RasterFX: Multi-Effects

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.
