The ASM Leviasynth Keyboard is a 16-voice hybrid algorithmic synthesizer with eight oscillators per voice, dual analogue and digital filtering, advanced modulation, and performance controls that merge classic synthesis principles with contemporary expressive technologies. The Leviasynth builds its sound around an algorithmic engine where eight oscillators per voice interact through structured algorithms rather than simple layering, allowing complex internal modulation, feedback, and spectral movement. With an architecture this deep paired with one of the most expressive keybeds available, the Leviasynth is nothing short of a sound designer's dream.

Key elements of its design:

• Hybrid Algorithmic Engine ASM implements 144 preset algorithms alongside one user-customisable algorithm per patch, while real-time algorithm morphing enables continuously variable oscillator relationships instead of static routings. Each oscillator accesses over 300 waveforms and seven independent oscillator modes, including phase modulation, frequency modulation, pulse width modulation, HTE sync, and three distinct phase distortion models.
• Dual-Filter Topology The Leviasynth employs a dual-filter topology that pairs a digital multimode filter with a true analogue low-pass filter. The analogue filter delivers a 24 dB per octave response with pre-drive saturation and self-oscillation, enabling both smooth warmth and resonant leads, while the digital filter provides 18 models ranging from classic LP/BP/HP types to emulations such as MS20, Steiner-Parker, and vowel filtering.
• Extensive Modulation System The Leviasynth offers 13 DAHDSR envelopes with looping and BPM sync modes, five LFOs with sine, triangle, saw, ramp, square, random, noise, and step shapes, and a 32-slot modulation matrix with 170 sources and 425 destinations. Each oscillator also carries its own dedicated volume envelope, and LFOs feature a custom step mode allowing them to double as independent step sequencers or custom waveshapes.
• Polytouch® Polyphonic Aftertouch Keybed The 61-note Polytouch polyphonic aftertouch keybed together with the 4-octave ribbon controller offers an unsurpassed playing experience, and the Leviasynth is also MPE-compatible. Additional performance controls include an illuminated Pitch Bend wheel, Mod Wheel, and Envelope Bias touch response.
• Comprehensive Effects The effects section includes 9 insert effects, 5 delays, and 4 reverbs, with types including Chorus, Flanger, Rotary, Phaser, Lo-Fi, Tremolo, and more.
• Sequencer, Arpeggiator & Macros The internal three-track sequencer records note, arpeggio, and macro automation data. The eight-mode arpeggiator features Ratchet, Probability, and Entropy controls, designed to work independently or together. Eight macro controls per part, each with eight individually assignable sources, provide immediate hands-on expressivity.
• CV/Gate & MIDI Connectivity 3.5 mm CV I/O provides two assignable Mod inputs as well as outputs for Pitch, Gate, Clock, and two assignable Mod outputs for integration with Eurorack systems. The Leviasynth also includes balanced stereo outputs, dual headphone sockets with independent volume control, USB Type-B for MIDI and patch management, and full MIDI In, Out, and Thru.
• Patch Memory & Management A total of 1,024 patch locations for Single mode and 640 patch locations for Multi mode are available. The free ASM Patch Manager for Mac and PC enables easy firmware updating and patch management.
