Compatible with AUv3 host apps such as GarageBand, Auria, AUM, Cubasis and n-Track Pro.

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. Twin 3 will appear in the list of Audio Unit extensions for instrument plug-ins in the host app.

Another FabFilter classic. If you hear a sound in your head, this synth can bring it to reality.

One of the benefits of the Auria Pro DAW app early on in iOS music production was the IAP FabFilter apps that were available in the Auria store for purchase. But included with each Auria purchase was the FabFilter Twin 2 synth. When FabFilter released their plugins on the App Store in AUv3 format the Twin 2 synth wasn’t included. Now the waiting is over with Twin 3. It’s everything that made Twin 2 so special and then some. The gorgeous user interface is pure FabFilter, everything is laid out logically and is easy to operate. You can modulate modulations man, it’s deeep. Don’t sleep on Twin 3, this is a serious electronic musical instrument.

First Impression

I haven’t been inspired by a synth in a long time. Thank you, Fab Filter, for showing me it’s still possible for me to love an app.

Beautiful and strange, with one omission

This is a this is an amazing synthesizer. The depth of modulation and unlimited potential for sound design make this a must have. With that said, I find that there is one glaring omission - headphone output. In spite of the fact that the app is installed on my lesson 30 day old, iPad Air and connected to my AirPods Max the app does not route audio to the headphones. Yes, audio streams from the iPad to the AirPods on other applications. Please fix this so I can give you the fit star.
