I have been using Studio One (4, professional) for a while now and have a recurring problem. I "save" often during the recording process and always at the end of a session. Way too often, when I return to the song, one or more tracks are there but with no data (music) in them. The track is there with the name but empty. It is a real pain to try to recreate or find the missing info, and recreate the tempo changes etc. I have searched Google, the Presonus questions section, and the Presonus forum and get zero responses to this problem, so I'll try here. Anyone else have this happen or know a solution?
