1.9.9 iSem and Viking AU performance

[LSlowak]

@fotizimo

So something I have just been finding, and do not know if I should post a new topic, is when I open a project that has a few AU’s, Cubasis takes some time to open the individual AU’s, but when I go to play them, there is no audio. The CPU still spikes as I mentioned before, but Cubasis doesn’t play any audio from the AU. I see the transport indicator move along, and I see the midi notes in each lane, but there is no audio from the AU’s.

Has anyone else noticed this type of behaviour before? At this point, I basically can’t use iSem, or Viking Synth for more than one instrument.

Hi fotizimo,

Please double check that the AU instruments in the project are properly loaded, by opening their interfaces in the AU instrument rack.

In some cases, AU instruments fail to load and need to be manually re-loaded by tapping the corresponding button in the AU instrument rack or re-loading the project.

Please also have a look at the limitations of Audio Unit extensions we’ve released in the topic back with the 1.9.8 release:

Hope that helps,
