Since its first release in 2005, FabFilter Twin has been famous for its filter quality and oscillator sound. FabFilter Twin 3 expands and improves on its predecessors in every area, including a complete redesign of the GUI and workflow, more and better oscillators and filters, a radically powered-up modulation system, an all-new FX section, and much more. Sonically versatile, supremely intuitive, and spectacularly ‘analog’, Twin 3 is a dream instrument for creating synth sounds of all kinds, from basses, leads, and pads to plucks, drums, effects, and beyond. The Twin 3 app lets you play via the on-screen keyboard or a MIDI keyboard connected to your iPad. To use Twin 3 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis.
