Greetings, I have an issue regarding a recent event I recorded w DP24sd. Through card was an approved Scan Disk 32 gb that I preformed a full format on prior to use. I recorded approximately 3 hours of a middle school orchestra competition. I initially used just an MXL condenser mic positioned high behind the conductor. I used input A to 1, 2 and 3 tracks for first 15 minutes. I then added two more Sterling mic's. One to the right, one to the left of the student orchestra aimed in their direction. Their wasn't enough time to create, load and assign for each school band, so I just monitored through headphones, and recorded the entire am line up. All appeared well with the DP24's performance. The meters were active, record was on, and the tracks we're displaying sound patterns . I asked for a little more time between bands, got permission, and 2nd half of day I loaded new SD card started loading, creating and naming separate files for each band all afternoon. I'm at my studio now reviewing results, and first SD card Audio Depot shows 7 tracks, five of which are the same size, and 6 and 7 a bit larger of data, but theirs only 13 minutes of music. I exported to view file and its still showing one song 3gb. There is however the music file shows zz files for the recordings in question. I need these wave files, can I import zz wave files into daw? What did I do wrong? The 2nd half of event with new SD card, and procedural changes came out perfect. Opinions, and options and advice would be greatly appreciated. Thanks in advance.
