As far as I can tell, Logic's default record-enable behavior allows multiple tracks to be enabled with a standard click. In order to force it into 'OR' behavior where it switches to one track at time, you have to option+click.
The problem is, more often than not I'm only recording one instrument at a time, but I have large sessions where I scroll up and down. Sometimes as I scroll or mix for awhile or take a quick break, I totally forget that elsewhere in the session I still have some other track record enabled. I've accidentally recorded over tracks this way before.
I'd much prefer to switch this behavior since multi-tracking is something I only do once in a blue moon (so opt+click = adds tracks together). But I've searched all the menus and google and I can't figure out a way. Is this possible?!
