Ashun Sound Machines’ Leviasynth is an immense 16-voice algorithmic synthesizerAshun Sound Machines dropped a new synth monster at NAMM 2026 with the Leviasynth. This epic instrument is packed with technological capability: a 16-voice digital/analogue hybrid synthesis engine with serious sonic prowess.
ASM’s Leviasynth is centred around its algorithmic sound engine, which features eight oscillators per voice across seven synthesis types and over 140 configurable algorithms. Two independent layers can be stacked or split, with voices pairing into true binaural stereo sets for wide, independently modulated soundscapes.
The Leviasynth’s signal path blends two filters: a Q-compensated 4-pole low-pass analogue filter with pre-drive saturation for extra grit, and a digital filter boasting 18 models with morphing and drive. The engine supports phase modulation, linear frequency modulation, pulse width modulation, HTE sync, and three types of phase distortion. There’s also 13 envelopes, five LFOs, a modulation matrix, per-voice modulation offsets, and a macro control — you can keep an eye on this all via the full-colour touchscreen display.

The arpeggiator has eight different modes, such as ratchet, chance, and entropy, with individual controls for mode, octave, and gate to create highly precise runs of notes. Its sequencer allows for a huge 128 steps per track with drift options to imbue that imperfect human feel.
To help cut down on the inevitable choice paralysis that comes with such a dense piece of gear, the Leviasynth offers over 140 presets along with the ability to build and save original presets.
MusicTech’s commissioning editor, Sam Willings, got hands-on with the Leviasynth at NAMM 2026, and says: “The Leviasynth dragged me into its vast sound palette at NAMM for a lot longer than I planned. Its massive bank of inspiring presets, intuitive interface, and three-track sequencer had me hooked for about 30 minutes straight, building pads, sequences and squelching basslines.”
The keyboard version has 61 Polytouch keys for expressive tactility when using the 16 voices, but both models sport the touch screen. Its price tag is $1,799 for the desktop version and $2,499 for the keyboard version.
