No sound output thru headphones of midi-controller keyboard

Hi,

I'm new to Logic and am encountering the most basic of problems: I can't hear any sound from my headphones of the midi instruments played with my keyboard controller. I ran several searches in the Logic Discussions archives, but didn't find anything about this particular scenario...

My keyboard controller is connected with a USB input, and the drivers have been properly installed. I cued up a new project, set my audio preferences for headphones out, checked those settings via i-Tunes, then selected a software piano and laid down a track whose volume and notes are both registering fine. Everything looks like its working great -- I just can't hear the signal.

With this same set-up of my keyboard controller, I opened up Ableton Live and played a software piano instrument there, only this time I could hear everything fine.

I flipped through the midi sections in the User's Manual and carefully the scanned the Logic interface for something to toggle that I may be missing, but so far no luck.

Please tell me what I'm not doing! I know it's gotta be super basic...

Many thanks....

Chris
