Rainbow Machine Polyphonic Pitch Mesmerizer

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 flexiswitch footswitches on both the Activate (1) and Magic (2) functions, and most of all, more Magic.

The Rainbow Machine is built around a DSP pitch warping engine that’s 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 (3) 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. Pitch may also be controlled via expression pedal. Use the Primary (4) function control to adjust the volume of the polyphonic harmony.

[Pro Tip: With the Pitch control set to noon, the Rainbow Machine acts as a chorus. Use the Primary control to adjust the wet signal volume and select the delay time with the Tracking control. The tracking improves as this control is increased, so turn it up for tighter tracking with a shorter delay time or turn it down for longer delays and more ambience.]

The Tracking (5) control adjusts the lag time between the wet and dry signals. Tone (6) rolls off some treble for a darker, “vintage” sound. Clockwise Tone settings are bright, counterclockwise is dark.

The Secondary (7) control adds an octave of the Primary harmony. When the Pitch control is above noon, Secondary adds an octave above the harmony. When the Pitch control is below noon, the Secondary control will add one octave below the harmony. With the Pitch set to noon, the Secondary control adds an additional chorus voice for modulated, triple-tracked tones. Use this control to blend in faux-shimmer sounds or a low-frequency rumble. It’s up to you. From there, it’s only a matter of how weird you wanna get.
