EFX is a 4-channel audio multi-effects processor for iPhone and iPad that’s easy and intuitive to play, yet offers plenty of depth to shape your sound and route the effects in creative ways.


Simply connect EFX to an input source: use the built-in microphone, an external keyboard or guitar (with an iOS audio interface), your favorite iOS drum machine or synthesizer via Inter-App Audio or Audiobus. You can also import your own audio files and process them through up to four effects at once.

Save your favourite settings, and then recall them whenever you want, using either the user-friendly GUI, or via MIDI program change.
