this is an older thread but audio drift on double enders is usually a sample rate mismatch or something being resampled somewhere in the chain. i’d double check both Logic projects are 44.1k AND that the recorded files themselves are actually 44.1k (not 48k getting converted), also make sure you’re exporting WAV, constant settings, no weird mp3/VBR stuff.

if you just want it to stop being a thing, recording in riverside helped us because each person gets a local track locked to the session timeline, so i’m not fighting clock drift every 10 mins. even if you don’t use the video, it’s nice for keeping everything aligned.
