I am putting together a bunch of beats for my second release, which will be a compilation album. It is hard enough for me to find a dope vocalist to match the track, but I know I gotta handle my end first and foremost, which is producing the heat. Question is, when I ship these tracks out for mastering, are my best wav files the way to go, or do I give the studio my Reason files to be mastered track by track? Any help from your experience is appreciated...
