Posting now in 2014 on Version 7…
Has this not been fixed? Still having the same problem as the poster from 2011.
When you flatten a time warped file with MPEX, it loses several dB of amplitude.
What makes this frustrating is that some of the events on the same track cannot be bounced with MPEX, they can only be bounced with “Realtime,” (a lesser algo I assume.) So what you get is a playback where the track output volume jumps up and down by several dB, depending on what algo you could use on each event when flattening.
So your options are:
Forget MPEX and use the “Realtime” algo with flatten on all the clips, even if audio quality is not as good, to maintain consistent playback volume in the track, or
Run a test to find out exactly how much MPEX is reducing the amplitude, then tediously gain up every event flattened with MPEX by an equal amount.
What would be really wonderful is to fix these old problems in the software before starting to add any new features or plugins- so that the tools we have to work with are rock solid, before adding to them.
