-== Metronome ==
-
-This plugin demonstrates tempo synchronisation by clicking on every beat.  The
-host sends this information to the plugin as events, so an event with new time
-and tempo information will be received whenever there is a change.
-
-Time is assumed to continue rolling at the tempo and speed defined by the last
-received tempo event, even across cycles, until a new tempo event is received
-or the plugin is deactivated.
