I was working in Logic/Natalie on different tracks in the Synth V plug in window doing a harmony part and noticed some distortion. I bypassed the effects( to eliminate it being created by those), which helped a lot, but the effects were just amplifying the issue - I was still hearing something - so I soloed the SV tracks alone - just two of them and can still hear “beats” - phase vibration/sync type distortion. I tried creating a simple legato LaLa 3rds harmony sung slowly and it’s there for sure. I tried detuning one harmony part but it doesn’t help. I don’t want to do hard pans L/R.
Buried in a mix it’s probably not audible, but I can hear it. I can post an example - but hoping someone who does hear it can just verify I’m not crazy. lol I might be able to come up with an engineering work around on two different tracks in Logic. Maybe bouncing individual parts first could help.
