How do I add Reverb to Microphone of the A/D input?
I need a bit more information about what you are doing. As the article points out, if you are performing "live" you will want to set your MOXF so that you are using just one set of stereo Outputs (1StereoRec). This allows the A/D INPUT Part to go through the SYSTEM EFFECTS (Reverb and Chorus). If you are recording to a DAW like Cubase then process is a bit different. Please provide us a bit more information about how you want to use the microphone and we will help translate the referenced article "MOXF Setting Up a Microphone, Guitar or Other A/D Input"
Are you performing live?
Are you attempting to record to Cubase?
