3 recording levels which one is right?

Yes, that should work, provided the PRO version.
Sort of off topic, I must correct “Performer signals are additionally beeing recorded on the Performer Computer, those are directly from the input and not influenced by the VST Connect plugin “RECORD” section.” The fx button does however burn inserts into the HD files, so you could have a dry and another wet channel from the same input for reamping. Just wanted to clarify.
