I just finished a song and when I put it into RB3, the volume on the guitar track is ridiculously loud, and the bass and drums are almost non-existent. I checked the audio options in RB3 and both the instrument volume and the bg music volume are all the way up. The preview in magma plays the song at a normal volume too. I even adjusted the volume on the stem tracks and re-built it, but the volume is still really loud.
