Release Notes Maintenance Update 1.6 - There was a problem when rendering offline with specific hosts, reported by users, that has been fixed now. Background: (Many host developers continuously try to teach audio unit developers. Now we want to teach these host developers. ^^) It is highly problematic, if hosts do a separate process for 'freezing' and exporting audio with (new instances of) audio units invoked. Some hosts even do allow to select completely different global parameters (sample rates and block sizes) for such actions. This is conceptually a bad idea, as this may lead to different rendering results and is also highly problematic for the invoked audio units, because there may be static resources and dependencies between multiple running instances and other stuff happening at runtime. A host should actually do the down rendering of the audio stream exactly the same way as it does the realtime rendering to prevent theses potentially problems. If resampling and/or format conversion are required, this should be done afterwards by the host. Only this way consistent results can be expected by the users. 'What you hear is what you get' is a logical paradigm here. If it works realtime, it should work with freezing and exporting and : exactly the same way and result.
