Glitch 2 is a multi-effect sequencer that routes incoming audio through up to eleven effect modules — Retrigger, Reverser, Stretcher, Shuffler, Tape Stop, Lofi, Modulator, Gater, Delay, Distortion, and Randomizer — arranged in a drag-and-drop pattern editor. Each program holds 128 scenes, each independently sequenced and triggerable from a MIDI note. The sequencer runs from 1 to 8 beats at 2 to 8 divisions per beat. Multiple effect lanes play simultaneously. Released free in memory of its creator, Kieran Foster (1979–2026).

Key Takeaway

Glitch 2 defined a workflow that the entire glitch-effect category still follows: a sequencer-first layout where effects are blocks drawn into lanes, not signal-chain inserts applied globally. The interface is fixed-size and cannot be resized. At free, that tradeoff costs nothing to accept.

Glitch 2’s core mechanism is a multi-lane sequencer. Effects don’t process the signal continuously — you draw blocks into lanes and the plugin activates each module only during the steps those blocks occupy. Retrigger, Shuffler, Reverser, and the rest all run simultaneously if their blocks overlap.

Where lanes are empty, the dry signal passes through. That’s the layout the glitch-effect genre eventually standardized around, and Glitch 2 is where it originated.

The plugin ships with 128 scenes per program. Each scene has its own independent sequencer pattern, timing, and effect state, triggerable from any of the 128 standard MIDI notes. Scene-switching mid-arrangement is the intended workflow: one scene runs during the verse, a different pattern fires on the chorus, a third drops in for the breakdown — each a completely distinct block arrangement using the same effects.

Sequencer Layout and Pattern Editing

The sequencer operates at 1 to 8 beats with 2 to 8 divisions per beat. At 4 divisions, each step is a sixteenth note; at 3 divisions, each step is an eighth-note triplet. Beats and divisions are per-scene settings, so a two-beat 4-division pattern can exist in the same program alongside an eight-beat 3-division scene without affecting either.

Drawing a block into a lane activates that module for the duration of the block. Blocks can be resized by dragging their edges, split with a middle-click, and erased by right-clicking. The effect processing order is set by dragging module names in the arranger column — stacking Distortion before Reverser produces a different result than the reverse order; that order is a program-level property, shared across all scenes.

Effect Modules

Retrigger captures a slice of the incoming audio and loops it at a rate that can slide from an initial speed to a final speed over a defined transition time — the bouncing-ball deceleration effect is a direct product of that parameter triplet. Reverser captures audio between two user-defined points within a buffer and ping-pongs playback between them, so the loop boundaries can isolate a hit tail while leaving the attack untouched.

Shuffler records a buffer and plays back randomized slices with independent probability controls for Shuffle, Repeat, and Reverse — three separate chance parameters that each fire independently per slice. Stretcher applies granular time-stretching with grain size, jitter, and an envelope follower that modulates grain size against the amplitude of the incoming signal. Lofi runs bit depth reduction in signed or unsigned mode — unsigned skips the DC bias and produces a harder-clipping result at low bit depths.

Scene Control and Randomization

Glitch operates in one of three trigger modes: Host (transport-synced), Gate (MIDI note held), or Latch (MIDI note fires, scene runs until stopped). Gate and Latch modes apply per program, not per scene. The Quantize setting delays incoming MIDI notes to the next beat subdivision, useful when triggering from a live controller and needing scene changes to land on the grid rather than wherever the key was pressed.

Randomize and Mutate operate at four levels independently: the full scene, the effect state only, the sequencer pattern only, and individual effect modules. Mutate adjusts by small amounts rather than replacing entirely — useful for generating variations of a working pattern without losing the overall structure. The Randomizer module controls the weighted likelihood of each effect appearing when the sequencer auto-generates a pattern; setting a module’s weight to zero excludes it from all random generation.

Gater, Delay, and Per-Module Controls

The Gater is a trance-gate module with its own embedded 16-step sequencer running inside the main sequencer’s pattern. Step time and Smoothing control the sharpness of volume transitions between steps — low Smoothing produces hard cuts, high Smoothing produces slow fades between volume levels. The Delay module is tempo-synced with a Slew control that governs how quickly the delay line catches up to a new time setting; at low Slew, a time change produces a pitch-warping dub effect during the transition.

Every module except the Randomizer shares common filter controls — low-pass, high-pass, band-pass, and band-stop — plus per-module Mix, Pan, and Volume. The master output has its own Mix (fully dry to fully wet), Pan, and Volume controls at the program level. These master controls apply across all scenes in a program.

Pros & Cons

Pros:

• 128 independently sequenced scenes per program, each triggerable from a MIDI note — arrangement variation lives in the scene bank, not in the DAW timeline
• Mutate and Randomize operate at four separate levels, so pattern generation stays targeted rather than wholesale
• Effect processing order is drag-and-drop per program, making module stacking order a first-class composition parameter

Cons:

• The interface cannot be resized; on high-DPI displays the fixed layout requires OS-level or DAW-level scaling to remain readable
• The Stretcher’s granular engine produces noticeable artifacts at short grain sizes — that character is part of the effect, but it limits usefulness in contexts where clean time-stretching is needed

Editor’s Note: Glitch 2 went free in version 2.1.5 following the death of Kieran Foster in July 2026. The version number itself is “in memoriam.” For anyone who used it while it was paid, the interface is exactly as it was. For everyone who hasn’t — this is where the sequencer-first glitch workflow originated, before it became the layout everyone else adopted.
