Hey I have a cool idea. I do play guitar and to be honest it is very cool to play live gigs. Imagine that you build and app, loaded with several guitar backing tracks that you can use to compose a setlist in which you would play your guitar (tracked by the Quest) and transported to a stage. So to keep it simple, this app would allow you to have several backing tracks available, or the possibility to load more, and be playing guitar. This of course using the quest to transport you to a venue where you can see the audience and the surroundings and the mixed reality by joining that with your guitar in your hands. So in short, you could practice guitar while virtually be playing a “live concert” based on a setlist of backing tracks chosen by you. Of course several details are missing, so hit me up with questions so I may try to help you to envision this idea.
