Duplicate Track not playing

Question

Duplicate Track not playing

Has this happened to anyone here? I'm using Logic Pro 8 in Logic Studio.

I create and audio track and drag in an audio loop from the loops library ... it plays fine.

Then, I create the same exact track, same parameters, and all, (by clicking on the small "+" in the inspector which says "New Track with Duplicate Setting". If I drag any (or the same exact ) audio into it, it doesn't play, doesn't light up any meters, etc.

All the parameters, volumes, etc. are the same. Nothing's muted. I tried for hours to figure it out. The I/O levels look ok. What else is there that could be affecting it?

Has anybody here ever seen that? Thanks ...

You should not duplicate the track but create a new one. Logic can assign more than one track to a single audio object but an audio object only can play one region at a time. If you mute one of the duplicated tracks, the other one will play.

Thanks Eddie,

I think I'm gonna have to dig this one out of a manual somewhere. It makes no difference what's muted or not or how the track is created. The same thing happens with Track/Create.

I think it may have to do with settings to "audio 1" or "audio 2' whatever that is. I have to get a better understanding of some of these assignment terms and output flow lines in Logic.

I appreciate you help.

Duplicating an existing arrangement track is a totally legitimate thing to do--your new track gets a new (unique) audio object with identical settings. You're clicking the "New Track with Duplicate Setting" button, right ? As long as that new track has a valid output assigned (same as your first track that works, right ?), isn't muted, etc... it should play normally.

Make sure you aren't using the "New with Same Channel Strip/Instrument" option under the track menu, though... that's totally different. That creates a new track assigned to the same audio object, so only one of those tracks can play at a time. This may be what Eddie's thinking about...

The "New with Same Channel Strip..." command is useful for compiling multiple takes/versions of a particular voice--good anytime you only want to play back one thing at a time.

If you want two tracks that play simultaneously, they need to have separate audio objects. When you look at the channel strip (mixer), right under the output assignment, there will be text like "Audio 1," "Audio 2," etc. This is different from the track name down below the fader--you can change the track name to anything you like. The text above the fader can't be renamed--it indicates the Core Audio object the track plays on. If your first track is "Audio 4," for instance, when you duplicate the track, the new one should be assigned "Audio 5," or any other number, really... the point is that it need to be a unique number... something not yet being used in your project.

Make sure your new track has a new Core Audio object... if you used the "duplicate" command, it should...

Good luck!

Thanks for going to detail,

Thats what I meant. (Usually you get a new audio object, but then you should also be able to hear the sound). You explained it in a clearer way.
