Paul, It will only work if you’re working within an FxPlug 3-style plug-in. Also, be sure you’re asking for the right thing. Your query should look like this: id<FxParameterCreationAPI_v4> paramCreateAPI = [_apiManager apiForProtocol:@protocol(FxParameterCreationAPI_v4)]; I sometimes update the left-most one but forget to do the right-most one, or vice-versa. If the above doesn’t solve your problem, show me what you’re doing and I’ll see if I can spot any obvious issues. Darrin On Apr 25, 2014, at 12:23 PM, Paul Miller <stelefx@gmail.com> wrote:

I'm trying to query for FxParameterCreationAPI_v4 in Motion 5.1 but it's coming back nil. Is there something else I should be doing to enable support for it? _______________________________________________ Do not post admin requests to the list. They will be ignored.
