Yea you are creating a feedback loop - you probably don’t need any of the cue volumes turned up for this set up, leave them down.

You could try it simpler, without the feedback loop. Unplug the MD outputs from the computer and get it working right with headphones first. Then figure out how to route / configure yer computer setup.
Also, check your ILEV.[/quote]
Yeah I left them down for the recording aspect. It was just a test to see if there would be any playback.
I tried recording with the ILEV both at 0 and at 64. The only thing the computer is connected to is the USB routed from the audio interface. Technically the MD outs are only connected to the audio interface. I may be misunderstanding what you are saying though.
