Hello,
I’ve recorded a rhythm track, a second track with an electric guitar and a synth track (with Surge XT plugin). I’ve realised that the aforementioned tracks are audible in the synth track, even when muted. There’s an old forum thread from 2019 here: Previous Track "Printing" onto new track.
Sadly this solution is not working in my case, since I can’t find any possibility to turn looping off in the sound-driver settings. I’m using a Windows 11 PC with Audacity 3.75.
