Walrus Audio Xero Polylooper - Cream

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

Two Loop Channels, Fully Independent Control

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

You can loop on each channel individually or stack them together to build complex, layered compositions—all in real time.

Play Naturally. Control Effortlessly.

The Xero's dual stomp switches keep loop control fast and intuitive:

•Tap the left stomp switch to record and playback loops

•Hold the left stomp to undo

•Tap the right stomp switch to stop loop playback

•Hold the right stomp for speed FX

•Double-press both switches to toggle channel control

•Double-hold to trigger full stop or full erase

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.

Looping Modes Built for Any Workflow

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)Visual Feedback That Keeps You Locked In

Each channel has its own multicolor LED system showing:

•Red, Green, and White for recording and playback controls

•Cyan, Pink, Yellow, and Blue LEDs for different speed effects

•Channel Control Status via dedicated red LEDs

Instantly know what's happening—no guesswork needed, even mid-performance.

Speed FX & Direction Controls

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

Bypass That Listens

The Xero features true relay bypass—when no loops are active, the pedal automatically

disengages, keeping your tone completely untouched.
