Walrus Audio Xero Polylooper Stereo / Dual Looper Pedal, Black - Secondhand

Full Description

Dual-channel looping with full control

Each channel on the Xero Polylooper operates independently, giving you complete creative freedom. With up to three minutes of recording time per loop and unlimited overdubs, you can build evolving soundscapes or intricate rhythmic patterns on the fly. Volume, pan, speed, and direction can all be adjusted separately, allowing for true stereo layering and detailed mix control.

Three flexible loop modes

Switch between Sync, Unsynced, and Poly modes to suit your approach. Sync keeps all loops time-aligned, Unsynced lets you explore loops of different lengths, and Poly opens the door to interlocking polyrhythms. From ambient textures to structured compositions, the Xero adapts easily to your looping needs.

Speed FX and reverse playback

Transform your loops in real time using the Speed FX function. You can slow down, double, or reverse playback independently on each channel, with changes syncing precisely to the start of the loop in Sync and Poly modes. This lets you remix or deconstruct your performance with tight timing and creative impact.

Streamlined performance control

Dual footswitches and gesture-based controls put powerful looping functionality at your feet. Tap, hold, or double-tap to access core features like record, undo, erase, and speed FX without diving into menus. You can also add an external dual footswitch for even more control, making the Xero perfect for live performances.
