How do we interact Audio Server PlugIn from other app via apple events

I try to pass some information to Audio Server Plugin via Apple Event, in the event sender application, I tried AEBuildAppleEvent with the plugin's bundleID, the plugin is running correctly, anyway, when I call AESendMessage, it always return -600 which means procNotFound, any idea? and I'm also trying to send to coreaudiod for alternative and check if that could work, but it is a daemon w/o bundleId.

I know there are other ways like socket and shared memory etc can do the job, anyway, if AppleEvent work, it will be pretty neat!

Thanks
