Friendly bump:

does anyone use "FxParameterSettingAPI_v4 setStringParameterValue: toParm:" successfully?

N.B. I tried both, kFxParameterFlag_NOT_ANIMATABLE and kFxParameterFlag_DEFAULT, but no luck.

When are you calling the function to set the value? IIRC, you can only call that in response to a parameter changed event, so you have to set the default value properly when you create the parameter.

Thank you. Indeed, it works inside the parameterChanged. I tried to call it in finishInitialSetup... But that leaves me that problem: To find my generator inside the XML I have to add a parameter containing a UUID (the generator UUID only references the motion template, but not the actual video on the timeline). So when I add a clip to the timeline, I want to check, if the parameter is set to a valid UUID. If not I generate one and set it to the parameter. I need to differentiate, if the clip was created manually or restored from a previous session. I tried to do this in addParameter as default value, but it is only called once per session. Further instantiation of the generator does just a clone from the first created instance. There also seem to be no callbacks, where I could hook in with that... Any ideas how to achieve this?
