How Do Audio Units work with XO Wave Pro?
Because Apple’s audio unit specification assumes that Audio Units will be run and viewed in the same process, Audio Units are not completely compatible with XO Wave. Specifically, the interfaces associated with Audio Units must be built from scratch using information provide by the Audio Unit. In most cases, this only causes a slight change in appearance, but the Audio Unit continues to function normally and provides you with all the controls you need in the same way as a built-in effect. Some Audio Units, however, may either provide incorrect information or require the use of a specialized interface component, such as a phase meter, which cannot be recreated by XO Wave. Such Audio Units may not be usable in XO Wave. Note that Audio Units require XO Wave Pro — they are limited to an incomplete “audition” mode in XO Wave Free.
