Koala FX

Koala FX is the ultimate creative effects auv3 audio unit for iOS. It offers 16 one-touch effects that you can play intuitively like an instrument, allowing you to effortlessly morph and twist your track into something beautiful.

It includes all your favourite mix effects from Koala Sampler, but refined and souped up to allow super smooth cuts and crossfades.

Apply effects to your whole mix just to add some lofi warmth or to liven things up… or use it to sculpt synth sounds to blend in with the rest.

  • Save up to 8 scenes per preset, so you can cut between them in time with the music
  • Smoothly crossfade between scenes with a giant 8-way X-Y pad.
  • Rearrange the order of the effects by dragging them.
  • A togglable hold mode allows you to keep some effects engaged, and others off when you let go of them.
  • Fully automatable via your host (effects, volume, scene, XY pad)
  • UI is fully resizable, works great in any aspect ratio
