ASM Leviasynth Keyboard B Stock

New Hybrid Benchmark in the ASM Galaxy

The "Leviasynth Keyboard" continues ASM's innovation legacy by combining highly configurable digital oscillators with dedicated analog filtering circuitry. It carries forward the spirit of the Hydrasynth-style multimode filter while introducing a novel algorithmic approach designed to accelerate the creation of complex and evolving timbres.

For Demanding Creators, from Stage to Studio

Designed for sound designers, electronic, techno, ambient, synthwave, or film music producers, this 61-note keyboard shines both in the studio and live. Polyphonic aftertouch, the 4-octave ribbon, and MPE support offer rare expressiveness, ideal for moving textures, cutting leads, or cinematic pads.

Features and Innovations

At its core, an algorithmic engine where the 8 oscillators per voice are arranged into "algorithms" defining their interactions (PM, FM, PWM, HTE Sync, three types of phase distortion). Beyond 144 ready-to-use algorithms, each patch can include a custom algorithm and benefit from algorithm morphing to smoothly transition between configurations. Each oscillator offers over 300 waveforms and a dedicated volume envelope, complemented by 5 envelopes and 5 LFOs per voice, fully modulatable via a 32-slot modulation matrix.
On the processing side, a dual filter stage combines a Hydrasynth-style digital multimode filter and a 24 dB/oct analog low-pass filter with pre-drive and self-oscillation. Two insert effects and two master effects, along with a wide range of delays and reverbs, shape the sound from subtle sculpting to radical design.
Performance is supported by a 3-track sequencer (notes + macro automation) and an arpeggiator featuring the Entropy function for real-time variations. In Single mode, 16 voices are dedicated to one patch; in Multi mode, they split into two 8-voice parts with layers/splits. The multicolor touchscreen and ASM Patch Manager (Mac/PC) simplify editing, updates, and sound management.
