Newbie Question On Midi Output Options

[Oakland Stroke]

Maybe I'm missing a concept here, but . . .

I am using OSX Core Audio and Core MIDI. I have a Midisport UNO interface to control the instruments in Reason and Logic. When using Logic, the output of my audio channels and audio instrument channels plays through Core Audio into my connected speakers; however, the MIDI channels play back through the speakers in my MIDI keyboard.

I have looked through the Audio/MIDI setup utility and Logic's Setup Assistant, but I do not see a fix.

Advice appreciated.
