Electro-Harmonix has announced the Mod Rex Polyrhythmic Generator, a brand-new pedal that houses four independent modulation engines—Mod, Trem, Pan, and Filter—that contain a host of effects and tweakable parameters.

The Mod engine offers vibrato, flanger, chorus, and phaser, and includes a Depth and Feedback knob. The Trem modulates the amplitude of your signal. When the unit's stereo outs are used, Pan allows a wide separation of the left and right channels (but while in mono mode, it acts as another tremolo section). Finally, the Filter section gives the choice of low-, high-, and band-pass filters.

While each engine can operate on its own and be given one of nine distinct subdivisions of time—from a whole note to 16th notes—they're all synced to one master tempo. Through MIDI, this tempo can easily be synced to an external device. Users can choose between four LFO shapes for each engine (rising sawtooth, triangle, falling sawtooth, or square wave) for further sonic differentiation.
