Take Command of Your Effects - The Walrus Audio Canvas Expression Pedal in Gray

Canvas Expression reimagines what an expression pedal can be: two independently configurable outputs capable of Expression, Switch, or Control Voltage, plus deep MIDI control over products via ⅛” TRS output and USB-C. Canvas Expression isn’t just another expression pedal. It’s a command center for manipulating parameters that adapts to nearly any pedalboard, synth, or desktop setup.

Whether you're sweeping delay repeats, switching presets mid-song, controlling modular synths, or automating plugin parameters inside your DAW, Canvas Expression gives you flexible control without compromise. Configure every output exactly how your rig demands and save yourself from carrying multiple dedicated controllers. Traditional expression pedals do one job. Canvas Expression was designed to do nearly all of them.

Dual Independent Outputs

Each of its two independent outputs can function as a standard expression output, a programmable switch output, or a control voltage (CV) source, allowing a single pedal to control multiple devices across nearly any setup. Whether you're connecting to pedals, amplifiers, synthesizers, modular systems, or your computer, Canvas Expression adapts to the gear you're using instead of forcing your rig to work around it.

Customize Your Way

Built-in automatic expression wiring detection removes the guesswork of compatibility, while adjustable tapers, sweep direction, switching thresholds, and output behavior let you fine-tune exactly how your expression signals respond to the movement of the treadle.
