Yeah I did do it - just did describe it. I bounced a number of MP3's of the project --- one normalized and one not.
I put both the normalized and non-normalized MP3's into separate, empty Logic Projects, used the same interface and headphones to listen.
The normalized version sounds like the Original (the one I want) through the interface, the non-normalized version does not, it sounds like the MAC version (the one I got after initially bouncing it, it having been modified heavily).
