Convolution reverb in Rooms! is now free
The price of the Convolution Reverb in-app purchase in https://apps.apple.com/app/id572894725 has dropped to 0. This includes using the reverb via Audiobus or IAA. The plan for the upcoming version 7.0 of the app is to introduce a new in-app purchase which makes the convolution engine available via AUv3.
