I'm new to recording and computers, I have an imac with 8gig ram, running Logic Express 9 and Pro Tools Mpower 8. I wound up with two interfaces, a M Audio Profire 610 and a Focusrite Saffire LE. Is there a way to set them up so I can switch back and forth between the two without having to disconnect and reconnect the firewire cable each time? The mac has only one firewire port, would a firewire hub work? Daisy chain does not work. The Focusrite does not have an on/off switch, the only way to turn it off is to disconnect the power. Any suggestions would be greatly appreciated.
