What cases are thee when you need to select none?
I can't say I've personally really noticed a lack of it much while editing
notes, though I totally understand it if the OP needs it. I suppose I have just naturally just clicked into open space to deselect all without really thinking about it. In some ways perhaps thinking of it as "Select None", the OPs words, not yours, is a slightly misleading description as indeed normally you'd want at least one thing selected.
So with that in mind, the one area that I have found occurs enough to be regularly frustrating is selecting
all sequencer tracks, such as for copy/pasting between songs. It's very hard to deselect them all, because the standard deselection options any normal PC users would attempt first—because that that's how every other app they've used for thirty years works!—nowhere was marked in the GUI to click out of it to reselect just one track.
You can click a track to rearm it for recording etc, but all the tracks are
still "selected" in terms of dragging and, here's the one that's caught me out more than once, Ctrl-D duplication of that drum track I thought I'd selected, where suddenly your computer has frozen for five minutes while it attempts to duplicate 30 tracks
Click a sequencer clip? The clip will open as normal, but nope, all tracks themselves are still selected.
Click anywhere in the track info on the left. Nope.
You'll see there's an extra dark bit on the far left that indicates a track is selected? Does clicking even that reselect just that track? Nope.
Double-click the track? Nope. Still all are selected.
Create a new note lane? Nope. You've got a new note lane in the currently armed track, but all tracks themselves are still selected.
Try it now: Open a song with a load of tracks, Ctrl-A, and then try and deselect the bastards. Then just for lols click one track and then Ctrl-D it.
The only way to deselect all—afaik—is to create a new actual track (r-click, create audio track etc).
So the quickest way is probably Ctrl-T (which frankly I had to look up just now, as I tend to create devices from right-click or browser), and "Create Audio Track" seems a pretty obscure choice as the inverse of "Select All", and with the added benefit of always results in something extra you didn't want will have to need to delete.
Anywhere you have Select All, you need a Deselect All: that wasn't brain surgery, that's basic GUI usability. The lack of it is the selection equilavent to including the Copy but not Paste. Windows apps at least do tend be a very erratic here in choice of shortcut: Photoshop I know uses Ctrl-D, while MS Excel uses ESC and MS Word is... fairly obtuse (arrow keys, but normally most I guess would just mouseclick whitespace).
