Stand-alone Orbit Slider and integrated Orbit Slider are not 100% the same.
Orbit has moved to Foundation!
Greetings! We here at ZURB love Orbit so much, that we have included it in our (Awesome) rapid prototyping framework Foundation. We will no longer release updates, or provide support for this version. Thanks for understanding!
P.S. WP Orbit Slider is what I have been recommending for users with my Theme too. IMHO one of the best around.
