With the latest version of logic, 10.6.1, on Catalina, I'm encountering strange behavior that I don't recall seeing before: when I try to play back a track that is record-enabled, mute, pan, and fader functions do not work. In other words, if a-record enabled track track is playing, muting, changing pan or changing volume have no effect. Conversely if I start playing a track that is record-enabled and muted, when I unmute the track nothing happens. However all this changes if the green Software Monitoring button in the top Control area is enabled. Then a record-enabled track plays back as expected, with all channel functionality working properly.
Is this a logic quirk that I never noticed, or a bug with the new version, or just a bug on my system?
