Do audio engineers typically go on a split sheet?
When it comes to splits, with regard to whoever is doing mixing and mastering, if it's not your producer, typically they do not go on the split sheet. They do not necessarily have owner stake on a song. They usually are paid a fee as a service to mix and master your song.
