I have two (master) sources that I would like to do a "matrix mix" of and I'm having an issue with getting the recording to line up. Both sources were recorded by me, so it's from the exact same location, however I recorded one in 24-Bit/44.1 and the other in 24-Bit/48. Could this be causing me an issue? I've done this several times before and have had zero issues, but this one show is causing me fits. Any best practices out there?
