It would be great if I could select multiple songs in edit and add tag and keywords to all of the selected tracks.
Is it possible and I missing something. I tried shift and select.
Yes, that's possible. See here: https://stagetraxx.com/user-guide/songs/#edit-mode
peter When I select another song on my list to add it unchecked the previous song. I'm unable to multi select. Is there a key command I'm missing?
Are you on a Mac? Here you need to hold shift or ctrl cmd to select multiple entries.
EDIT: Corrected the key to hold.
I tried all the key combinations on my Mac and they don't work. It works great on my iOS devices. I'll use that for now. Will the keywords and tags been included in a full backup?
Yes, keywords and tags are included in a backup.
Regarding the selection: I was mistaken, it is the cmd key. Enter Edit mode, hold down cmd and select all the songs you want.
For whatever reason, cmd key and selecting multiple songs isn't working on Mac mini running Catalina OS X.
My Mac Mini is already running on Big Sur, so I can't comment on Catalina, but as far as I know there is no difference between Catalina and Big Sur regarding these key modifiers.
