Key Features

  • Dual configurable outputs
  • Expression, MIDI, switch and CV control in one pedal
  • Contactless magnetic sensor for smooth, reliable operation
  • Web editor makes advanced setup quick and intuitive

Walrus Audio Canvas Expression Pedal Overview

The Walrus Audio Canvas Expression Pedal goes far beyond the role of a traditional expression pedal, giving you flexible control over pedals, amplifiers, synthesisers, modular rigs, and DAW setups. Two independently configurable outputs can each operate as expression, switch, or control voltage outputs, allowing you to control multiple devices simultaneously without adding extra controllers. Dedicated TRS and USB-C MIDI outputs expand its capabilities even further, making it easy to automate parameters, switch presets, or integrate seamlessly into modern MIDI-based rigs.


Built around a contactless magnetic position sensor, the Canvas Expression delivers exceptionally smooth, accurate performance without gears, cables, or potentiometers that can wear over time. Automatic cable detection supports TRS, RTS, and TS configurations for quick setup, while adjustable tapers, response direction, switching behaviour, and pedal resistance let you tailor the feel to your playing style. Advanced settings are easily managed through the intuitive Canvas web editor, making the Canvas Expression a powerful command centre for virtually any performance or recording setup.

Flexible control for any rig

The Canvas Expression is designed to replace multiple dedicated controllers with one highly adaptable pedal. Each of its two analogue outputs can be configured independently as an expression output, programmable switch, or control voltage output, allowing you to control different devices at the same time. Whether you're adjusting delay repeats, switching amplifier channels, controlling synth parameters, or automating software in your DAW, the Canvas Expression adapts to the way you work. This flexibility makes it equally at home on a compact pedalboard, a modular synthesiser setup, or a fully integrated studio environment.

Powerful MIDI integration

Beyond analogue control, the Canvas Expression functions as a capable MIDI controller with dedicated TRS MIDI and USB-C MIDI outputs. Each MIDI output supports up to 16 assignable Control Change and Program Change messages, giving you detailed command over compatible pedals, processors, virtual instruments, and recording software. High-resolution 14-bit USB MIDI delivers exceptionally smooth parameter changes, while independent MIDI routing makes it easy to control hardware and software simultaneously. It provides professional-level MIDI functionality without the complexity normally associated with programmable controllers.

Smooth performance without compromise

Instead of relying on traditional gears or potentiometers that can wear, stretch, or become inconsistent over time, the Canvas Expression uses a contactless magnetic position sensor for exceptionally smooth and reliable operation. The pedal's resistance is fully adjustable, allowing you to fine-tune the feel to suit your playing style, whether you prefer a lighter action for fast sweeps or a firmer response for precise control. Automatic cable detection recognises TRS, RTS, and TS wiring configurations, making setup fast and removing compatibility guesswork.

Simple programming and customisation

Configuration is straightforward thanks to the pedal's intuitive onboard interface and the powerful Canvas web editor. Advanced options including output assignments, MIDI mapping, switch behaviour, control voltage settings, taper curves, response direction, global settings, and firmware updates can all be managed quickly without navigating complicated menus. This combination of immediate onboard access and deeper browser-based editing makes the Canvas Expression equally approachable for first-time users and experienced players building sophisticated performance systems.
