Description
The ASM Leviasynth 61 Key Synth is a powerful hybrid algorithmic synthesizer built for serious sound designers and expressive players. With 16 voices, 8 oscillators per voice, dual analogue and digital filters and a deep modulation matrix, it offers vast sonic potential, from evolving cinematic textures to cutting-edge electronic tones. A 61-note Polytouch polyphonic aftertouch keybed, four-octave ribbon controller and full MPE compatibility put expressive performance at the heart of the instrument, while the colour touch screen and intuitive interface make complex patch creation feel fast and musical.
Under the hood, Leviasynth combines over 300 waveforms per oscillator, 7 oscillator modes and 144 preset algorithms with powerful algorithm morphing, letting you sculpt unique timbres that move and transform in real time. A three-track sequencer with macro automation, advanced arpeggiator with Entropy and a comprehensive effects section give you everything you need to create complete, polished sounds inside the synth. With generous patch storage for both Single and Multi modes and tight integration via the free ASM Patch Manager, Leviasynth is ready to become the centrepiece of your studio or live rig.
Hybrid Algorithmic Powerhouse
Leviasynth is built around a hybrid engine that blends digital flexibility with analogue character. Each of the 16 voices hosts 8 oscillators, which can be arranged into algorithms that define how they interact. With 144 preset algorithms and a custom slot per patch, plus algorithm morphing, you can move seamlessly between complex configurations for constantly shifting, animated sounds. Over 300 waveforms per oscillator and 7 independent oscillator modes, including Phase Modulation, Frequency Modulation, Pulse Width Modulation, HTE Sync and multiple Phase Distortion types, give you an enormous palette for everything from glassy pads to aggressive basses.
Expressive Polytouch Keybed and Ribbon
The 61-note ASM Polytouch keybed with polyphonic aftertouch lets you shape every note individually with pressure, opening up expressive control over filter sweeps, vibrato, timbre and more without needing extra controllers. Combined with the four-octave ribbon controller, pitch bend and mod wheel, Leviasynth encourages a hands-on playing style where performance gestures become an integral part of the sound. MPE compatibility means it also slots straight into modern expressive controller setups and DAWs.
Deep Modulation and Sequencing
Leviasynth offers serious modulation depth for intricate, evolving patches. Each of the 8 oscillators has its own volume envelope, on top of 5 additional envelopes and 5 LFOs per voice, all tempo syncable and freely routable via a 32-slot modulation matrix. The three-track sequencer records both notes and macro automation, so you can capture complex movements and parameter changes as part of your patterns. The arpeggiator adds another creative layer, with multiple modes and an Entropy function for advanced real-time note manipulation that keeps sequences fresh and unpredictable.
Analogue Warmth, Digital Precision and Studio Effects
A Hydrasynth-style digital multimode filter works alongside a 4-pole analogue low-pass filter with pre-drive saturation and self-oscillation, giving you everything from precise, surgical filtering to warm, driven resonance. Two insert effects and two master effects slots provide a full suite of processing including chorus, flanger, rotary, phaser, lo-fi, tremolo, EQ, compressor, distortion, multiple delays and reverbs. This integrated effects engine lets you finish sounds inside the synth, whether you are designing spacious ambient patches or tight, punchy leads.
Key Features
- 16-Voice Hybrid Algorithmic Engine – Each voice features 8 oscillators with over 300 waveforms and 7 oscillator modes, arranged into powerful algorithms that define how they interact. This gives you an immense range of tonal possibilities, from subtle motion to wildly complex, evolving textures.
- Polytouch Polyphonic Aftertouch Keyboard and Ribbon – The 61-note Polytouch keybed and four-octave ribbon controller provide highly expressive control over your sound. You can shape each note individually with pressure and gestures, making Leviasynth ideal for dynamic live performance and nuanced studio work.
- Advanced Modulation, Sequencer and Arpeggiator – With envelopes for every oscillator, 5 additional envelopes, 5 LFOs and a 32-slot modulation matrix, Leviasynth excels at complex modulation. The three-track sequencer with macro automation and the arpeggiator with Entropy and extensive variables let you generate intricate patterns and evolving phrases directly from the instrument.
- Dual Filters and Comprehensive Effects – A digital multimode filter and analogue 4-pole low-pass filter, plus two insert and two master effects slots, give you near-infinite tone shaping. From warm, saturated analogue-style sweeps to precise digital sculpting and studio-grade effects, you can craft fully produced sounds without leaving the synth.
