Can't Get Midi to Echo

[Batch151]

I'm going nuts here. I cannot get midi from my controller to echo out to my synth while recording. This worked yesterday, but not today...

I have my midi controller plugged into my midi interfae. It is recognized and I can actually record midi to Reaper, but I cannot hear it. When I play it back, I hear it, but not during recording.

I have the midi hardware out set to my midi interface for the midi track. The synth is working and plays itself just fine. No sound or midi activity when I try to record or play directly from the controller.

Any ideas?
