I am upgrading my live show backing tracks to play from a Denon DN -F350 rack mount mp3/mp4 player using a flash drive. I'm using tracks created in Band In A Box 2013 and Logic Pro X. I save all tracks from BIAB as mp4a tracks to my desktop, and then drag those tracks into LPX. I do some editing, including levels. The problem is that some of the tracks from BIAB are too low compared to the other tracks, and even though I raise their levels in LPX, when they are then saved into iTunes, their volumes are then lowered back to orig levels. I do not have any limiting or compression on the tracks. No matter what I do in an attempt to raise their levels in LPX, they end up in iTunes back at the original levels. I A/B the output levels of the tracks in LPX and iTunes and they are distinctly different.
Suggestions?
TIA
