I was orchestrating a piece with 40 different instruments going on at once, and i noticed that the system was voice robbing and it would randomly take out certain instruments at certain times because it couldnt handle it all. Is there a recommended limit in Logic that one should use regarding the number of software instruments that should be used at once? I also was adding surround software instruments with non surround instruments and it seemed like this caused a problem as well. Is it recommended to not do this? For example, the surround brass, or cinema brass seemed to take up a lot of space.
