My Mix Emergency will only record partial recordings now. If I try to record a full 3 hour set, only one hour will actually record. The problem is with both Apple and Wav. All m-audio midi cables won't work correctly either...I hook them up, they work for a brief period (10 Minutes) then stop working. I use a Pioneer DJM 800 as my mixer. My Laptop is a MacBook i7 with 8 gigs of Ram and a 500 gig hard drive with 200 gigs of free space on it. It runs the most up-to-date version of Lion and serato. Can you please help?
