Alexander Colour Theory Step Sequencer

The Colour Theory.  Each step in its sequence is a new pathway to adventure, each new colour is part of a palette of mystery.  Every moment brings a new surprise, as the patterns cycle and interact.

The Colour Theory combines a versatile eight-step sequencer with a powerful effects processor, creating rhythmic combinations seldom heard outside of a rack of synths.  It’s small but mighty, utilizing our Neo Series technology in a completely new way.

What is a Step Sequencer?

Imagine a drum machine that plays different sounds on each beat - kick, snare, kick, snare.  Now replace those drum sounds with pedal settings, and you’re getting close.

The Colour Theory allows you to preset different values for its effects - each step of the sequence may be set to any values you like, so as the sequence plays the effect changes automatically.  You can set the Colour Theory to play a series of tones in OSC mode, or to open and close a filter in FLT mode.  The only limit is your own imagination.

Neo Series:

The sonic scientists at Alexander Pedals have been working overtime to cram the most pedal into the smallest box, and we now present the Neo Series!  Each Neo Series pedal incorporates an advanced 32-bit microcontroller adding presets, expression, and MIDI capability.

The Neo Series pedals are small but mighty!  Imagine having a single pedal on your board that can access up to 4 separate preset tones with a touch of your toe.  Connect an expression pedal to "morph" between two distinct settings for each preset for dynamic real-time effects.  Or connect the Neo Footswitch to enable your choice of preset select, tap tempo, or start / stop the sequence in real time.

Select Button - tap to choose a new effect mode:

PIT - Sequenced pitch shifter.  This effect can create harmonies or pitch shifts, with any interval from 1 octave down to 1 octave up.  The pitch and tone of the effect signal may both be sequenced.

MOD - Sequenced digital time modulation.  The delay time ranges from 0 milliseconds to 300 milliseconds, and both the delay time and feedback may be sequenced.  Try the delay effect with two steps and a high lag to create a very lush chorus or vibrato.

FLT - Sequenced resonant filter.  This is a low-pass filter that can have high levels of resonance, to the point of oscillation.  Be careful, this thing can get wild at extreme settings.  Filter frequency and resonance may both be sequenced.

TRM - Sequenced tremolo.  Create rhythmic patterns or insane stutter modulation with this one.  The tremolo rate and waveshape may both be sequenced.

OSC - Sequenced synth oscillator.  This is useful for making melodies or whacked-out siren sounds.  The pitch range is a couple of octaves, and even "in-between" notes outside the normal tempered scale are available.  Value controls the pitch and Tweak blends between sine and square wave shapes.  We promise your neighbors will hate this mode.

PWM - Synthesized octave effect.  Don't know why we thought this would be cool, but here you go.  This mode turns your guitar signal into a monophonic digital square wave, with the divider rate set by Value.  This will get DOWN, to subharmonic levels.  It's kind of nuts.  The Tweak knob controls a modulation effect on the synth wave.  Try this for making your neighbors hate you even more than OSC mode.

Power Supply:

The Colour Theory requires a 9V DC power supply with a 2.1mm pin, center negative, 80mA.  The Colour Theory is not designed to be powered on supplies higher than 9V and does not use a battery.  The Colour Theory should work fine on a multi-pedal "daisy chain" connector, but if you encounter excessive noise or hum try a separate power supply.
