I don't think that's it. The only choice that makes sense to me is Internal, as I don't have any other digital device connected, just the 828mk2 to the iMac. What's happened now is, increasing the buffer size to the max (1024) helped. I was able to record 10 trks at 96k/24bit in 10 minute chunks a couple of times. Then the glitches started to reappear both in playback and recording. I powered things off and tried lower bit rate settings. 88.2k/24bit appeared to be doing fine for 30 minutes, however some stomping around on wood floors near the mics triggered some spikes in the audio signal, and then the spikes continued on their own like echos or noise in the signal, even though the stomping around had stopped. I saw this happen a couple of times.mikehalloran wrote:At first glance, looks like a sync issue which means the clock.
But good news, at 48k/24bit, I've had no problem. I've recorded 10 trks up to an hour without issue both yesterday and today. I overdubbed two trks on top of that and that went fine as well. So, whatever the issues, the sample rate looks to be a bottleneck. Pretty surprised at this as I thought there'd be plenty of bandwidth throughout my chain (828mk2 fw400/800 cable, fw800-tb2 adaptor, tb2-tb3 adaptor, iMac). But that's where it stands now. I don't think sync would be an issue if adjusting sample rate is having such an effect. Any other thoughts?
In the end motu preventing me from updating to Catalina is after all maybe not the worst thing that could have happened to me, looking at all the problems Catalina still has.
