The unregistered xtra will work in Director without restriction except that value lists returned by ampGetCurve(), ampGetMonoCurve(), ampGetSpectCurve() and ampGetSpectMonoCurve() are limited to 20 elements. These functions are not essential in order for you to evaluate the xtra. The xtra must be registered in order to work in Projectors and Shockwave.
