By educational purpose I've made a mixdown of Wagners Tannhauser overture using Kontakt. All instruments except the timpani is taken from EWQLSO Silver Edition.
I used to use the Kompact player that came with my EWQLSO SE and I've never had any trouble mixing down in Cubase SX, but now when I use the same instruments in Kontakt (1.5) I get noise occasionally? In the mp3 this can be heard for instance at 0:43 and 2:24, and more apparent at 12:11.
The mix has been slightly compressed and Waves convolution reverb is used, but those have never given me any trouble before (not that I've noticed at least).
Also, I don't know if this is an issue with Kontakt, but sometimes the volume of some instruments drop. This can be heard with the trombones for example at 2:45. When I play this section directly in Cubase it sounds ok, but not always? I'm using some MIDI cc's to control my instruments, and I get the impression that the message handling isn't 100%, or possibly leaking between VSTi instances, and that this is the cause. I've had similar problems before with other VSTi:s when I used multiple instances in SX, but those problems were never solved.
Anyway, feel free to comment on the mixdown, and if anyone has any idea what might be the cause of these problems, please help!
