Thanks for the kind words! I'm just glad if I get enough things right to help somebody every so often.
I like your snapshot approach; good digi-mixers like these allow for a lot of file handling flexibility. It really gets down to how you work and what your challenges are (clients, archival work, remixes, etc etc).
Funny thing: I just discovered a new (to me) usefulness for TMC. I'm in process of mastering an EP at the moment, and am trying to nail my song-to-song RMS consistency a little more quickly. So for grins, I load up TMC's Meter Window along with my stereo editor and its mastering plugs. However, I set the TMC's meters to 'AVERAGE.'
Then, I run my file, making level, eq and compression adjustments - watching the DM's meter bridge channels (set at 'peak,') and the TMC's meters which show RMS (average). After the file is rendered, I go into my file 'trays' and audition various portions of the completed files, paying close attention to the TMC RMS/averages among the tunes displayed in a separate window beneath my editor's. (I also do 'stat/analysis' for actual numeric feedback, showing specific RMS, average high, low, peaks, etc).
This had been the best workflow discovery I've made in a year.
