Essential Information About the ASM Leviasynth Desktop Synthesizer
- Massive Polyphony and Algorithmic Engine: 16 voices, 8 oscillators per voice, 300+ waveforms, 7 oscillator modes, and algorithm morphing for an almost infinite sonic palette.
- Dual Hybrid Filtering: Digital multimode filter "Hydrasynth style" + 4-pole analog filter with pre-drive saturation and self-oscillation for ultra-expressive timbres.
- Highly Expressive Control: 16 Polytouch pads with polyphonic aftertouch, MPE compatibility, color touchscreen, and an interface designed for rapid patch creation.
- Integrated Production: 3-track sequencer with macro automation, "Entropy" arpeggiator, 32 modulation slots, 2 insert + 2 master effects, and advanced patch management.
A New Chapter in the ASM Range
Designed to extend ASM's innovative DNA, the Leviasynth Desktop combines algorithmic power and analog character in a compact format. Its Hydrasynth-type digital filter meets a true analog low-pass filter, while the multicolor touch interface and Polytouch pads bring modern ergonomics tailored for performance and sound design.
Who Is It For and What For?
Ideal for sound designers, producers of electro, techno, ambient, or synthwave, as well as pop and film scoring. Beginners benefit from inspiring sound engines and clear macros, while advanced users exploit the modulation matrix, algorithms, and Multi mode for splits/layers both live and in the studio.
Features and Innovations
The
hybrid algorithmic engine stacks 8 oscillators per voice, organized into
144 algorithms (one user-customizable algorithm per patch) with
Algorithm Morph. Each oscillator draws from 300+ waveforms and 7 modes, with PM, FM, PWM, HTE Sync configurations, and three types of phase distortion. On the modulation side, each oscillator has its own volume envelope, in addition to
5 envelopes and
5 LFOs per voice, routable through a
32-slot matrix.
The
digital multimode filter pairs with a
24 dB/oct analog LP filter (pre-drive and self-oscillation) for advanced tonal shaping, complemented by two
insert effect slots and two
master effect slots (chorus, flanger, phaser, rotary, distortion, EQ, compressor, delays, reverbs...). The
3-track sequencer records notes and macro automation, and the arpeggiator introduces the
Entropy variable for organic rhythmic variations.
The
16 Polytouch pads with polyphonic aftertouch and
MPE compatibility offer ultra-expressive playability. In
Single mode, all 16 voices are dedicated to one patch; in
Multi mode, two parts of 8 voices allow splits and layers. Preset management is smooth via the ASM Patch Manager (Mac/PC), with 512 factory Single presets and 256 Multi presets, and a total of 1024 Single + 640 Multi slots.
