Erica Synths has introduced Razornator, a new stereo resonator created in collaboration with Dutch plugin developer 112dB. Expanding the company’s desktop FX lineup alongside Nightverb, Echolocator, and Xenodrive, the unit is built around five chromatically tuned delay lines designed to produce pitched, harmonic resonances.
At its core is the Karplus-Strong algorithm, a physical modelling technique that simulates the resonant behaviour of plucked strings and other vibrating objects. The five resonators can be tuned to musical intervals or chord voicings, while an integrated envelope follower dynamically shifts their tuning according to the incoming signal.
The signal chain begins with an input gain stage capable of up to +24dB of analogue overdrive before passing through a resonant low-pass filter, the five resonators, a compressor, dry/wet mix control, and EQ. All 12 parameters can be stored as presets, controlled via MIDI, and the resonator pitches can be performed in real time. Preset morphing also allows smooth transitions between stored settings.
Housed in the same compact aluminium chassis as the rest of Erica Synths’ desktop range, Razornator features a true stereo signal path throughout and is available now for US$ 557.99.
