MusicRadar called it long-anticipated: the Leviasynth, Ashun Sound Machines' successor to the Hydrasynth, unveiled at NAMM 2026 1. It comes in two forms, a 61-key keyboard and a desktop module 12.

The engine

The Leviasynth is a 16-voice instrument with eight oscillators per voice 12. Those oscillators can be grouped into algorithms that define how they modulate each other, which MusicRadar compares in principle to FM synthesis 1. ASM ships 144 preset algorithms, and Sound On Sound says you can also design, save and morph between your own 2. Each oscillator can draw on more than 300 waveshapes, and the synthesis modes include FM, PM, PWM, HTE Sync and three types of phase distortion 2.

The signal path is the hybrid part. A digital filter with 18 modes feeds a new analog four-pole resonant filter with pre-drive saturation and self-oscillation 2. Modulation runs through a 32-slot matrix with 170 sources and more than 290 destinations, per Sound On Sound 2.

The keyboard is the point

For composers who perform parts into a DAW rather than drawing them in, the hardware is the reason to look. The keyboard model has a 61-note Polytouch keybed with polyphonic aftertouch and a four-octave ribbon controller 12. The desktop version replaces the keys with 16 Polytouch pads 12. MusicRadar notes MPE compatibility 1.

Polyphony can be split, too. In Single mode one patch gets all 16 voices; Multi mode divides them into two eight-voice parts 1. There's a three-track sequencer that records macro and note data, an arpeggiator, and a new "Entropy" function for real-time note manipulation 1.

Price, shipping and firmware

The launch coverage disagreed on price, but retail has settled it. As of November 14, 2026, Sweetwater lists the keyboard at $2,499 and the desktop at $1,799, both in stock 34. That matches MusicRadar's launch figures 1. In a July update, Synth Anatomy reported it had been on the market for about six months, with the first discounts appearing at a European dealer 5.

The software has kept moving too. Firmware 1.2, a free download for existing owners, finishes the sequencer's entropy deviation engine, which generates variations from an existing pattern, per step or across all steps 5.

Round the back, Synth Anatomy lists a headphone output, two 6.3mm stereo outputs, sustain and expression pedal inputs, 5-pin MIDI in, out and thru, and USB-B 5, and Sweetwater adds CV/gate I/O to the list 3.
