Electro-Harmonix Mod Rex Polyrhythmic Modulator Pedal

The Mod Rex Polyrhythmic Modulator Pedal from Electro-Harmonix is a kinetic tour de force of a pedal that lets you weave compelling, shifting, musical tapestries. It can be used by guitarists, synthesists, or electronic musicians to stretch musical boundaries and tailor sound for recording studio, live stage, and rehearsal applications.

Four Independent Modulation Sections

The heart of the pedal is its four, independent modulation sections synced in time.

Vibrato, Flanger, Chorus, or Phaser

The depth knob lets you set the amount of the effect, while feedback controls the resonance of the flanger and phaser.

Tremolo

An effect that modulates the volume of your signal. The depth control sets tremolo intensity.

Pan

Pan modulates between left and right in stereo operation. In mono operation, the pan section acts as another tremolo section, but with the wave shapes inverted.

Filter

Filter offers a choice of a modulated LPF, HPF, or BPF. In LPF (low-pass filter) frequencies above a modulated cutoff point are cut. In HPF (high-pass filter) frequencies below a modulated cutoff point are cut, and in BPF (band-pass filter) frequencies above and below a modulated center point are cut.

LFO Shape Options

Consists of rising sawtooth, triangle, falling sawtooth, or square wave. They affect the way the modulation transitions and provides advanced creative control over the specific section as well as the way they interact with each other.

Tempo Control That's Flexible

The Mod Rex delivers virtually limitless polyrhythmic possibilities. Its tempo component gives you nine note-length choices for each of the four modulation sections. They are independently selectable in increments starting at a whole note and ranging thru subdivisions that go up to a 16th note. In addition, any of the sections can be bypassed.The Mod Rex's tempo (displayed as beats per minute or BPM) is adjustable with the tempo knob, tap tempo footswitch or by using an expression pedal into its EXP input. It can also be synced to an external device with MIDI clock or an external pulse clock.

MIDI and the Mod Rex

The pedal's robust MIDI implementation enables you to sync devices quickly and easily as well as automate functions and changes, so they occur precisely when and where you want them whether you are working at home, in a studio or live. It accepts MIDI to enable it to tempo sync the modulation rate with an external device, to recall presets via MIDI Program Change messages, and to control any parameter on the Mod Rex via Control Change messages.

Extras

The Mod Rex lets you save and recall up to 100 presets. It comes from the factory with 20 great programs. The pedal features full stereo input and output. An external foot controller input makes banking up and down thru presets quick and easy.
