Hi Darrin,
you mention and I quote
> 1) You can get the current playhead time by using the
> -[FxCustomParameterActionAPI currentFxTime:] method.
A) The FxCustomParameterActionAPI does not have a currentFxTime - only a
currentTime which is very diff. from currentFxTime
B) Notice the little colon after currentFxTime in your answer. It is missing a
parameter. The method cannot be called like that. It needs a parameter which
makes not sense when getting a value from a method
I wrote another mail regarding this possible bug… Could you please provide a
workaround, thx
