Left Brain - Expression Modulator
The Left Brain is a light-controlled expression pedal that interfaces with effects offering expression control.
Over 50 Modez of controllable expression, an expression pattern loop recorder, and a host of other features to harness the potential waiting in your effects pedals.
50 Modez are accessible across 5 Banks featuring an incredible selection of favorites as well as many which have been specially formulated to add unique expression and constrained randomness. Greatest Hitz: Shapez: Rainbowz: Naturez: Attractorz: Each Mode comes with a unique set of controls that allow for the fine tuning of modulation. Special focus has been put on creating Modez that are both functional and creative, often bringing the ability to refine or extend randomization to reign in the wild oscillations when called for or let loose with suprose and delight. Here are some additional features that make the Pedal Brainz Left Brain unique: External Brightness Control: Light Loopz - Expression Looper Mode: Duration/ Speed Multiplier:
What if you could get a little more modulation from an effect on the floor, without resorting to yet another giant-sized foot-controllable expression pedal.
Tired of repeating patterns of sine/ square/ triangle waves and eager to break the cycle with some constrained randomness?

Scale Rotate Fully Clockwise for Toe Down Rotate Fully Counter-Clockwise for Heel Down Adjustments EXP is for full manual expression control EYE adds light-dependent expression control If Scale does not express effect fully, try adjusting the Range switch
If there is no expression change when manually adjusting Scale (EXP), try changing Tip Direction
Have you ever wished for a tiny semi-sentient clone of your brain to turn the knobs of effect pedals while floating effortlessly across the fretboard without worry?
Do you like watching patterns of flashing light working in concert with the parameterization of effect properties while jumping off the deep-end of reality?
Harness the fully configurable power of your Left Brain and unlock the creative expression waiting for you with Pedal Brainz!

Modulation Waveforms
While each mode is unique in this Bank, they cover the basics represented across the other Banks and are the perfect place to begin exploring Expression Modulation.
A collection of Modez that fall into the Square and Triangle shaped modulations category, with a few surprises.
Undulating color sequences with various static and random variations that can be modified.
The great outdoors represented though color patterns, spontaneous eruptionz, and wild abandon.
Based on the Strange Attractors branch of mathematics, these modez provide creative, and often, non-repeating and steadily evolving patterns.Modulation Controlz
This Mode sets the Maximum Brightness for the External Controls. If the external lights are too bright, you can turn them down using this Mode without effecting the Expression values.
Light Loopz allows for the Recording of a combination of Manual Fade and/ or Momentary Full Brightness that plays back with adjustable Speed and Brightness.
This Mode sets a Multiplier Amount that can be used to extend/ slow the duration of the cycling x1, x2, or x3.Left Brain - Creative Expression
Cool Stuff
An Arduino QTPY is the Brainz of the operation offering creative computer controlled modulation with open-source software and full programmability. With some coding, the Left Brain can be adopted and expanded to allow for any controllable patterns of light you can imagine.
Addressable LEDs behind each knob provide visual feedback for modulation patterns with light. 5 LEDS (2 internal, 3 external) can be programmed to modulate the expression or provide illumination through the knobs.More Cool Stuff
Two buttons make changing between Modez and Banks of Modez easy. This also allows for the ability to leverage utility and special Modez for advanced configuration and Light Loopz Mode.
Each of the models in the Pedal Brainz Series ia daptable to ensure maximum compatibility across the specifications of different effect pedals. This is achieved through a matrix of resistors that can be switched between (10k, 25k, 100k) in-conjunction with the scale knob, bringing flexibility and creativity.
