Just a quick try of throwing it on every track in a session, I have roughly set up a session enough to distinguish something, and put MPX on every track, with basic settings except flutter to 0 (so, using it without the side effects such as wow flutter and noise). Here's the result, there may be a few trigger errors in the beginning :
clean :

clean with tape on master track only :

tape :

tape with -3dB :
http://dl.dropbox.com/u/881054/shootout waves mpx/ashes_mpx_-3dB.mp3
in both mpx ones, the master track instance is set to roughly hit -3dB on the meter (the effect is more dramatic there so I'm not changing it)
Keep in mind the volume is affected and I didn't match the RMS volume of all tracks.
EDIT : I'm adding the "clean with just mpx on master track"
The difference is tremendous and too much, but I think it's in the good direction. May be better to just use it on busses. I'm considering putting this on every viable track with a ligh input setting, and maybe printing it if it sounds good and safe in the end.
BTW, is it me or does it make the reverb on the snare more defined, or easier to hear ?
