Hi everybody, this is my first topic here!I'm considering to buy a madiface to use with my macbook pro (late 2008) 15" which has an expresscard slot with a soundcraft si compact.I read here in the forum of some user having troubles with this combination for the expresscard slot of the macbook but I used it with usb cards and firewire cards without problems.I would like to know if anyone here had luck with this combination or if you suggest waiting for the new usb one. Will the new usb one have comparable performance to the expresscard model?I would need to have near thirty channels of audio going in or out and would like to have latency low as possible.

Thanks in advance for your answers,nice forum! :-)
