Were the relative levels on v1 correct? I mean, did you go over every track and set a new max. volume or turned up everything the same amount.
For example cd1 main title vs. cd2 imp. march, the imp. march should get a little more volume than the former, or??

It must be difficult to set the relative track volume for a set with so many edits as this, some tracks probably have/should have much lower volume because they weren't played as loud as others.

ABC, I'd really like to know a bit about what kind of software/hardware you use for this, editors or plugins or whatever.. Do you work with mastering professionally or are you just insanely talented? ;)
