Walrus Audio Xero Polylooper

Walrus Audio Xero Polylooper is a true bypass, dual-channel looping powerhouse with independent loop control on each channel.

The pedal has stereo panning, variable playback speed, reverse playback, three looping modes, and intuitive stomp gestures. The Xero is your new partner for perpetually endless ways to create new song ideas, practice your licks, or build endless textures on stage.

You can loop on each channel individually or stack them together to build complex, layered compositions—all in real time.
Xero gives you two independent loop channels—each with its own:
• Loop up to 3 minutes with near infinite stacking of loops
• Unlimited overdubs
• Volume and Pan controls
• Playback speed (0.5x / 1x / 2x)
• Reverse playback option

With built-in gestures, you stay in control without menu-diving or complex tap dances. Need even more control? Plug in an external dual-stomp switch to simultaneously take full command of both channels—perfect for live performers and loop-centric setups.

Switch between three flexible loop sync modes:
• Sync Mode – Keeps all loops time-aligned to the first recorded loop
• Unsynced Mode – Let each channel record loops of completely independent lengths
• Poly Mode – Create polyrhythms using shared time divisions (3:4, 5:7, etc.) for interlocking textures
(Supports MIDI clock for precision syncing)

Want to flip your loop upside down or twist it in time? Activate Speed FX to unlock:
• Half / Normal / Double speed
• Reverse playback – Each channel’s playback behavior can be manipulated independently, letting you remix on the fly.
• FX activation syncs to loop start in Sync and Poly modes, ensuring accurate timing

The Xero features true relay bypass—when no loops are active, the pedal automatically disengages, keeping your tone completely untouched. This pedal is powered by a standard 9 volt power supply (not included) and draws 300mA current.
