ASM Hydrasynth Keyboard 49-Key Wave Morphing Synthesizer - Black

Notes swell, shift and evolve independently beneath your fingertips, turning every chord into something alive and reactive. That experience is at the core of the ASM Hydrasynth Keyboard, a performance-focused wavemorphing synthesizer built around polyphonic aftertouch, deep modulation and an extraordinarily flexible sound engine. With three oscillators, dual Mutants, dual filters and an extensive modulation matrix, it moves effortlessly from lush cinematic textures and expressive leads to aggressive basses and experimental sound design. Add the Polytouch keybed, 4-octave ribbon controller, onboard macros and extensive MIDI/CV integration, and the Hydrasynth becomes more than a synthesizer—it becomes a deeply expressive instrument designed for modern performers, producers and sound designers.

Polytouch Expression and Performance Control

At the center of the playing experience is ASM’s proprietary Polytouch keybed, delivering true polyphonic aftertouch for independent expression on every note. Unlike traditional aftertouch systems that affect all notes equally, Polytouch allows pressure changes to shape individual notes within a chord, creating far more dynamic and organic performances. The semi-weighted 49-key design feels responsive and familiar, while the 4-octave ribbon controller expands expression even further with pitch, modulation and Theremin-style control modes. Together with ergonomically designed pitch and modulation wheels, the instrument encourages fluid, highly tactile interaction during both studio sessions and live performance.

Advanced Wavemorphing Synthesis Engine

The Hydrasynth’s synthesis architecture is built for deep sound creation without sacrificing immediacy. Three oscillators provide access to 219 single-cycle waveforms, while oscillators 1 and 2 feature ASM’s WAVELIST wavemorphing system for building and scanning through custom waveform sets. Dual Mutants per oscillator introduce powerful processing methods like FM, hard sync, WavStack detuning, harmonic sweeping and advanced pulse-width manipulation, dramatically expanding the tonal palette. Combined with dual filters that can operate in series or parallel—including ladder, SEM-style, vocal and low-pass gate models—the instrument delivers a huge range of tones from warm and musical to aggressive and experimental.

Massive Modulation and Sound-Shaping Potential

Built for evolving, animated sounds, the Hydrasynth includes five advanced LFOs, five DAHDSR envelopes and a 32-slot modulation matrix with 35 sources and 191 destinations. LFOs can function as rhythmic step sequencers or looping modulation sources, while envelopes can loop and sync to tempo for constantly shifting textures. Macros allow dramatic transformations with a single gesture, and modulation extends throughout nearly every part of the synth engine—including effects and arpeggiator parameters. Despite the depth of the architecture, OLED displays, workflow shortcuts and dedicated controls keep sound design immediate and approachable.

Studio Integration and Expanded Connectivity

The Hydrasynth integrates seamlessly into modern production environments with extensive MIDI, USB and CV/Gate connectivity. Support for Eurorack, Buchla and multiple CV standards allows it to interact naturally with modular systems, while MPE support and MIDI automation capabilities make it equally powerful within DAW-based workflows. Balanced stereo outputs, dual headphone jacks and pedal inputs expand its flexibility for studio and stage applications. Whether used as the centerpiece of a hybrid setup or integrated alongside other synths and controllers, it adapts easily to a wide range of creative environments.

A Modern Synthesizer Built for Endless Exploration

Every aspect of the Hydrasynth is designed to encourage experimentation, from instant patch randomization and Favorites browsing to assignable macros and high-quality onboard effects modeled after sought-after studio processors. With 1,024 patch locations, advanced modulation options and a sound engine capable of both subtle nuance and total sonic transformation, it offers virtually limitless creative potential. Housed in a rugged steel-and-aluminum chassis and engineered for expressive performance, the ASM Hydrasynth kKeyboard stands as a forward-thinking synthesizer built for musicians who want their instrument to respond as dynamically as their ideas.
