The Mackie website is hopeless when it comes to determining compatibility. Will the original, Emagic-branded, Logic Control unit work with Logic 8 or 9? Will you get full functionality out of it (channel names appearing and time code showing up properly, for example)?
Edit: It was originally released with Logic 5 -- back when Emagic wasn't owned by Apple, that's why I'm wondering if compatibility has been maintained as Logic progressed through its versions.
