Click the instruments to start and stop them. They're all synchronized by the conductor, who broadcasts each beat, each bar (every 4 beats), and each section (every 8 bars). I also created a "play major scale note" block so that you can easily play in the key of C (so that, for example, a C major scale is 1,2,3,4... instead of 60,62,64,65...). One way to remix this project is to make your own sprite to add to the band, and make it play something each beat or each bar. maybe some more percussion instruments, or other wind instruments, or something else entirely? You can also add dancers, that don't make sound, but animate on the beat.
