Essential Information About the HYDRASYNTH Keyboard Synthesizer
- 49-key Polytouch keyboard with polyphonic aftertouch and 4-octave ribbon controller for exceptional expressiveness.
- Ultra-flexible hybrid wavetable/virtual-analog engine: 3 oscillators, 2 wave mutators, 2 filters in series/parallel.
- Deep and intuitive modulation: 5 DAHDSR envelopes, 5 advanced LFOs, extended modulation matrix.
- Creative arpeggiator, Pre/Post effects, MIDI/USB and CV/Gate connectivity for studio and stage.
The Modern Pillar of the ASM Range
Designed to revisit wavetable aesthetics with a decidedly modern approach, the HYDRASYNTH Keyboard stands as the versatile reference of the ASM series. Its direct interface, high-resolution encoders, and smart shortcuts offer a fast workflow, ideal for creating, editing, and performing without endless menus.
For Demanding Sound Designers, Keyboardists, and Producers
Whether you produce electro, techno, ambient, synthwave, pop, or film music, this synthesizer meets both the needs of precise sound design and the demands of live performance. Ambitious beginners and experts alike will appreciate its immediate playability, expressive polyphonic aftertouch, and full connectivity in modular studio setups.
Features and New Additions
The sound engine combines 3 oscillators with 219 waveforms, morphing, WaveScan, Wavelist mode, and wave mutators, all routed through two configurable filters to sculpt organic or futuristic timbres. The arpeggiator includes Ratchet, Chance, Gate, and Swing, while modulation (5 LFOs, 5 envelopes) opens a vast field for exploration. Firmware 2.0 notably adds memory expansion (up to 8 banks on 49-key/Desktop/Explorer models), the "Voice Modulator" modulation source, oscillator bitcrusher, LFO and envelope quantizers, LFO Step Advance, global effects bypass, higher-resolution vibrato, new pedal options including Sostenuto, glissando in glide, arpeggiator range extended to 6 octaves, arpeggiator Step Offset, expanded Rand/Init shortcuts, and Local On/Off save.
