@charles-t Go into the program settings (gear icon in the top left), go to the tab "Audio / MIDI", select Magix Low Latency as your ASIO driver. Click on the "Advanced..." button which will open the Magix Low Latency driver settings. On the left side you will see a list of all your audio inputs and outputs the driver will recognize. Activate the inputs and outputs you want to use. You can click on the wrench icon on the right side of the driver settings window to get a more detailed list.
