Product Information

The HYDRASYNTH Keyboard is both a sound designer’s dream synth and a performing musician’s ideal. The sound engine is designed for maximum flexibility and power, while the user interface was crafted for simplicity and instant access. Its many workflow shortcuts let you edit a patch quickly with a minimal amount of paging.

​With an advanced wavetable synthesis engine, 3 Oscillators, dual Wave Mutants, and 2 filters that can be configured in series or parallel, the tone generating capabilities are unmatched.

As for performance capabilities, the Hydrasynth Keyboard has our proprietary Polytouch® keybed with polyphonic aftertouch. This provides a level of expressive, per-note control found only in certain vintage synths.

Add to this a 4-octave ribbon controller and ergonomically-designed pitch and mod wheels, and you have expression and control that are unequalled by any other hardware synthesizer on the market.

Features

Ribbon Controller

Add powerful expression to any patch using our 4-octave Ribbon Controller, which is perfectly situated above the keyboard. It can be used as a freely assignable modulation source, a pitch bend control, or even as a monophonic instrument!
This is possible thanks to our Theremin mode, which uses the ribbon to trigger a note. You can choose continuous pitch operation or quantize the ribbon to one of 60 scales, including microtonal scales. And if that's not enough, the ribbon can also be used as a CV source to control a Eurorack system!

Oscillators

The tone generation capability is the heart of any synthesizer, and the 3 Hydrasynth oscillators are alive with potential.
Each of the oscillators lets you choose from a selection of 219 single-cycle waveforms. And on top of that, two of the oscillators have powerful wavemorphing capabilities.
Wavemorphing is a feature usually found on synths with preset wavetables. But creating user wavetables on those products is arduous or downright impossible. Unlike most wavetable synths, our oscillators 1 & 2 have our easy-to-use WAVELIST mode.
This mode lets you select any 8 waves from our diverse collection of 219 waves, arrange them in the order you want, and then morph from one wave to another. This can be done automatically with any modulation source, such as an LFO or an envelope, or manually with a physical control such as polyphonic aftertouch or a Macro.
And now in version 2.0 you can choose the bit depth of each oscillator, which puts those sought-after vintage or grungy sounds at your fingertips.

Mutants

Oscillators 1 & 2 are routed into our MUTANTS. The Mutants allow you to modulate, bend and sculpt the sound in new (and old) ways.
Each Mutant lets you choose from the following processes:
  • FM-Linear: This is for making classic FM sounds. Choose multiple FM sources, including external inputs.
  • WavStack™: Creates 5 copies of the input source and allows you to set a detune amount.
  • Osc Sync: This gives you those classic hard sync sounds. Try hard-syncing a morphing wavetable for some fun.
  • Pulse Width Modulation (PW-Orig): Performs the classic pulse width modulation on any waveform.
  • PW-Squeeze: Compresses the center section of the waveform, for a unique type of PWM.
  • PW-ASM: Divides the incoming wave into 8 slices and lets you set the amount of FM that is applied to each segment. This is FM unleashed.
  • Harmonic Sweep: This will sweep the harmonics of the input source.
  • PhazDiff: Generates the difference of the incoming wave and a version that is inverted and phase-shifted.
The Mutants can also generate their own waveforms in both FM and Sync modes so you don't have use another oscillator. Of course the routing is flexible so you can choose the other oscillators as mod sources if you like.

The 3 Oscillators are fed into a mixer along with the Noise generator and Ring Modulator.
The mixer gives you independent control over the levels and stereo positions of those 5 sources.
After this you are able to choose how much signal from each source is routed to filters 1 and 2.
The filters can be routed in parallel or series for ultimate flexibility.
Who knew that a simple mixer could be so powerful? Well, in all humility, we did.
