This is totally not super simple in Logic. In fact that workflow doesn't exist at all. So one thing you could do is click on your marquee selection (to split the existing region at the marquee borders), then mute the new region inside the marquee and record on another track. Another possibility: monitoring during pre-roll seems to work when you start recording anywhere before the auto-punch area, so if you place the playhead a bit - say, a quarter note - before the marquee and make sure "Play From Marquee Selection" isn't checked (long click the play button for that) it should work as well.

...or post the project itself (minus the audio files) so others here can check

I just tried with a file from this package https://github.com/ambisonictoolkit/atk-sounds/releases/tag/v1.0.0 (EDIT:seems to happen with all files in that package) and indeed I see the same issue here. So, an issue with Ambisonics files in Logic. Could you report it via Apple's feedback page?

Do you own one? In that case you could record a short file and check if the issue is reproducible with that as well.

Just installed and checked the demo version of VSM-3, definitely a (100% reproducible) bug in the plug-in. Don't chalk up all of your pains to Logic! You should contact Plugin Alliance on this topic

and all those issues should be treated in separate threads in this forum. Otherwise, confusion ensues. That looks like a bug in the plug-in itself

I can confirm this bug (happens every time if a note ends exactly at region end and the next region has the same not exactly at its start when Note Chase is on). Note Off and Note On events seem to be mixed up. You should report this to Apple via their feedback page (if not already done)

That's why I proposed sharing the audio file (or any file this is happening with). As it's reproducible for you you should also report it via Apple's feedback page The screenshot shows that both regions reference the same audio file, so, no, not a feasible workaround here

I don't even understand the issue ("a PlugIn Alliance plugin gets the honor to let the Logic automation counting the automation values"???) so maybe you can decsribe that in more detail (a separate thread would be appropriate as well for that I guess).

Can you open a separate thread for that please?

As far as I understood the OP can even reproduce this in a fresh new project, so this seems to be a different issue? The regions in the screenshot don't overlap, so the OP seems to have done that already (or used No Overlap Drag Mode in the first place)

Could you post the surround file this happens with?

Just tried this here and can't replicate that behaviour. Which Logic version are you using?

Edit->Separate MIDI Events->Separate by Note Pitch, maybe?

My first guess would be Control Surfaces as well
