Warp Core Stereo Phase Distortion Oscillator Is Down With The Thiccness

Infrasonic Audio let us know that a limited run of Warp Core – a stereo/dual-output complex oscillator for Eurorack – is now available.


  • Unlike traditional oscillators, Warp Core is not designed to produce perfect geometric wave shapes (triangle, saw, square, etc), but instead uses phase distortion to produce variably complex waveforms, with rich harmonic content from a pure sine wave lookup table.
  • The phase distortion engine features 8 different continuously variable algorithms assignable to two slots routed in series, for a total of 64 possible combinations. Because these algorithms are almost all nonlinear, in most cases different timbres will be produced when swapping the order of the selected algorithms.
  • Warp Core also features phase modulation pre- or post- phase distortion via an internal sine modulation oscillator with a configurable frequency ratio relative to the main oscillator. For even more phase modulation possibilities, there is also an audio-rate external PM input.
  • Two configurable “thickness” parameters serve to reinforce the fundamental and/or sub-octave of the oscillator output and provide slight detuning on the 90° output for thicker stereo or unison sounds.
  • Warp Core’s calibrated tuning controls enable quickly and easily tuning the oscillator to arbitrary frequencies or perfectly tuned (A=440Hz 12-TET) semitones in multiple octaves, as well as locking the tuning knob to preserve perfect tuning for a live performance.
  • For even more utility, the WC:EX Expander gives you the option to convert Warp Core from a free-running oscillator to a dedicated PD/PM monophonic synth voice, with an envelope generator, internal VCA, and smart CV normalizations to shape your sound – all in just 4hp.

Pricing and Availability:

Warp Core is available now, priced at $375. The WC:EX Expander is $80.

    1. I think it’s fine (even helpful) to take some obv design inspiration from a module everybody knows, especially because the functionality is very different/unfamiliar

    2. Having used one, the interface is really straightforward. The led selection is makes it really clear what mode you’re in. I can’t compare to the popular modular, since I never had that one *gasp*
