As far as I know this has been a known issue throughout the last couple of versions of Logic Pro. Has anyone found a way around this nightmare problem? For those that don't know what I'm talking about; sometimes, when creating a new track Logic decides to make it a Solo Lock track. ie if you solo something else from the mixer Solo Lock tracks will play regardless unless you actually mute the Solo Lock tracks. You can tell the difference between a normal track and a Solo Lock track because in the channel strip the solo button is red. There is no logic (no pun intended) as to when Logic decides to dump some of these annoying f***ers into your arrangement. Often, if you create 10 new audio tracks, 3 may be Solo Locked, or maybe 2, or maybe none at all. Control clicking on the red solo button does temporarily take off the solo lock but you can guarantee, a few minutes later, it has reverted back to it's Solo Lock status. I really cannot believe that Apple have not sorted this out yet. It's certainly been there since Logic 8 and is a known issue. Or at least the amount of posts thrown up by a Google search a year ago and even now, suggest that. Come on Apple get your finger out and sort this out!! Logic Pro? I'm starting to wonder what the 'Pro' actually stands for!
