Jamfetti
I created instruments for people who have no idea how to play one I designed Jamfetti so that anyone could jam out and make music even if they have no experience. It works by doing the hard part for you. Every note you play is shifted imperceptibly to land on beat. Every note also comes from the same scale so that they sound great together. You can pair any instrument with a number of cool 3d visualizers. Let me know what your favorite pairs of genre and visualizers are!
