely routable in the powerful 32-slot modulation matrix. The digital Hydrasynth-style multimode filter and the analog low-pass filter, featuring both pre-drive saturation and self-oscillation, together with two insert effects and two master effects, make for near-infinite tone-shaping possibilities.
