A few thoughts.
first of a great topic for a varied panel to discuss.
The summing issue i think summing is an important issue. (I know that it IS the diffrence between oob and mib)*
i think adressing sevral diffrences in a specific manor. for example, instead of just saying mib gives you a darker sound then mixing oob. the way i would phrase it would be more specific to the function of summing. ie. why dose summing in the box producer a darker, (insert your favorite distinction here) sound then mixing through a traditional analog bus system.
now before everyone starts giving me grief for this post there is a fatal flaw to this question that has been brought up many times in this tread. It is that diffrent daws "sound" diffrent. (tdm vs. logic vs. nuendo. for example). not to mention that all of these daws use diffrent mathmatical formulas for the summing process. (wich is why they "sound" diffrent). And the same argument can be made for the analog summing bus used. An ssl sounds a lot different then a mackie.
another idea for a question, mabey a little of topic. What type impact dose mib have on the art of making records?
dose the flexibility of mib increase the quality of the art?
dose the loss in sound quality take away from the art?
there is obviusly a lot of factors that go into this question. i would also like to see it addressed as fairly as possible.
as far as people i would like to see on the panel (big time long shots)
Brian Transeau aka BT i think he is always pushing the limits and creativity of mib.
Simon Osbourne, Stings long time engineer. he has recently been getting closer and closer to mib from moob. i think he has some vary good insight on the topic as a whole. there are some intersting articles on him about the subject on the web. (not the one on digidesign.com it is a little skued towards PT) google it.
sorry to be so long winded and being so mr obvious on these question but its the only way i could think to say what i had on my mind. i probably should have not wrote this a 3:30 in the morning either. i hope it all makes sense. time to get some sleep got to finish mixing a session in the morning, unfortunatly its in the box.
please for give my spelling and grammer its way to late to be doing this.
*assumming playback source is the same. ie. PT bouncing to disk, pt with all channels in session routed to individual channels on a mixing board. With identicle mix settings (pans, volume) and no eq comp or anything else that might change the original sound source.
