( 16 channels of simultanious audio) But when I tried to record the band that evening, Logic pro freezed an gave me the 'disk is too slow or system overload error'. I tested it first at home with blank audio regions, and it recorded fine on my internal harddrive. I'm recording with an Presonus Firestudio project and a Presonus Firepod, set up as an aggregate device in audio/midi setup. I'm having lots of trouble recording live bands with Logic pro 8
