How can I see the old side pane view rather than the one shown in the attached screenshot?
Mouse click on the word library again then eventually click the tabs to the left if need be:
Click on the File menu item and it will take you to the side list view especially if you selected the Classic view.
Sorry, but I don't understand it (see attached screenshot).
It is in front of your eyes actually, in your first screenshot… 🙄
Sorry, but I can't see the "Classic View" or am I blind?
It's in your first screenshot!
anyway… just click the LIBRARY tab (at least in Full version this works.. in Player version, i don't know)
It does not work rather in the standalone version nor in mein DAW (Logic Pro).
