Avid have announced Pro Tools Sketch, a new music creation component in Pro Tools® which will be available as part of the forthcoming 2023.9 update this September. It’s a non-linear, clip-based editor, and will be a new window in Pro Tools, as well as an iPad app. It appears to have similar functionality to something like GarageBand’s Live Loops.
