Rainbow Machine

The Rainbow Machine by EarthQuaker Devices is a polyphonic pitch-shifter pedal that offers a wide range of features and functionality. Here are the technical specifications and details:

- The pedal utilizes modern DSP to create real-time pitch shifting using digital oscillators.
- It features controls for Pitch, Primary function, Tracking, Tone, Secondary function, and Magic regeneration control.
- The Pitch control adjusts the frequency of the polyphonic pitch-warped harmony from a fourth below the input to a third above, and every atonal pitch in-between. It can also be controlled via expression pedal.
- The Primary function control adjusts the volume of the polyphonic harmony.
- The Tracking control adjusts the lag time between the wet and dry signals.
- The Tone control rolls off some treble for a darker, "vintage" sound.
- The Secondary function control adds an octave of the Primary harmony, and when the Pitch control is set to noon, it adds an additional chorus voice for modulated, triple-tracked tones.
- The Magic control is a regeneration control that creates aliasing and other effects by feeding the Primary and Secondary signals back on themselves and each other.
- The pedal also features silent flexiswitch footswitches on both the Activate and Magic functions, allowing for versatile and expressive control.

These technical specifications and features make the Rainbow Machine a versatile and powerful tool for creating a wide range of pitch-shifting and modulation effects.
