That's what I was hoping. Should I just set that via my FxPlug's parameter UI? Or is there a proper, sanctioned place for this type global parameter to be set? (e.g.: a Preferences panel or something similar) Thank you very much for your help. -- Brian On Mar 19, 2009, at 4:47 PM, Darrin Cardani wrote: On Mar 19, 2009, at 3:55 PM, Brian Gardner wrote: Hmmm.... 1.

It's hard to say how you should handle it, as I don't exactly know what you're trying to do with it. But here's one idea: 1) In your plugin, include a custom parameter that will display and control the global data 2) Have each plugin instance subscribe to notifications from the singleton object 3) Whenever the user adjusts the custom parameter in one instance, update the singleton and have the singleton notify any listeners 4) When the listeners are notified, they update their UI to match the current state of the singleton You can create a singleton object that the others will communicate with. For example, you could have something like this: (Note that I didn't actually compile that! But that should give you an idea of how to do it.) This email sent to site_archiver@lists.apple.com
