I’m of the same opinion. I wish Cubasis’ internal sounds were of a higher quality so as not to have to leave the program at all. However, between IAA and Audiobus 2, I do prefer Audiobus, mainly because of state saving. I don’t really record audio and really only use Cubasis as a sketchpad when I"m away from my DAW.
I would be curious what sort of workflow other’s are using.
