This picture shows one idea for a representation of a loop. On the top left, there is a circular ring of segments with a hi-hat image inside of it. The image inside the ring represents the kind of sound you are working with, in this case, the hi-hat. Clicking on the ring expands it into the loop builder, which could use Jon’s idea as the interface (see previous post). Also, you could add loops together (shown in the middle of this picture) to form larger (i.e., longer in time) loops.
