Transfiguration Oscillator Eurorack Module

US EarthQuaker Devices releases The Wave Transformer      18/01/24

EarthQuaker Devices says that they are diving deeper into the weird and wonderful world of modular synths, by creating a complex single oscillator module with seven audio outputs, a host of exciting features, and a unique "wave transformation" circuit, all for a modest price.

Joshua Kolenc, IT Systems Administrator at EarthQuaker Devices and designer of The Wave Transformer, told us, "I have always been fascinated by metamorphosis, transmutation, transformation, transfiguration, and morphology. As such, I was working on an effects routing device that could morph a signal path by rearranging the order of effects by turning a single knob. This journey led me down the path to realizing the novel wave shaping circuitry found within The Wave Transformer."

The Wave Transformer's method of wave shaping differs from other complex oscillators in that it is not based upon classic wave folding, as is common in West Coast synthesis, or filtration as is common in East Coast synthesis. Rotating the Transform control will vary the Complex output from a simple waveform to a complex, gnarled mass of audio mutations.

You can yield countless variations on these mutations by combining this novel circuit with Hard Sync, Soft Sync, Linear FM and Exponential FM. Additionally, you can mute the source waveform to use the circuit as a harmonic gate/VCA, rendering The Wave Transformer a voice unto itself. If that's not enough, there is a Shape Insert that allows you to transform external oscillations and modular-level audio sources.

The Wave Transformer comes with a lifetime warranty and is available now at Eurorack and EarthQuaker Devices dealers worldwide.
