Build complex sounds from the ground up
The Leviasynth sound engine centres around eight oscillators per voice, each with access to over 300 waveforms and seven oscillator modes. These oscillators are grouped into algorithms that define how they influence each other, opening up detailed harmonic and textural control.
With 144 preset algorithms plus a user-definable option per patch, there is plenty of scope to experiment. Algorithm morphing lets you move smoothly between configurations, which is especially useful for evolving pads, animated leads, and shifting soundscapes. Each oscillator has its own envelope, supported by additional shared envelopes and LFOs, all routed through a clear 32-slot modulation matrix.
Shape tone with hybrid filtering and effects
Hybrid filtering gives you both precision and character. The digital multimode filter offers a wide selection of responses, including low-pass, band-pass, high-pass, and more specialised types, while the analogue four-pole low-pass filter adds weight and natural saturation. Pre-drive and self-oscillation expand sound design options without needing external processing.
Effects are integrated directly into the engine, with insert and master stages covering modulation, dynamics, distortion, delay, and reverb. This setup keeps everything contained, making it easy to finish sounds inside the instrument rather than relying on outboard gear or plug-ins.
Play with detail and expression
ASM’s Polytouch polyphonic aftertouch keyboard responds to individual finger pressure, so you can shape timbre, filter movement, or modulation per note. This makes chords feel alive rather than static. The ribbon controller adds another layer of control for pitch bends, transitions, or modulation sweeps, and it works smoothly alongside traditional wheels.
MPE support ensures compatibility with expressive controllers and modern DAW workflows. These performance tools encourage hands-on interaction, helping ideas develop naturally during rehearsals, recording sessions, or live sets.
Stay organised in studio and live setups
Single and Multi modes make the Leviasynth flexible in different situations. Single mode dedicates all 16 voices to one patch, ideal for rich textures or complex sequences. Multi mode splits the voices into two parts, making layers and keyboard splits straightforward to set up.
A three-track sequencer records notes and macro automation, while the arpeggiator includes an Entropy function for controlled variation. With extensive preset storage and free ASM Patch Manager software for updates and organisation, managing sounds stays simple as your library grows.
