Pedal Brainz | Left Brain Version 1

Left Brainz

The Left Brain is a light-controlled expression pedal that interfaces with effects offering expression control.


Controllable patterns of light result in the virtual turning of knobs when used in-conjunction with the available properties of a compatible effect pedal.


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?


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?


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.

Software

Pedal Brainz GitHub

A programmable Arduino device with an on-board RGB LED can be accessed via USB to load new patterns or to write your own using widely available LED flashing tutorials and resources.

Mode Advance:All potentiometers to fully counter clockwise (left) for 1 second then rotate potentiometer A2 clockwise (right) for Mode Change.


Startup Mode:The last Mode Used before powering down will be Saved as the Startup Mode.

Modez

The Left Brain will include 10 Modez at Launch and features a user programmable Arduino that can be updated over Micro USB.

3 knobs are available to control properties of light patterns which are then transformed to provide expression control for most effect pedals.

See Modez and Modez Descriptionz Below

Suggested Instructions

Inital Settings:

1. Tip Direction: TR
2. Range: Full
3. EXP | EYE: EXP

4. 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

Modez

Modez 1 | Squarez

Squarez Mode alternates between two colors of flashing light with control over the brightness of each color and the speed between each blink.

This mode is great for setting a repeating pattern between two values that can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Speed between 2 Blinks

A1 = Blink 1 Color Value (Brightness)

A2 = Blink 2 Color Value (Brightness)


Modez 2 | Trianglez

Trianglez Mode provides smooth variable speed ramping between the minimum and maximum values set by the Left Brain hardware and adds the ability to sustain the duration of the minimum and maximum value individually.

This mode is great for simple ramping modulation that can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Fade speed of LED

A1 = Duration when LED is fully on (It's Lit)

A2 = Duration when LED is fully off (It's Dark)

Modez 3 | Trianglez Random

Trianglez Random Mode carries forward the ramping and duration from Trianglez Mode and brings randomization to each of the properties. This mode adds variation to the speed of ramping and duration of light/ dark while randomizing these properties in-conjunction with the values set by the Left Brain hardware.

This mode is great for randomized ramping modulation, bringing upredictibility that can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Amount of Random Time Added to A1, A2

A1 = Duration when LED is fully on (It's Lit)

A2 = Duration when LED is fully off (It's Dark)

Modez 4 | Rainbowz

Rainbowz Mode is just the coolest way to modulate by adding subtle variation through color cycling the visual spectrum. A simple sinewave-like pulsing of variable speed rainbow colors with control over the duration when dark between cycles and the maximum brightness working with the values set by the Left Brain hardware.

This mode is A Huge Ever Growing Pulsating Brain That Rules from the Centre of the Ultraworld and can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Rainbow Cycle Speed

A1 = Maximum Brightness

A2 = Duration when LED is fully off (It's Dark)

Modez 5 | Rainbowz Random

Rainbowz Radom Mode adds random brightness variation to the coolest way to modulate the visual spectrum of colors. A simple sinewave-like pulsing of variable speed rainbow with control over the Randomization of maximum brightness for each cycle and control over the duration when dark between cycles.

This mode adds wild variation within random constraints and can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Rainbow Cycle Speed

A1 = Amount of Randomized Maximum Brightness

A2 = Duration when LED is fully off (It's Dark)

Modez 6 | Mountainz Random Repeat

Mountainz Repeat Mode is the expression of forever climbing, ascending and descending modulating mountains within constrained randomization.

This mode starts with a sine wave that repeats with the ability to dial-in just the right amount of randomness. Controllable speed is infatigable while climbing up and down the waveform, but where this gets interesting is control over the chance to randomly stop and have a snack during the cycle...essentially pausing the waveform and sustaining the expression value for a random duration.

Great for repeatable ramping with the added ability to add some wiggle to the waveform and a chance to sustain values that can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Cycle Speed

A1 = Amount of Randomness

A2 = Amount of Snacking/ Random Duration of Snackz

Modez 7 | Mountainz Random Random

Mountainz Randon Mode builds on the functionality of Mountain Repeat Mode by randomizing the random waveform after each cycle. This generates a new random mountain of expression values that can be constrained to a simple sinewave or unhinged in everflowing randomness.

With the ability to control the speed of the ascent and descent if these mountains of expression, the influence of an effects parameters adds variability. The snack chance value increases the possibility that waveform cycle will pause and sustain the expression value for a random duration.

This mode is brings never-ending waveform mountain ranges of expression to surprise and delight during a sound journey. Mountainz Random Mode brings a tireless cycle of constrained randomness that can be fine-tuned according to the effect it's used with and the properties of the effect.

A0 = Cycle Speed

A1 = Amount of Randomness

A2 = Amount of Snacking/ Random Duration of Snackz

Modez 8 | Strange Attractorz Single

The Strange Attractorz Modez leverage the power of maths to create wandering waveforms of controllable chaos. The modulation produced by the Lorentz attractor creates 3 independent waveforms whose values combine in brightness with controllable speed, maximum brightness, and amount of waveform randomness via the 3 control knobs.

The 3 Strange Attractorz Modez: Singlez, Doublez, and Tripelz leverage the increasingly unique unpredictability of the maths to create patterns of light that bring complex and surprising variations to drive the expression.

These modez bring the wild-card, water-rippling, wow & flutter of unpredictability to any effect with expression control. Varying degrees of unhinged modulation can be refined between subtle undulations over long durations and high-velocity warping of properties.

A0 = Cycle Speed

A1 = Maximum Brightness

A2 = Amount of Randomness
