Click on the line with the ball to play the notes (the black rectangles). The notes are moveable. Their length is changeable by dragging one of the duration blocks (8th, 4th,Half, Whole) on top of a note block. The red stop block can also be dragged around.
There is a note playing project in the sample projects. Lots of features could be added to my project. Different instruments, ability to save the small sections of music and chain them together. Maybe the line with the ball should be draggable so individual notes could be played.
