There’s a limitation, in place right now, regarding saving patches and including the aux and bus routings. Logic’s own default patches have this functionality but the end user is restricted in this area.
One workaround is to pack everything into a summing Track Stack but this is not always so elegant and includes unnecessary routings.

Here’s an alternative method:

1. Create an audio or software instrument channel strip and create one or many bus routings to use with your favorite effects.

2. Create tracks for the aux channel strips and make a summing stack of them. The easiest way to do this is to select the tracks you want to bundle then from the mixers’s local menu choose Create Track Stack for Selected Channel Strips or assign your own key command. A small drop-down window appears asking you to select the kind of stack you want. Choose Summing Stack.

3. Open the MIDI environment and locate the original channel strip. Drag and drop it over the Sum track then delete the redundant duplicate track inside the stack…

I get many questions on how to move Logic’s Apple Loops and samples to an alternative location like i.e. to a secondary internal or external drive.
There’s widespread information about using aliases when linking back to Logic Pro X’s default locations. Unfortunately this is a very risky assumption because every update related to that content will overwrite the alias and recreate an ordinary folder instead. The problem is that your other content will be orphaned and you will end up with library content that needs to be redownloaded again.

The correct way of do this is to use symbolic links.

Symbolic links, or symlinks, are part of the underlying file system…
