Howdy, and thank you for your quick reply!
Here's some more information: The H8000FW is getting a clear audio signal from the mic/preamp out of Analog 3 in. I can hear sounds with/without effects through the Eventide just fine from my iMac.
It's only when I set up an Audio Track i Logic that there's an issue – the Eventide is showing an audio signal coming into Analog 3 just fine – however, the Audio Track in Logic is not getting any signal.
Any new thoughts?
