The latest update brings another round of bug fixes and minor cosmetic adjustments, as well as Oculus Dash support. But the bulk of the new content here is in the form of a demo Tunescape, which can be accessed from the Settings screen. It should help give you a few ideas about where you can start on your own creations.
