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 1/8” 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.
MIDI Control
Beyond analog control, Canvas Expression becomes a powerful MIDI controller capable of sending up to 16 independently assignable MIDI messages over both USB-C and TRS MIDI. Using the Canvas Expression web editor at https://canvasexp.walrusaudio.io, assign control to pedals, processors, DAWs, virtual instruments, and plugins with smooth, high-resolution parameter sweeps or instant preset changes.
With customizable treadle tension, onboard configuration, and an intuitive web editor for advanced setup, Canvas Expression is designed to become the central control point for virtually any modern rig.
