Pro Tools Export/Import

I've tracked a lot of sessions in Pro Tools studios and edited in SONAR. Rather than messing with OMF, I just took the raw WAV files, brought them into SONAR, and did all the editing/mixing in SONAR. That way I didn't need the OMF parameters showing pan etc.
 
I'm not interested in transferring parameters between applications, only files, so I can use the unique attributes of the target program. If you transfer right after tracking (capture), then all you really need is broadcast WAV files.

I've done multiple complex orchestral sessions (with different sections, layering, etc adding up to over 140 tracks in some cases) recorded in both Pro Tools and Nuendo, and done both OMF as well as simply importing broadcast wavs depending on the situation.
 
Some best-practices for mass-importing wavs in SONAR:
- Make sure your recording DAW is set to timestamp the wavs when tracking. That way when importing to SONAR you can have them automatically spot to the right place even if it doesn't start at origin. You may need to set your SONAR project so origin is 1:00:00:00 in SMPTE instead of 0:00:00:00 so it doesn't import 1 hour into the session.
 
- When dealing with multiple takes of multitrack recordings, it's a good idea to import one take, do some basic volume/panning/etc., put all the tracks in a folder, then save as a track template. That way whenever you want to import the same setup in e.g. a different project, or even the same one assuming doubling layers or whatever, you can just create another instance via loading that track template, then "Import Audio" on the first track in the folder and grab additional takes.
 
- When browsing hundreds of audio files created in the original DAW's audio folder, remember that sorting by "Date Modified" will almost always give you a very neat way to browse individual takes of a multitrack session. Also within each individual take, both Pro Tools and Nuendo will create/modify the files in a multitrack in a certain order, which is then reflected in the "Date Modified" sorting in explorer, which makes your life easy when importing considering the above bullet point about track templates. With a good (handwritten or otherwise) take sheet with actual real-life timestamps (e.g. time of day, not place in session) it makes finding the exact take you want to import extremely fast.
 
- If for whatever reason timestamped importing fails to put the clips in the right place, a good fallback is, if tracking to a concrete tempo map, to always start a recording on a downbeat of a certain measure, which is then noted in the take sheet. Turn off all DAW features that may mess with this (e.g. anything that pre-records, like punch-in for Pro Tools, or the pre-roll in Nuendo, since both can shift the start point of the recorded audio data from the intended downbeat)
