With the Leviasynth Desktop, ASM (Ashun Sound Machines) introduces a 16-voice hybrid synthesizer with algorithmic engine synthesis. In terms of sound and functionality, the Leviasynth offers a range of unique features that are rare in this format. The 16 velocity-sensitive pads allow you to play sounds and program the sequencer, while the pad mode provides access to additional functions. The user interface is designed to minimize the need for menu diving, with most functions just a keystroke away. Eight encoders with LED rings and a touch display offer excellent control over all parameters and ensure a clear and intuitive overview.
Thanks to the chord function, three-track sequencer, and fully programmable arpeggiator, you have three powerful creative tools right at your fingertips for both live performances and studio work. In multi-mode, the Leviasynth 2-Part is multi-timbral (lower/upper), meaning you can play two different sounds simultaneously. Out of the box, the Leviasynth Keyboard offers a generous 1024 memory locations for sounds, plus an additional 640 memory slots for multi-programs.
A standout feature is the five analog control voltage outputs for CV, gate, clock, and two customizable controllers, making this synthesizer a perfect centerpiece for any modular setup.

The two filters form the heart of the hybrid synthesis architecture. First, the digital Multimode filter offers 18 types, including unique models like low-pass, band-pass, high-pass, notch, vintage classics, and even a vocal filter (Vowel). This is followed by an analog 24dB Lowpass filter with built-in overdrive. The overdrive adds a subtle punch to the sound, giving oscillator mixes, especially with classic waveforms, a lot more bite. The analog filter really enhances the overall tone.
With the oscillator section, ASM has given the Leviasynth a major selling point. The eight oscillators can be arranged in “algorithms” that define how they interact. There are 144 preset algorithms to choose from, and you can create a custom algorithm for each patch. Additionally, Algorithm Morph gives you the freedom to create almost any oscillator configuration. Over 300 waveforms and 7 independent oscillator modes are available for each oscillator, providing endless sonic possibilities. FM setups, oscillator sync, and noise also form part of the palette. In short, there’s much more here than just a few oscillators waiting to be adjusted.

When it comes to modulation, the Leviasynth truly delivers. It offers five LFOs and five envelopes for each voice; there are even eight separate envelopes dedicated to the eight oscillators. Plus, there’s an extensive modulation matrix with 32 slots and a randomizer. Modulation sources are available via the display and include eight macro controllers, a large ribbon controller, two control voltage inputs, illuminated handwheels for pitch bend and modulation, and the keyboard itself. In addition to pitch and note length, the keyboard generates velocity and polyphonic aftertouch. These extensive modulation options are rounded out with a full MIDI implementation, including MPE (MIDI Polyphonic Expression).
At the final stage of the signal chain, there are three effect blocks to add the finishing touch to your sound. Modulation effects like chorus, flanger, rotary, phaser, and tremolo, plus sound enhancers such as EQ, lo-fi, compressor, and distortion, are available as insert effects. Delay and reverb can be used simultaneously, with five variations of delay and four for reverb, offering you a wealth of creative options.
