Loop Breaker
This app transforms your audio loops into evolving compositions by introducing random modifiers and effects. It encourages creative exploration by letting you decide how to alter your sound or letting the app make choices for you.
- Gamified audio processing
- Modifier system for effects
- Probability system for modifier appearance
- MIDI CC control for probability
- Preset system for saving/recalling stacks
- Record and resample audio output
- Standalone app and AUv3 plugin

Loop Breaker is a gamified audio processing environment that periodically forces you to make choices about how your audio loops should change and how your compositions should unfold. This is primarily achieved through a modifier system; every few bars, a new modifier appears in a queue. You must decide which of your loops should be affected by the modifier. If you make no choice, Loop Breaker will decide for you. Change is the only constant. Modifiers include standard audio effects like reverb, delay, chorus, filters, granular delay, auto-pan, and tremolo. Each of these effects has multiple parameters that are set on the fly and include various onset times. Other modifiers effect loop playback: you can change the playback speed, reverse playback direction, time-stretch, re-pitch, move loop brackets via the parts system, and slice loops and then shuffle, arpeggiate, or repeat them. Modifiers stack. Within minutes, your loops will wander down their own paths and recombine to create something previously unimaginable. Loop Breaker also contains a robust probability system for controlling how likely it is that modifier types will appear in the queue and how likely it is that an individual loop will be targeted for modification, should you cede decision-making responsibilities to Loop Breaker. The probability system responds to MIDI CC messages, so you can dynamically change probability settings with MIDI controllers, automation lanes in your DAW, or via modulation sources. Loop Breaker also contains a preset system for saving and recalling modifier stacks. Take your explorations as far as you want, save a new preset, and then recall it later on, even between sessions. Like the pads and probability system, presets also can be controlled via MIDI. Still not enough exploratory madness for you? Record and resample the audio output and then re-apply it to a pad or process it further in your DAW. Loop Breaker works both as a standalone app and as a AUv3 plug-in. Loop Breaker knows that you have a hard drive full of 4-bar loops that you never turned into finished compositions. Loop Breaker wants to help. Loop Breaker wants to make sure you don't get stuck in a loop.

Make any sound move. RasterFX is a playable modular multi-effects processor for iPhone and iPad. Use it standalone with a microphone, an imported audio file or built-in signals — or load it as an AUv3 audio effect in AUM, GarageBand, Logic Pro for iPad, Loopy Pro, Cubasis and other Audio Unit hosts. BUILD YOUR EFFECT CHAIN Choose from Filter, Delay, Drive, Reverb, Grain, Repeat, Motion and Dynamics. Arrange up to six plates in series or split them into parallel A/B paths. Reorder the chain and the sound changes with it. MODULATE ANY CONTROL Patch LFOs, envelope followers, random and chaos sources, step sequencers, MIDI, macros, the XY pad or device tilt to any control. Create up to 16 modulation lines, with live arcs showing exactly how the sound is moving. PERFORM THE PATCH Morph between four snapshots on the XY pad. Turn eight macros. Hold four momentary throws for stutter, sweep, reverse and freeze. RasterFX is built to be played with one hand, not programmed and left alone. GENERATE, LOCK, EVOLVE Nudge a patch, reshape it or roll a new one. Lock the parts you want to keep, undo any result and save the seeds worth returning to. Evolve lets the patch drift over time while staying anchored to the sound you chose. SEE WHAT YOU HEAR Every effect has its own live visualizer. The CRT and halftone interface makes filters, delay taps, grains, dynamics and modulation visible without turning the screen into a wall of meters. RECORD THE RESULT Record the processed output to WAV, rename takes and share them from the app. FREE TO START. PRO ONCE. Free includes all eight effects, all modulation sources, every factory preset, three plates, four modulation lines and 60-second recordings. No ads, account, watermark or reduced audio quality. RasterFX Pro is a one-time purchase — not a subscription. It unlocks six plates, 16 modulation lines, split routing, XY snapshot morphing, Evolve, A/B compare, unlimited recording length and your own saved presets. Your saved sound always plays back exactly as created, even if it uses Pro features; Free limits editing, never playback. Made for headphones, late at night.
