Walrus Canvas Dual Expression Pedal w/ USB-C MIDI
The Walrus Audio Canvas Expression is far more than a traditional expression pedal. Designed as a flexible control hub, it features two independently configurable outputs that can function as Expression, Switch, or Control Voltage (CV) outputs, alongside comprehensive MIDI control via both TRS and USB-C. Whether you’re controlling effects pedals, guitar amplifiers, synthesizers, modular systems, or software instruments, Canvas Expression adapts to your setup with ease. Unlike conventional expression pedals that perform a single task, Canvas Expression can control multiple devices simultaneously while offering advanced customization for sweep response, switching behaviour, wiring compatibility, and MIDI messaging. Automatic expression wiring detection makes setup effortless, while onboard controls and the browser-based Canvas Editor allow you to tailor every aspect of the pedal to suit your rig. Built using Walrus Audio’s contactless sensing technology, Canvas Expression eliminates traditional wear points like potentiometers, gears, and strings for exceptionally smooth operation and long-term reliability. From compact pedalboards to complex MIDI-controlled performance systems, Canvas Expression is designed to become the command centre of your setup. • Dual independent outputs configurable as Expression, Switch or CV • Control two separate devices simultaneously • Universal expression pedal compatibility • Automatic TRS, RTS and TS wiring detection • Supports TRS voltage divider and TS resistance expression modes • Adjustable expression taper • Forward or reverse sweep direction • Programmable switch outputs • Momentary or latching switch operation • Heel, middle or toe activation point • Multiple switching configurations • Forward or reverse switch triggering • Control Voltage (CV) output • Selectable 0–3.3V or 0–5V CV ranges • Ideal for Eurorack and modular synthesizers • Advanced MIDI controller functionality • Up to 16 assignable MIDI messages • MIDI Control Change (CC) support • MIDI Program Change (PC) support • Independent TRS MIDI and USB MIDI outputs • High-resolution 14-bit USB MIDI • MIDI input for remotely enabling or disabling outputs • Browser-based Canvas Web Editor for advanced configuration • Configure MIDI assignments, switch modes, resistance values and global settings • Firmware updates via USB-C • Adjustable treadle resistance • Contactless sensor design with no pots, gears or strings • Backed by Walrus Audio Limited Lifetime Warranty Specifications • Outputs: Two independently configurable TRS outputs (Expression, Switch or CV) • TRS Expression: 50kΩ voltage divider • TS Resistance Mode: Selectable 10kΩ, 25kΩ or 50kΩ • Switch Output: Tip-to-Sleeve, Ring-to-Sleeve or Tip & Ring-to-Sleeve grounding • Control Voltage: Selectable 0–3.3V or 0–5V • MIDI: 1/8” TRS Type A MIDI In & Out • USB-C: MIDI In/Out and firmware updates • Power: 9V DC centre-negative, isolated supply, 300mA minimum • Dimensions: 48 × 91 × 225mm (H × W × D) • Weight: 1kg (2.2 lbs)
