Trying to retrieve the API within the parameterChanged function always yields NULL. What is the appropriate function to retrieve the parameter setting API? Can it be cached? In what context is parameterChanged being called? That is, is this in response to an event in a custom parameter or on-screen control, or just a value change for one of the standard plug-in types?

Parameter Interaction When a user changes a parameter control for an FxPlug plug-in, the host application calls the plug-in method -parameterChanged:. In response, the plug-in can change the state of other parameters. For example, if the value of a toggle button changes, the plug-in can hide or reveal other parameter controls, or change their values. Note: In FxPlug 1.0, the -parameterChanged: method is included in the FxFilter protocol, but not in the FxGenerator protocol. Generator plug-ins that need to respond to parameter changes can use custom parameter UI. © 2005 Apple Computer, Inc. All Rights Reserved.
