Rare Waves Hydronium Eurorack - Silver

Rare Waves Hydronium is a great-sounding analog synthesizer with MIDI and CV-Gate control. It was introduced in 2019, created and supported by Eric Archer behind the Grendel brand.

This listing is for the pre-assembled Eurorack version in silver (natural) brushed aluminum. (Not a DIY kit). This unit is fully tested, set up correctly, and ready to make music out of the box!  It can be played from either your MIDI controller or CV-Gate sequencer (1V/oct).

Hydronium Eurorack module is 28HP width [142 mm] and has 32 mm depth behind the rails. M3 screws included.

Price Includes free shipping by USPS Priority Mail. This listing ships to USA only.

About the synthesizer:

The Rare Waves Hydronium is a semi-modular synthesizer with unmistakable true analog tone. Its array of twelve patch points can interconnect with other analog synthesizers to inspire your music deeper and further in the creative zone.

While it is designed to operate similar a TB-303 inspired acid synth, Hydronium is not a clone circuit. Its tone is based on a single VCO, a state variable low-pass filter with adjustable resonance, and a decay envelope with MIDI velocity sensitivity. And as you’d anticipate of any acid synth, it has MIDI-programmable glide (pitch slide) and dynamic accents for individual notes.

With CV-Gate control, this synth uses Velocity CV (0..5V) instead of Accent Gate. Set the DYNAMICS knob to max and use the Velocity CV for dynamic variation. Legato phrases are automatically detected as pitch slides, so it doesn't have a Slide Gate input.

Hydronium’s classic tone is a natural choice for sequenced basslines. Switch the envelope to gate mode, and it also serves as a lead synthesizer when you need a bright, clean sawtooth or pulse waveform in the mix.

It can be played either by MIDI control or CV-Gate. In addition, its built-in MIDI-to-CV converter with post-glide v/oct output lets you use it as a bridge between your MIDI controller and other analog synthesizers.

Hydronium features an audio effects loop that is positioned between its filter and VCA. This is a good place for distortion effects, phaser, and certain other effects that tend to increase the noise floor when patched to a synth’s line out. The pre-VCA effect return silences the self-noise from the effect, preserving full dynamic range even when you bend its tone with a high-gain fuzz pedal, for example.
