A Milestone in Modern Digital Synthesizers
The ASM HYDRASYNTH has established itself as a benchmark in digital synthesizers thanks to its flexible wavetable engine and an interface designed for speed. Firmware 2.0 consolidates this position by expanding memory, deepening modulation, and smoothing live performance.
Who It's For and What It's For
Ideal for sound designers, electronic producers, and stage keyboardists, the HYDRASYNTH excels in evolving textures, expressive leads, and cinematic pads. Its polyphonic aftertouch and ribbon controller transform every nuance of playing into musical control.
Key Features for Creation and Performance
Expressive Playing Experience
The Polytouch keyboard offers rarely seen per-note control, while the 4-octave ribbon (Theremin mode) invites spectacular glissandi and morphings. Firmware 2.0 adds increased vibrato resolution and new sustain pedal options, including "Sostenuto," for finer articulation.
Evolving Sound Engine
Three oscillators and 219 single-cycle waveforms power Wavescan, Wavelist, and waveform morphing. The mixer includes noise generator and ring modulator, and two wave mutators sculpt harmonics before entering a versatile filter section (ladder, HP, LP, vocal, SEM-style, etc.).
Accelerated Modulation and Workflow
With 5 DAHDSR envelopes, 5 advanced LFOs, and a clear modulation matrix, everything is designed for experimentation. Firmware 2.0 introduces "Voice Modulator," an oscillator bit reducer, LFO and ENV quantizers, "LFO Step Advance," more Rand/Init shortcuts, and global effects bypass. Expanded LED options and saved "Local On/Off" optimize live use even further.

Questions frequently asked
Does the Hydrasynth keyboard feature polyphonic aftertouch?
The Polytouch keyboard transmits per-note control through polyphonic aftertouch. The 4-octave ribbon, usable in Theremin mode, allows for glissandi and morphing.
How many oscillators and waveforms are available?
The synthesis engine is based on three oscillators and 219 single-cycle waveforms. Wavescan, Wavelist, and morphing modes enable evolution of these waveforms. Two wave mutators act before the filter section.
What filters are integrated?
Filter 2 offers a 12 dB per octave SEM-type slope, with continuous sweep between high-pass, band-pass, and low-pass modes.
What does firmware 2.0 bring to the ASM Hydrasynth Keyboard?
Version 2.0 expands memory and adds features including Voice Modulator, oscillator bit reduction, and quantizers for LFO and envelope. Sustain options including Sostenuto and a global effect bypass are also included.
What are the dimensions and weight of this synthesizer?
With dimensions of 800 x 350 x 103 mm, this model maintains a format suitable for stand or studio setup. It weighs 10 kg.
