FabFilter has announced that all FabFilter Pro plug-ins are now available as AUv3 plug-ins on iOS, so they can be used in any AUv3-compatible host.
With this release, all FabFilter Pro plug-ins are available to use in any DAW on the iPad that supports AUv3 plug-ins. Compatible hosts include Auria, GarageBand, Cubasis, AUM, and n-Track Pro.
The AUv3 plug-ins are available for sale individually, or as a Pro Bundle that includes all of them.
This is fantastic! This makes the iPad a viable mastering platform!
