Hi, I need a soundcard to use live that will allow me to have a stereo click track in my in-ears as well as outputs to run backing tracks, vst samplers and vst instruments. Specs: - 8 1/4" outputs - One MIDI In/Out - One assignable headphone jack - No inputs needed. Suggestions? This will get heavy use for tons of touring. It will be used on a MacBook Pro running Leopard. thanks!
