Polyend MESS Multi-Effects Step Sequencer

The Polyend MESS flips the script on what a multi-effects pedal can be. Packing four fully independent effect tracks and a powerful 16-step sequencer, it turns your effects into a performance tool. Dial in motion, randomness, and rhythm across 120+ stereo FX, from classic delays and reverbs to wild granular engines, spectral smears, and bitcrushed chaos.

Each of the four FX tracks can be sequenced separately with adjustable step length, playback speed, and chance control. That means glitchy loops on one track, evolving pitch shifts on another, and shimmering reverb tails morphing over time all synced to your tempo. Whether you're on guitar, synth, or a DAW-less rig, MESS makes dynamic, hands-on sound design second nature.

Hands-on control is at the heart of MESS. The 16 RGB sequencer pads and four FX trigger pads give you real-time access to your sequences, while the bright colour screen, push encoders, footswitches, and control pots keep you locked in. It comes loaded with 200 presets, with space for 1000 more, so you're never short on inspiration.
