How to see which Bus is feeding Aux?

[tsosis123]

So I am getting this message when I try to delete my Aux which I believe is some old one that doesn't have any purpose. But its saying that it is recieving signal from active Bus routing. Now I have to dig into my 70 hidden tracks and muted ones to find which one is it. Is there an easier way maybe? How to see which Bus (channel) it is feeding into this without digging into 100 tracks? Thank you.

You can see the bus number on the Input of the Aux channel.

Go ahead and delete it if you don't need the aux.

Logic reports that the bus is used because a (possibly hidden) track has a send or output routed to it. So far you knew this I suppose. Now, to see if that bus if of *real* use in your *current* version of the project, simply play the project from end to end, hit pause at the end, and see whether the peak display above the aux channel strip level meter stays blank. If so, no audio signal is actually sent to that bus (at all). Maybe it's an empty, or muted (hidden?) track that its routed to it.

 

In that case you can delete that aux channel strip anyway. Only drawback is that you cannot revert to an older state of your project later on (unmuting a hidden track for instance, since it will no longer sound the same). But alternatives (or backups) should serve for that purpose.

 

If you do have any peak level number being displayed after having pause at the end of your project, then despite your impression you do actually use that aux in your mix, so don't delete it. It might be worth investigating further exactly what uses it, especially if it doesn't seem to make sense to you.

 

PS : hitting pause at the end is only a caution safeguard. You don't want to hit stop twice which might move back the playhead (depending on your setting) to the beginning of your project as this resets to blank all peak level displays of all channel strips.
