Particle™ is a granular delay / pitch shifting pedal. It chops your signal into small grains and then rearranges, shifts, and mangles it, using the techniques of granular synthesis in real time. Results range from radical pitch and delay modulation to shimmering repeats to time stretching, stutter, and glitch sounds.

Five delay and three pitch modes give intuitive control over random delays, bubbling textures, cinematic soundscapes, time stretching, and rhythmic glitches. Take a unique approach beyond conventional delay, pitch, flanging, and chorus sounds. Freeze notes with adjustable threshold for stutter, punch in, or drone-line effects. Lock multiple parameters to tap tempo or MIDI sync with independent note divisions for intricate rhythms. A few quick button taps combine all of the modes for ambient textures or layered glitches.  Access hidden parameters via MIDI, tablet, or the front panel for full granular processing.

Seven pitch quantization settings allow shifting, detuning, and random jumps in octaves, octave & fifths, semitones, and other ratios.  Pitch quantization changes the behavior of randomization and detuning, adding new ambient textures.

Multiple feedback settings allow notes to be recycled, repeated based on probability and/or number of repeats, or fade out naturally.  Ping-pong feedback and random stereo panning create an expansive stereo field.

Our web-based editor gives you access to all parameters and configuration settings.  The editor allows you to name and organize presets, download them to your computer and share them on  We also provide a TouchOSC layout for expanded performance control on iOS, Android, macOS, and Windows.

The Particle 2 is performance friendly, with controls spaced for real-time tweaking and designed so you can explore new sonic territory while remaining in control. Use the assignable expression pedal or DIY-friendly remote switch for hands-free control. The Particle 2 is pedalboard-friendly with all jacks on top. With full MIDI control, stereo input/output, and +8 dBu maximum input level, it is also at home in modular setups or the studio.

Particle 2 won the Premier Guitar Premier Gear award.  Read the Premier Guitar Review (9/2019)

The Particle V1, released in 2011, was the first granular delay pedal.  The Particle 2 added stereo I/O, presets, MIDI, higher fidelity, and greatly expanded the sounds possible while keeping the lucid interface.  Learn more about the history of the Particle in our blog.
