When you provide additional sounds for the QuickTime music synthesizer, you can simplify the creation of the necessary instrument resources by using the base instrument component. To create an instrument component, you create a component alias whose target is the base instrument component. The component alias's data resources specify the capabilities of an instrument, while the code resource of the base instrument component handles all of the component requests sent to the instrument component.
For information about component aliases, see "Component Aliases" and "Using Component Aliases" .
