Abstract
Abstract A method and system for providing synchronization of the timing of various multimedia events, including an audio event is disclosed. Clock objects are defined in the storage and associated with an internal or external source of current time. The clock objects are able to be displayed on the display, but can be hidden once their linkages are defined. One or more multimedia objects representative of audio, visual or other multimedia events, including an audio object, are defined and linked to a particular clock object or clock objects. Then, a processor synchronizes the multimedia objects, including a MIDI data object, with the associated clock object or objects. Finally, the various multimedia events are performed in synchronization with their associated clocks. The multimedia objects, including the audio object, may include external multimedia sources managed by the computer system.
