Polyend MESS Multi-FX Step Sequencer Pedal

Enter a new dimension of creative possibilities with the Polyend MESS, a multi-FX pedal with an innovative 16-step sequencer that lets you add generative motion to FX parameters, adjust rhythm and track length, and add randomization to the mix. With four independent FX tracks and 120 FX total, you have plenty of tools in the box, while 16 RGB sequencer pads allow for hands-on control.

What Makes MESS Different?

MESS turns effects into an instrument. Unlike conventional multi-effect units that rely on static presets, MESS offers dynamic, programmable, and performative sound design. This effect powerhouse is equally at home on pedalboards, in modular synth setups, or integrated into DAW-less setups—making it ideal for guitarists, synthesists, drum-machine enthusiasts, and sound designers.

Over 120 FX Built to Sequence or Stack

MESS features 120 high-quality, stereo effects, ranging from traditional to the experimental. Choose from analog-style modulation and time-based staples, or innovative spectralizers and new ways to use granular engines.

Multimode Reverb: 5 reverb modes with 25 submodes, from massive ambience to realistic room and plate simulations.

Granular Bust: a Dynamic multimode granular engine that transforms audio in real time.

Particle Sampler: unique granular sampling effect that captures audio from a selected step are replays it rhythmically.

Microlooping: chopping and repeating with direct control. Loop tiny fragments of sound or large subdivisions for synced micro-fragments to precise rhythmic chaos. Intuitive slicing, looping, and rhythmic manipulation from microfragments to precisely timed repeats.

Deluge of Delays: multitap, ping-pong, and single delay engines with models from tape, analog, digital, and more.

Modulation of every sort: over 25 submodes of modulation from tremolos, seasick vibratos, classic choruses, or robotic flangers.

Many Shapes: 12 unique shaper modes ranging from subtle saturation and overdrive, to aggressive bitcrushing, to sample-rate reduction.

Spectralizers: Two spectral modes for wild pre-reverberations, alien screams, or gentle harmonic smearing.

EQ, Filter, Pan, and Automate: sequence filters and panners for dynamic tonal shaping, enhanced stereo fields, and vocal formant effects.

Repitch Everything: dedicated pitch shifters and sequenced repitching for granular, spectral, and loop effects.

Make Anything Musical

MESS’s 16-step grid pad is a real-time sequencer and editor—with intuitive hands-on controlthat rewards experimentation without an advanced degree in sound design required. Sequence effect parameters, start or stop sequences without cutting out the effects, or build complex polyrhythmic patterns that evolve as you play.

Per-step parameter sequencing

Adjustable track length and playback speed for polymeter and polyrhythm creation

Chance and probability control for generative sequences or precisely times effects

Tap tempo synchronization ensures rhythmic precision for delays, tremolos, and slicers

Quickswap effects and change the effects order with the push of a button

4-Track Sequencing Power

Each track runs independently, with detailed control over parameters, time divisions, and length. Create slow spectral sweeps by slowing a sequencer down to 1/16th of the chosen tempo while increasing the speed of a microlooper for chaotic, glitchy stutters, all in the same patch. MESS has the tools to build-up textures or tear them apart.
