Ableton & Analog Heat – glitches

Hi guys- just bought an Analog Heat and using it via USB with Overbridge in Logic. However, as soon as I engage/make Overbridge active the audio running through the channel is muted. It’s weird because in Overbridge I can see the waveform running through, but I can’t do anything to get sound.

Dumb question, but you can both send and receive audio via USB correct?

So, to answer my question above, I stupidly didn’t have overbridge mode engaged. Now that I’ve done that…I’m still getting no sound output. When the Analog Heat is connected via USB it crashes my Apogee Duet/Maestro software every time. Anyone else experience that? Thanks.
