Well I found a new habit of the DL. I was testing the record/playback levels and before I knew it I had no meters. I guess I complained too often about them so Mackie must have fixed that problem I now have no meters. I tried task switching no luck. VoiceRecord play worked just fine as did AudioTools indicating my signal source was just fine. This clearly puts it in the category of UNRELIABLE. A restart of MF fixed the problem.
