I'm working on a piece that has 7 stereo instruments. I want to continue to work on the audio in a DAW (I'm using Sonar4 on XP). What I've been doing is sending each instrument to it's own out. So instrument 7 ends: outc ganull, ganull, ganull, ganull, ganull, ganull, ganull, ganull, ganull, ganull, ganull, ganull, a1, a1 and what I am getting is a 14 channel wave file. This is fine, when I import this into Sonar I get 16 mono files. But it would be nice if I could get to 8 stereo files more easily. For now I can export them from Sonar and create the files I need, but I was wondering if csound could make the stereo files for me, rather than the single multi-channel file.
