I prerecord at home using Logic pro 10. After I record all that is needed for a beat or song all tracks are exported as wave files. The Tempo information is saved then I take the files to a recording studio and have the engineer mix the files on Protools. Most of my commercially released music is mixed by Art Forrest at wall street recording studio we have been recording with him for years he is a great audio recorder find the video of us at his studio below.
