Earthquaker Devices Rainbow Machine™ Version 2 Polyphonic Pitch Mesmerizer

Welcome to the Rainbow Machineª, in all its synthetic glory! This one is for experimenters, adventurists, and noisemakers. Totally not for purists and/or tone hounds. There are no natural sounds that come from this box. It takes modern DSP and uses it as a tool of future past to create real-time pitch shifting using digital oscillators.

Stop? Okay, fine, but what if I told you the Rainbow Machine has been completely re-imagineered from the pixie dust-covered ground up to be more versatile, twice as loud as the original, with an extended delay time, deeper chorus tones, silent Flexi-Switchª foot switches on both the Activate and Magic functions, and most of all, has more Magic?

The Rainbow Machine is built around a DSP pitch warping engine thatÕs designed to be slightly imperfect; colored with digital remnants of the cosmic dust we've picked up across the multiverse. That is to say it's a cold digital beast made to pretend it has feelings.

The Pitch control adjusts the frequency of the polyphonic pitch-warped harmony from a fourth below your input, to a third above, and every atonal pitch in-between. Noon is the unison position. Use the Primary function control to adjust the volume of the polyphonic harmony.

You may add in an accompanying octave or thicken the modulation by bringing up the Secondary function control. The Tracking control adjusts the lag time between the wet and dry signals, and the Tone control rolls off some treble for a darker, vintage sound. Clockwise is bright, counterclockwise is dark.

Features:

• Measures 4.65" x 3.65" x 2.25" with knobs
• Power: The Rainbow Machine should be powered by a standard 9-volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. Do not run at higher voltages!
• Current Draw: 60mA
• Input impedance: 1M
• Output impedance: <1K
