Rainbow Machine

Hey buddy, welcome to your new Rainbow Machine! The Rainbow

Machine is a polyphonic harmonizing modulation machine. It takes

modern DSP and uses it as a tool of future past to create real time

pitch shifting using digital oscillators. The sound is much different

than most modern day pitch shifting devices. It was imagineered to

be wild and out of control and slightly imperfect while still tracking up

and down the guitar neck without glitching out. A cold digital beast

made to pretend it has feelings. It will do basic polyphonic harmonies

from a 4th down through a 3rd up and every atonal pitch in between.

You may add in an accompanying octave to the harmony by bringing

up the Secondary function control. You can take it way beyond and

open up your third eye by bringing in the Magic. The Magic is the

heart of the Rainbow Machine. In conjunction with the Tracking

control, the Magic creates wild pitch take offs and descend’s, chaos

chorusing, shrieks, pixie trails, groans, gurgles, briggles, bruggles,

bridals and other general mayhem. An amazemerizing machine

of wizard blessed wizardry. A device of signal transformation and

imminent destruction. Totally not for purists and/or tone hounds.

The Rainbow Machine is true bypass with an all analog dry signal

path. It is made by hand in a basement in Akron, Ohio.

Controls

Pitch- This controls the pitch of the harmony. All the way counter

clockwise is a 4th down, all the way clock wise is a 3rd up. The

middle position is unison. The pitch can be controlled by an expression

pedal as well.

Exp- This is an expression pedal control jack for the pitch. The

Pitch control is defeated when an expression pedal is inserted.

Primary- This controls the volume of the Primary pitch shifted signal.

Unity is about 2 O’clock, anything above will boost the signal.

Secondary- This controls the volume of the secondary pitch shifted

signal. The Secondary signal is one octave above the Primary from

noon up and one octave below from noon back. Unity is about 2

O’clock, anything above will boost the signal.

Tracking- This controls the amount of lag time between the direct

dry signal and the shifted wet signal. The pitch shifted signal will

track right on the dry signal when this control is all the way clock-

wise. It will start to lag behind the more it is reduced. This function

is especially useful when the “Magic” is engaged.

Magic- This adjusts the “weirdness” of the effect. The end result is a

wide variety of wild effects depending on where the other controls are

set. The magic control will only work if the magic switch is engaged

and the primary and/or secondary are in use. (Technically, it’s

a regeneration control that creates aliasing between a mix of the

primary and secondary functions feeding back against each other.)

Tone- All the way clockwise is full signal, reduce to soften the highs.

Switches

Activate- This is the bypass switch.

Magic- This turns the magic on or off. It is a jolt to the system so

a “pop” will be fairly common. The sound is not as obvious when

engaging the magic while playing. It can be reduced by clicking the

switch on and off a few times prior to use.

Power

The Rainbow Machine does not use batteries. It requires an industry

standard negative center, 2.1mm barrel, regulated 9v power supply.
