The Walrus Audio Canvas Expression Pedal reimagines what an expression pedal can be. Far beyond a traditional single-function pedal, the Canvas Expression is a comprehensive command center for manipulating parameters across your entire setup. Whether you are sweeping delay repeats, switching presets mid-song, controlling modular synths, or automating plugin parameters inside your DAW, this pedal delivers flexible, uncompromised control.

Designed to adapt to your gear—not the other way around - the Canvas Expression removes the need to carry multiple dedicated controllers.

Key Features & Benefits

• Dual Independent Outputs: Configure Jack A and Jack B independently. Control two completely different devices simultaneously. Each output can function as:
  • A standard Expression Output
  • A Programmable Switch Output
  • A Control Voltage (CV) Output
• Universal Expression Compatibility: Say goodbye to guesswork. Built-in automatic expression wiring detection supports TRS, RTS, and TS resistance modes. Instantly fine-tune your sweep with adjustable tapers and forward/reverse sweep directions.
• Programmable Switch Control: Need to change amp channels or pedal presets? Assign either output as a momentary or latching switch, featuring customizable heel, middle, or toe activation points.
• Built for Synths & Modular Rigs: Generate control voltage (CV) directly from either output. Perfect for Eurorack systems and desktop synthesizers, with selectable voltage ranges of 0–5V or 0–3.3V.
• Deep MIDI Integration: Transform the Canvas Expression into a high-resolution 14-bit MIDI controller. Send up to 16 independently assignable Control Change (CC) or Program Change (PC) messages over both ⅛” TRS and USB-C MIDI to seamlessly control DAWs, virtual instruments, and processors.
• Intuitive Web Editor: Ditch the complicated menus. Use the powerful Canvas web app to easily configure MIDI assignments, switch behavior, TS resistance values, and global settings in seconds.
• Built for the Road: Featuring an adjustable treadle tension for a custom feel, the Canvas Expression utilizes a pot-less, string-less, and gear-less design so it won't wear out or get scratchy mid-set. Backed by a Limited Lifetime Warranty.
