Walrus Audio launches Xero Polylooper dual-channel stereo looper
July 29, 2025 · 2 sources
Walrus Audio introduced the Xero Polylooper, a dual-channel stereo looper, on July 29, 20251. Guitar Pedal X reported the launch the following day and noted that the first batch had sold out2.
The pedal has two independent loop channels, each with up to three minutes of recording time and unlimited overdubs, according to Guitar Pedal X2. Gearnews describes the same capacity as "virtually infinite overdubs"1. Each channel has a volume slider, a pan knob, playback speed at 0.5x, 1x or 2x, and forward or reverse playback21. Walrus Audio powers it with its proprietary MDSP Module, and the design uses a true relay bypass that disengages the pedal when no loops are active1.
Three modes govern how the channels relate:
| Mode | Behavior |
|---|---|
| Synced | Keeps all loops time-aligned to the first recorded loop21 |
| Unsynced | Lets each channel record loops of completely independent lengths21 |
| Poly | Creates polyrhythms using shared time divisions such as 3:4 and 5:721 |
MIDI clock is supported for syncing in all modes1. The left footswitch records and plays loops, with a hold for undo; the right footswitch stops playback, with a hold for speed FX21. Double-pressing both switches toggles channel control, and a double-hold triggers full stop or full erase21. Each channel has a multicolor LED system for recording, playback and speed status21. Connections include stereo and mono in and out, an EXT switch for an external dual-stomp switch, USB-C for firmware updates, 1/8-inch MIDI In and Thru (Type A), and 9V DC at 300mA21.
Guitar Pedal X put the price at $299, with Black and White editions offered2. Gearnews lists textured beige and matte black aluminum enclosures1.
