Walrus Audio Xero Polylooper Looper

Dual-Channel Creative Looper

The Walrus Audio Xero Polylooper is a uniquely designed dual-channel looper that empowers you to create, layer, and explore new musical ideas with ease. Built for performers and studio creatives alike, the Xero offers up to three minutes of record time per loop, unlimited overdubs, and full control over volume, panning, playback speed, and reverse looping—all without the need to scroll through menus or deep-dive into settings.

At the heart of the Xero are two fully independent loop channels that can operate in three distinct modes. Sync Mode keeps both loops perfectly in time, ideal for traditional looping workflows. Unsynced Mode frees each channel to have its own timing and loop length, opening the door to ambient textures and evolving soundscapes. Polyrhythmic Mode lets you create complex rhythmic interactions by locking each loop to a shared pulse while allowing them to run at different lengths.

Smart stomp gestures put real-time control at your feet. Tap to record or play, hold to undo, and double-press to switch between channels. You can link both channels together for rich stereo looping, or use them separately for more experimental layering. Multi-color LEDs give you immediate visual feedback, and if you want expanded control, the Xero supports an external dual footswitch for hands-free access to both channels.

The Xero is equipped with stereo inputs and outputs, MIDI IN and THRU over 1/8" TRS, and a USB-C port for future firmware updates. It’s also designed with true relay bypass, so your tone stays completely unaffected when the pedal isn’t looping.

The Xero Polylooper is compact, intuitive, and built to inspire—whether you're rehearsing riffs, composing ambient arrangements, or performing live.
