I've used Logic express 8 now for about 8 months. I record and mix 1 minute spots for radio broadcast. Recently, I've run into a problem where the vocal I mix on site (not in the studio) drops out. I record with an RE 20, an RE 50, API Pres directly to a Sony DCM 50@24/96. I process the voices, bounce to 24/44.1 and mix with a canned music CD @ 16/44.1. When the voices are bounced to 24/44.1, they sound perfect. They're all strong, and even, my ears and the meters don't lie. But the second bounce (down to 16/44.1) after adding canned background music results in the voice recorded on site dropping out, I mean really dropping out -15 to -20 db. I have no clue as to why, and wondered if this is a problem with Logic express 8. Previously I recorded these vocals with a Sennheiser MKH 60 at 16/44.1 with no problems at mix down whatsoever. I have a suspicion that the bounce algorithm is causing this. If you have any suggestions please let me know. I want to record at 24/96 as it is noticeably higher definition on the transcients even after a bounce down to 16/44.1.
