Both setups.... make sure Force Realtime mode is ON in SAC and SAWStudio... see if that helps.

1- Not periodic, but frequent audible glitch-sounding stuff. They don't get printed and don't affect the tracks in SAW. But it seems there's background stuff messing with the audio. Not losing digital sync. Raising buffers might be a quick fix, but more than 4x64 becomes an issues down the road. I should be able to do that without a sweat.

I was getting the occasional click on SRP on my presonus 32sx if it occurred, it would usually be a second or two after starting playback - also didn't print, I'm just recently tracking it down. In the system device manager window, the driver shows twice, once up under presonus - but again under 'sound, video, and game controllers'. It turns out the second entry is for wdm overlay. If you have that, try disabling it and seeing if the clicks clear. No windows audio anymore (as I have the built-in audio disabled in bios) - but I don't really care (but in your case, you have lots of hardware to choose from). Anyway the asio (portion of the) driver still works, and now sounds fine.

Now saw is complaining about no MIDI - evidently I had the presonus selected in saw. I don't know if I can separate only the wdm and keep the midi intact - that experiment is for down the road. Anyway, it is one thing you can try.

The new (old) pc had its first go at a tracking session today. It's only about 80% ready, really.
The session was minimal - stereo keyboard (USB feed) played into piano sample, through SAC, recorded to a single stereo channel in SAW.
One vocal overdub - same routing. All relevant drives are Samsung SSD. (Wonder if Samsung Magician needs to be turned off)...
Only one Reverb (Vegas DX plugin) on an aux for tracking vocal, plus SAC channel strip EQ and Comp.

The recording and basic edit of takes went well. But I've got two issues at this basic level that I need some advice about, for things to look for first in fixing what shouldn't even be issues at this low level.

2- Recording meter in SAW went black on me a few times (that's a first in over 20 years). Switching back and forth, from SAW to SAC and back fixed it. Also, channel strip in SAC wouldn't always update properly. Sometimes it would simply display the wrong channel and a few times wouldn't show the EQ settings. F-key switching would bring it around, but not always the first try.

Any ideas would be appreciated. It's going to be 3-4 days before I can spend serious time on fixing things.
