It looks like Logic is the show stopper. I’d similar problem a year ago when I did some recordings for a customer on Logic via MADI (RME-MADIFace, MacbookPro i7, 8GBRAM, internal HDD7200, external HDD7200) and Logic. Same Hardware with ProTools (max 32ch.) and Steinberg Cubase and Reaper are working reliable. This while recording complete shows up to 3,5h+ and apr. 45ch. max.
Question is what logic version we’re talking about. I heard some rumors about logic 9 makes some trouble?
But as I’m no Logic professional I’m looking forward to some other experience statements.
