I have the same song in two versions I would like to combine them without changing the performances. All the audio files are in a project with a tempo of 120 bpm throughout, they were imported from another program recorded at a different tempo, but they sound correct. The midi project has slightly different tempos virtually every measure between about 126 to 128. It also sounds correct as it was just a SMF made from the original project. When I copy and paste a midi track into the audio version, the notes are at the right measures, but are in the wrong place relative to the audio. If I try to copy the audio tracks into the midi version it is a complete mess. I guess I could probably freeze tracks from measure 1 to the end and import, but that is a tremendous waste of HD space and a redundancy. That may have been how I got all these files in the audio to start with. This keeps coming up as I transfer 30 years of projects into Logic X, so I want to know how to solve this issue. Thanks in advance.
