I just finished a new song and haven't found the answer to a problem. The mix sounds great during most of the song. All the instruments and vocals are "sitting" in their tracks well. All are clear and well defined until the last chorus. It just falls apart. It sounds like a mess. The over all sound is not clear. There is a loss of definition. The only track added was a lead guitar doing fills. I don't know if it's over compressed, under compressed or what. The VU's are not pegging. I am using reverb at different levels by buss on all the tracks. I have tried different compression settings and no compression. Do I start the mix at the last chorus and hope the rest sounds right? Any suggestions would be greatly appreciated. Thanks!
