Ok. One reminder: I think it's safe to say, that MIR won't be availible in the next half year. So I don't think you're doing anyone anything good with wanting specific answers to specific questions that may even change until they developers know what the final product will look like. There are many ideas behind this, and some will make it, and some will not for various reasons. That may also be the reason they are not so responsive every next minute you ask, Christian. Take a deep breath, and just enjoy what they're telling you beforehead [[[;)]]] There's still enough time in the 4 weeks between announcement and release to discuss details, hehe [[[;)]]] Otherwise - perhaps VSL staff could make you a sticky MIR thread [[[;)]]]
So far I understood the MIR concept the following way:
You keep your current slaves, you keep your current DAW. You add a powerful additional machine for MIR. you connect your DAW to your slaves, the slaves to the MIR machine, and the MIR machine is your final output (that can be connected back to your DAW also). Some numbers mentioned 4 up to 64 slaves that could be connected (I guess technical limits will be the factor here). I'm sure that when it's called "offline" bouncing that you can bounce multiple tracks at once, coming from all the different slaves.
I'd not even wonder if they'd implement a FXTeleport like engine that is sending the audiotracks via Gigabit network to the MIR machine, as it would make perfect sense to me. Handling different audio streams from various slaves would be quite an easy task then. Only thing that has to be taken into account somehow, that offline bouncing may take longer than online rendering from the slaves - well, buffer the data that comes in, voila.
Once the different tracks are availible in the MIR machine all the magic is happening that Dietz so often described: mixing, balancing and reverbaration are no longer processes seperated from each other, but all controlled via one interface, with the possibility for presets and automation. A multitude of parameters are dealt with here: Position, elevation, stereo width, directivity, filtering, volume (both of the dry and the "wet" signal), and "some less self-explaining parameters" that Dietz wouldn't let out for us.
So once the offline thing is done you got one or maybe multiple audio files for further editing - would make sense for postproduction - that is if MIR will support multi output.
So that's my point of view on this. A user's point of view just reading quite a lot around in the last days (man why do you guys post sooo much in a month where I'm absent).
Hope this helps,
