I know that it has a maximum of 8 tracks, I'm not sure if you can record all of them at once. I'm also not sure of the recording speed. I used to use it with the apple sound manager on my mac and the sound was not too good. When I got a SeaSound, sound card, I had to update to cubase vst, because cubasis doesn't have asio drivers.
By the way, Cubase is working horribly with my system.
