The way I see it, there’s 2 kinds of shortcuts, global shortcuts and context-specific shortcuts. Opening the MixConsole is a global shortcut, and quantizing the selected notes in the Key Editor is a contextual shortcut. It’d be nice if we can assign multiple contextual commands to the same key.
So, when the Key Editor is focused,
Quantize. And when the mix console is focused,
Expand: EQs or whatever you do often. When a key is assigned to a global command, the user shouldn’t be able to assign an additional command to the same key without warning of overwriting.
If this is currently possible please let me know.
