Product Description

The Hydrasynth is a multi-headed beast of a desktop synthesizer. Virtual analog eight-voice polyphony with 3 oscillators per voice immediately offers a huge sound out the box. It comes into its own when you introduce its unbelievably vast wave-morphing, filtering, assignable macro and effects features. And that’s just getting started…

Key features

  • Eight-voice polyphonic wave-morphing desktop synthesizer
  • 3 oscillators per voice, with wave-scanning on 1 & 2 (219 selectable waveforms)
  • 4 Mutators per voice, allowing FM, PWM, Sync, Harmonic scanning, and more
  • Versatile ring modulator and noise section with 5 complex LFOs
  • Two filters per voice (configure in parallel or series)
  • Filter 1 has 12 modes inc. LPG and Formant, filter 2 is classic state-variable 12dB/octave morphing filter
  • Arpeggiator with complex control options
  • Assignable Macro controls per patch, open-ended modulation matrix with up to 32 paths
  • Five looping DAHDSR envelopes with option for relating segment duration to current BPM
  • Integrated delay, reverb, and various modulation effects
  • CV & Gate I/O for easy integration into modular synth workflows
  • Global & per-module randomization and initialization always accessible straight on the front panel
  • 49-note keyboard with polyphonic aftertouch
  • Large ribbon controller for expressive performance control
  • OLED displays for waveform visualization and patch editing/performance display

Pushing the Boundaries of Synthesis

If you’re looking for a sound that’ll surprise, inspire and frighten you at every opportunity it gets, the Hydrasynth is ready and waiting. As mentioned earlier, its virtual analog 8-voice polyphony is already exciting – but it becomes a different beast entirely when you dive into its full capability.

Let’s start with the wave-morphing. With 219 waves to choose from, you’ve got plenty at your disposal. Oscillators 1 and 2 can morph waveshapes with mutators – 7 mutation processes to be precise. At this point, the possibilities seem endless.

But it doesn’t end there; two filters offer 12 modes in total, from LPG to 12dB octave-morphing. Then there’s the LFOs, 5 envelope generators, ring modulator, noise generator, mixer and effects (including modulation, ambience and more) so you can send your signal on whatever wild path you choose.

Tactile User Interface

With the keyboard version of the Hydrasynth, you get a 49-note keybed with polyphonic aftertouch. Not only is this is an excellent synth for connecting to external controllers and sequencers; it’s an all-encompassing performance instrument in its own right.

Combining the performable keyboard setup with the advanced arpeggiation, CV and filter controls, the Hydrasynth becomes an intuitive, tactile unit that lets creativity flow freely.

Finally, the Modulation Matrix offers 32 user-definable modulation routings are available for you to bridge 29 modulation sources and 155 modulation destinations. You can route the modulation in almost any direction, including the effects, arpeggiator and Modulation Matrix points.
