Thank you Dietz (and Alain). Yes I did go slightly overboard with the wetness I guess, as you always do when you discover a new tool. I had to use a lot of subgroups indeed, because I have MIR24, not the full MIR (budget reasons and also an older Mac Pro, which amounts to one single reason I suppose...) So I had one position for flutes, another for oboes & english horn etc. Not ideal but the best I could manage with my current setup.
I also did some live cello & violin recordings for this film and positioned the audio channels using MIR24. It's such an easy process to get the sound you're looking for that it seems a little bit like cheating... And not a single crash after weeks of heavy editing of around 30 cues (compared to around 10 Cubase crashes per day). Great work on your side as well!
Thanks again.
