Hi - hope you're good. I've recently traded in my old macbook pro for a new generation and, since I no longer have the 400 firewire port, am daisy chaining my Mackie 1220i Onyx into my external hard-drive's (LaCie) 400 port, and then the hard-rive into the macbook pro's 800 firewire port. This is a first for me. I can see the sound card options in my Audio Midi set up and have selected both the input and output routing for the Onyx. If I play a wave file, say through Quick time, the signal is routed through the Mackie. Yay. If I play audio through Logic, the signal comes through my workbook's speakers. Boo. The audio preferences in Logic show the Onyx as the input and output routing, with appropriate latency measurements. The sound function buttons (F10-F12) are disabled, again indicating that the Onyx is the routed sound. So....I know my machine is routing to the Mackie...but just not through Logic. I've got to be missing something here. Any suggestions? Thanks!
