  com.frinika.sequencer.model.tempo.TempoList

All Implemented Interfaces:

java.io.Serializable

public class TempoList
extends java.lang.Object
implements java.io.Serializable

Maintains a list of tempo changes. Tempo changes occur at midi ticks ( an tempo changed is fixed to a tick) Inserting a new tempo change sets a dirty flag. If need be the real time of the events are reconstructed if the dirty flag is true.
