 Ramps may also be used as a compositional tool, but more on this later.
 Note that a ramp requires two points - a start and an end tempo. The first tempo in a new session is ramped, but appears to be constant as it has no tempo to ramp to. It is only when you add a new tempo and adjust one of them that you will hear a ramp.
-The same applies to the last tempo in the session - it will always appear to be constant until a new last tempo is added and changed.
