Walrus Audio Xero Polylooper Black

Revolutionize Your Looper Setup!

The Xero Polylooper is a true two-channel, bypass-looping powerhouse with independent loop control on each channel, stereo panning, variable playback speed, reverse playback, three looping modes, and intuitive operation. The Xero is your new partner for endless possibilities — creating new song ideas, practicing licks, or building ever-evolving textures on stage.

Two Loop Channels, Completely Independent Control

Xero gives you two independent loop channels — each offers:

• Looping up to 3 minutes with virtually limitless loop stacking
• Infinite overdubs
• Volume and pan controls
• Playback speed (0.5x / 1x / 2x)
• Reverse playback option

Loop each channel individually or stack them to create complex, layered compositions — all in real time.

Just Play. Simple Operation.

The Xero's two footswitches provide fast, intuitive loop control:

• Tap the left switch to record and play loops
• Hold the left switch to undo
• Tap the right switch to stop loop playback
• Hold the right switch to toggle playback speed
• Press both switches twice to switch channels
• Press and hold both switches for a full stop or full erase

These presets give you near-total control without menu diving or complicated footwork. With an optional external dual footswitch, you can take full control of both channels simultaneously — perfect for live performers and loop-centered setups.

Looping Modes for Every Workflow

Switch between three flexible loop-sync modes:

• Sync Mode - Aligns loop length to the first recorded loop
• Unsynced Mode - Loop length completely independent
• Poly Mode - Create polyrhythms with synchronized time divisions (3:4, 5:7, etc.) for interlocking textures (supports MIDI clock for precise synchronization)

Visual Feedback

Each channel has its own multicolor LED system that indicates:

• Red, green, and white for recording and playback control
• Cyan, pink, yellow, and blue LEDs show the selected playback speed
• Channel status via dedicated red LEDs

No guessing during performance — thanks to clear color assignment.

Speed FX & Direction Controls (Speed and Reverse Effects)

Flip the loop upside down or change the groove? Use the Speed FX:

• Half / Normal / Double Speed
• Reverse playback - each channel can play backwards independently
• FX activation syncs with loop start in Sync and Poly modes to ensure accurate timing

Bypass

The Xero features a true relay bypass: when no loops are active, the pedal completely disengages and leaves your tone untouched.
