    The Polyend MESS is a pedal that opens up a new world of possibilities. MESS blends traditional sound shaping with generative and performance power with four independent effect tracks can be freely assigned to over 120 studio-quality effects, all with sequenceable control over multiple parameters. Start a sequence and create entirely new textures that evolve in time — from lush ambient washes to glitchy chaos. Or switch off the sequencer and use MESS as a powerful, traditional multi-effects pedal.

     

    MESS combines a powerful multi-track step sequencer with effects brimming with Polyend character – from classic modulation, delay or reverb to experimental effects never before seen in pedal form. With four fully customizable effect tracks, craft ambient soundcapes, intricate glitch sequences or even a familiar four effect chain – all moving in sync.

     

    Polyend Mess Multi Effect Step Sequencer Features

    • Adjustable track length and playback speed for polymeter and polyrhythm creation
    • Chance and probability control for generative sequences or precise timing 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
    • 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
    • 4-Track Step Sequencer – Direct sequenceable control of all four effects tracks. Control each effect individually with per-step parameter changes.
    • Over 120 different effects - Each track can be freely assigned to any of the 120+ effects.
    • Per-Step Parameter Sequencer – Customize each effect track’s parameters with per-step control.
    • Deep Customization Options: Adjust per-track speed and length. Add step probability, randomized playback, polyrhythms, and polymeters.
    • MIDI Compatibility – Sync clock to make MESS the ideal drum machine companion or integrate into a pedalboard. Use CCs to change mix and track parameters.
    • Expression Pedal Control - choose from multiple destinations to assign to the expression pedal.
    • 1000 Presets - Save up to 1000 presets on the device and easily scroll presets with stomp switches or MIDI PC messages to change from over 100 presets.

     

    4 Effect Tracks

    Combine four effects for every preset to create your own unique multi-effect. No limits are placed on what effect each track contains. Run a reverb into a delay or a spectralizer into two bitcrushers and create vibrant tones, suitable for any instrument.

     

    125 Stereo Effects

    Want a specralized micro-looping effect with randomized repeats? A time-shifting chorus into a reverb that slowly gets darker over time or simply a traditional modulation, delay, and Reverb chain? With over 120 effects to assign to the four tracks, MESS opens the door to the unexpected.

     

    Why Sequence?

    MESS has the sequencer power expected from a Polyend instrument. Control per-track speed and length to create polyrhythmic or polymetric sequences or use chance options to easily create complex generative effects that never sound the same twice. Instantly add movement and musicality to any effect. Reverbs bloom, delays evolve rhythmically, and modulations shift in sync with your tempo.

     

    Extravagant or Traditional

    MESS excels at in-your-face weirdness while still covering all your pedalboard basics. Use it as an avant-garde idea generator or a straightforward pedalboard replacement, no sequencing required. Tap the play switch to kick the sequencer into motion and shift from a traditional FX chain to an evolving sequence.

     

    Reverbs & Delays

    MESS features a extensive range of stereo reverb and delay modes. Explore lush ambient spaces, tight room simulations, and modulated plates with 7 core reverb types and dozens of sub-modes. Delay options span everything from warm analog and LoFi modes to clean digital repeats. Single, multi-tap and ping-pong modes create rhythmic posibilites from subtle echoes to chaotic trails. Stack and sequence them to shape depth, space, and movement in completely new ways.

     

    Granular & Glitch

    9 versatile modes for Granular and Glitcher engines break apart, blur or fragment any signal. The granular sampler runs sound from the selected sequencer step for tightly synced granulation or infinite washes. The Glitcher engine transforms the input signal in real time into a scattered field of microsounds for instant manipulation and experimentation. Stack granular engines for massive textures, pitch shifting or unreal soundscapes.

     

    Shapers, Drives & Filters

    Shape your sound with subtle saturation to natural overdrives to complete destruction with bitcrushing and sample rate reduction. Add EQs and Filters for polish and a finalized sound. Engage the sequencer and hear the shapes transform.

     

    Pitch Shift & Spectralize

    Make anything musical with a wide range of pitch shifting options. Spectral engines warp, pitch shift and transform a large spectrum of sound. Or chose dedicated pitch-shifters with monophonic pitch tracking to re-harmonize your sound or sequence complete musical compositions from a single note.

     

    Slicers & Microloopers

    A collection of repeater algorithms can be tightly sequenced for microlooping, repitching, arpeggiation, or even tape-stop style effects. With per-step chance controls, MESS can generate randomized loops, stutters, and repeats unlike any pedal before— for spontaneous experimentation or controlled chaos.

     

    Everything changes

    MESS changes how you think about effects. With all the effects designed around sequencing multiple parameters, discover something new with every sequence. Dynamic effects evolve and transform to bring life to create more than your standard repetitive effects. With built-in chance and probability controls, MESS can generate randomized glitches, stutters, and repeats unlike any pedal before. MESS is a rhythmic effects processor that fits in any setup from a pedalboard to a DAW-less setup — a transformative effect for guitar, drum machines, synths and sound designers.

     

    Drone and Dissolve

    MESS is a texture box with all effects stack-able in any combination to create intricate, layered sound for deep sound design without even starting the sequencer. Effects are activated with the on stompswitch, even withtout the sequencer running – with the exception of a few sequencer reliant effects. Sculpt the signal with twelve shaper modes and 7 EQ and filters options to create realistic recreations of analog overdrives, bit crushing and redux video game sounds, or crushing fuzz tone.

     

    Shape and texturize

    MESS is built for adventurers in sound design. Blend pitch-shifted reverbs with spectral bursts, sliced loops with endless tape echoes, or granular fragments with analog-inspired drifting delays. Create vibrant, evolving sounds that aren’t possible with other devices. Dial down tempos—as slow as 1/16th your tapped tempo—and let your sound drift, blur, and dissolve at any speed.

     

    Make Anything Musical

    MESS’s 16-step grid pad is a real-time sequencer and editor, with intuitive hands-on control that 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.

     

    MESS turns effects into an instrument. Unlike conventional multi-effects units that rely on static presets, MESS offers dynamic, programmable, and performative sound design. This effects 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.
