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.
Expression
- 3 Control Knobs: Adjust the properties of light patterns and Cycle through modes.
- EXP/EYE Switch: Choose between manual expression or engage the Eye to add light-headed control.
- Scale Knob: Variable control of the Maximum expression value.
- Range Switch (Full/ Less/ Least): Adjusts the Maximum range of the Scale Knob.
- Tip Direction: Swaps the direction of expression between Tip-Ring and Ring-Tip for greater compatability across effects.
- TRS 1/4" Jack: Requires TRS (Tip, Ring, Sleeve) between Pedal Brain and effect.
- DC Jack: Tip Negative, Sleeve Positive.
- USB Jack: For accessing the internal Adafruit Gemma M0 platform.
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?

Cool Stuff
Arduino Inside - 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.
LED Backlit Knobs - 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.
