I am using Xcode and i am getting this error when trying to use with logic pro, Do you know how to get rid of this error? Thanks. This application, or a library it uses, is using the deprecated Component Manager for hosting Audio Components. This is not supported when rebuilding against the 11.00 or later SDK. Also, this makes the host incompatible with version 3 audio units. Please transition to the API’s in AudioComponent.h.
