Are you asking for doing a stereo mastering without playing and
recording the song? I wonder if this is needed. Anyway, I'm not sure if
I do understand what exactly you are asking for by the word 'rendering'.
Is the host Qtractor? And do DSSI plugs what you want? I guess 'we' do
misunderstand what you're asking for, by your first email.
