I recently registered my Logic Audio 5.5 Big Box and it says something like "cross platform"...do you know if that includes the use of the audio instruments (EX24, ES1, EVP88)? The reason I ask is that I tried to register my audio instruments and it was having trouble with the numbers....very confusing! I have since written emagic two emails and gotten no response.... ALSO...does anyone know if there is an upgrade to 6.0 version of Logic Audio and if there is how much is it and how does one get the upgrade? thanks!
