This app offers an interactive and immersive experience with thousands of song options, promising endless hours of enjoyment. While we haven't tested it with external MIDI controllers, other reviews suggest that they significantly enhance the realism of the experience. The mixed reality feature is impressive, though the VR backgrounds, while nice, do not achieve photorealism. An improvement could be made if the virtual audience danced in sync with the music, adding to the lifelike quality of the performance. Overall, this app is a fantastic example of how music, mixed reality, and entertainment can merge to create an engaging and immersive experience.
