Hello....I'm in the process of upgrading my PT setup. Currently using an older MacBook Pro and Firewire 1814. Getting a newer Imac with FW 800 and Thunderbolt ports. I'm assuming I can use my FW1814 interface that I currently have (with a FW800 to 400 adapter) but want to upgrade to an interface that has 800 or faster capacity. The ones I've seen only have 4 inputs, and I'm used to having 8 that I can run simultaneously, mainly so I can record drums. Any recommendations for interfaces?
