I recently posted a topic about sonic differences in my studio between mixes rendered in 6.5 and 7.5.30. This topic has now been moved to the lounge (probably because it had the title “Cubase 7.5.30 Sound engine”…), this was the first thing that came to my mind…
You can find it here:
in this post I did some testing, and came to the conclusion that some things ARE different (no, not the engine).
It’s the eq that is (very) different, and if my assumptions are correct something has changed for the better from 6 to 7 using groups. (better delay compensation in complex setups maybe). Anyway. To my ears my mixes sound a lot more focussed and more “hi-fi” when played back in 7.5.30.
My testing has definitely shown that there can be audible differences, and I think this post could maybe be of interest if you mix using cascaded groups or complex routing.
In short, it looks like 7.5.30 does some things better than 6.5…It certainly sounds this way overhere.
If you are not interested in compatibility from 6 to 7 just ignore this posts.
