Every time I export a song out of GarageBand, the volume for the MP3 track is too low. I have to blast my volume in order to hear it. In the old GarageBand, the volume would usually be too loud on the MP3 track, but now it is the opposite. I have tried adjusting the Master Volume and the Track Volume in GB and have still had no luck. The volume problem happens when I export a track containing only Apple Loops. If the track contains music played by my keyboard, then the volume is fine.
