Hi Hakan,
there was a thread on a similar topic just recently: -> http://community.vsl.co.at/forums/t/30812.aspx ... maybe one should add that MIR Pro is _so_ new that not many people will have integrated the new tool into their ongoing productions yet.
Regarding routing, there are many, many options - ranging from a whole MIR-mix on a stereo-channel, to submixes, dry and wet stems, up to individual returns of individual signals. In case you haven't done so already, please feel free to take a look in MIR Pro's manual, which contains a whole tutorial section with routing examples (p. 33 ff). -> http://dl.vsl.co.at/downloader.aspx?ID=7628
[...] Q: Is there any way to mix the completely dry signal of, for example, a vocal, with the MIR output? The wet/dry control in MIR only affects the reverberation, as far as I understand, and not the positioning and basic character.
Aehmmmm ... I'm not sure that I understood the question, sorry.
Maybe I should point out that MIR doesn't create a "reverb signal" that you you would add to a dry signal like you would in a conventional AUX-send scheme on a mixing console or in a DAW. The dry signal has to be handled by MIR too, to create a perfect match between the virtual stage positioning of the dry signal component and the actual set of impulse responses from that position.
Did this answer your question?
Kind regards,
