MIDI Library Folders
macOS only lets an app reach folders you have pointed it at. So that PXR can find the files that sit alongside your music, you tell it where your MIDI library lives, once, and it keeps that access from then on.
Why it helps#
Many MIDI files rely on companion files kept in the same folder:
- Cover art images shown in File Info and on the now-playing display.
- MT-32 setup files (
.syxor.mtx) that a piece needs before it plays (see MT-32 Support). - Unique SoundFonts tied to a particular file (see Unique SoundFont).
When you open a single track directly, macOS does not normally grant access to its neighbours, so those extras can go missing. Adding the folder to your library lets PXR load them automatically.
Adding a folder#
In Settings → General, under MIDI Library Folders:
- Click Add Folder and choose the root of your MIDI collection. PXR keeps access to it, and everything inside it, across launches.
- Remove takes a folder back out of the list.
It is enough to add your top-level library folder; PXR reaches everything beneath it.
Note
Once a folder is in your library, importing a playlist whose tracks live inside it no longer asks you to grant access. PXR already has permission, so the import just goes ahead.

If a folder cannot be reached#
If a saved folder lives on a network share or an external drive that is offline, PXR cannot reach it at launch and will tell you, naming the folder. You can Retry once it is back online, Skip for Now, or Remove from List if you no longer need it.
