Hi @motreg,
Can I expect cubasis 3 to load synth app data etc.?
Basically “YES”, but it often depends on 3rd party plug-ins (instruments/effects) in use and the chosen format (Audio Unit, Inter-App Audio), if these do load properly.
Apple introduced Audio Unit support many years ago, which provides much greater options and clearly can be seen as their successor to Inter-App Audio. Therefore, we strongly suggest using AU plug-ins where possible.
Below please find our dedicated articles, with additional infos about AU and IAA.
Limitations of Inter-App Audio
In regards to Inter-App Audio, it makes sense to first launch the stand alone app versions of the plug-ins in use, before launching Cubasis and the project using these plug-ins.
In addition, if 3rd party plug-ins fail to load within a project, simply shut down and restart Cubasis which often helps too.
Stay well,
Lars
