• When you mix your beats, have these on a-3db output especially if these will undergo mastering after because this gives provision on headroom and preserves the dynamic range of your music. The final track will sound thin and weak without dynamic range; thus, make the track as loud as possible without over compressing. This way the mastering engineer can run the track through their expert compressors and gear.
• Lastly, you should have a backup of the master copies of your original track in your hard drive. The record company may own the sequence but the individual beats are still yours.
