creates a greater distinction between the
responsibilities of mixing and mastering engineers
when using the multitrack as the source to the
mastering application.
I guess this could work as long as all parties understand the
demarcation. I can imagine resistance from mastering engineers who
might regard a multitrack project as 'unfinished', or not want to
take responsibility for the mix.
On the other hand, I'd love to be able this kind of flexibility, but
it would depend on having Ardour or something compatible with our
multitrack project files at every stage in the chain.
