Overview

A closer look at RasterFX: Multi-Effects.

RasterFX is a playable multi-effects processor for iPhone and iPad. Use it on its own with a microphone, imported audio, or built-in signals, or load it as an AUv3 effect in compatible audio hosts such as AUM, GarageBand, Logic Pro for iPad, Loopy Pro, and Cubasis. Build an effects chain from filters, delay, drive, reverb, grain, repeat, motion, and dynamics, then arrange modules in series or parallel paths. Modulation options include LFOs, envelope followers, random sources, step sequencers, MIDI, macros, an XY pad, and device tilt. The free version limits editing and recording length but lets saved sounds play back as created. RasterFX Pro is a one-time purchase that unlocks more effects and recording tools; the current price is shown in the App Store.
