hi, i run logic on an ibook 500, with a 60 GB firewire hard disk. my audio interface is the emi 2/6, and it is working fine. but currently i am trying to master my tracks on the ibook, and found the amount of audio tracks at playback not quite enough. so, would a firewire interface, i have the motu828 in mind, enable more audio tracks and more plug-ins at play back? or is it the matter of the computer, ram, and hard disk? thank you in advance. nathanan
