I’m missing something simple and obvious in my setup. I have a Steinberg UR22II interface to my Windows 10 PC running Cubase Elements 12. The interface’s audio output runs to a small stereo mixer. Cubase Studio Setup has the Yamaha Steinberg USB ASIO driver and the Audio Connections have the UR22 as Inputs and Outputs. I have a Modwave synth connected to the audio inputs of the UR22 and I can hear it as a Mix Input on that (in mono) but there is no output coming back from the DAW - if I turn the Mix control on the UR22 to DAW, the synth is silent but other audio from the DAW is present. Once I record a synth audio track into the DAW, I can play it back and hear it.
I want to monitor the synth’s return from the DAW as I play (I know there are latency aspects to consider) but it doesn’t appear. What have I set incorrectly?
