I recently recorded roughly 15 songs through Presonus audiobox on to my iPad Air. At the time, the tracks were recorded as they should have been. But later I went in to listen to the tracks and had multiple issues. Several of the tracks were dead tracks. Nothing there. But when first recorded, they were fine. One track I listened to has now become 3 of the tracks, all 3 named differently, but are the same exact track. Others have just disappeared. Has anybody else dealt with this? Or had any issues?
