To the best of my knowledge the outs are still hot when overbridge is running.

It works fine, just make sure you tick the right checkbox for this in the settings.

Is it possible to use the 1/4 inch audio outs while also using audio over usb via overbridge for either of these devices? I'm wanting to route audio through effects pedals into an interface and also record the dry signal simultaneously over usb. This works fine on the Analog Four so I'm not sure why it wouldn't on the smaller boxes.
