I wonder if you could do the feedback mechanism in a more subtle way, for example by pairing the musical composition component to an interactive activity like playing an action game, where movements and so on in the game trigger a response in the music.
There are lots of games that do this kind of thing at a rhythm level, like Necrodancer and more recently BPM [1], but I think there'd be the potential to do a lot more with it than just rewarding beat-alignment with a pre-cooked solo that blazes over top of the base track.
