Thanks to all that have replied.

Ron, The first thing I did was go out to the Presonus forum and it looked like the last post was from Aug; very strange. And now you confirm that they shut down their forum. What are they thinking??? Could this be my first real disappointment with Presonus?

But now after restarting my computer I'm getting a sample rate mismatch error message. Upon investigation I see that somehow the setting for the digital interface got changed from my Tascam to Realtek. I have no idea how this got changed. I certainly didn't change it. And I only got the sample rate error message this morning but my problem has existed for a few days. Thinking about this, it seems to make sense why no audio would play at all but that I did have very sluggish command response. I changed it back to my Tascam and things [so far] are working properly.

Brian, yeah, my issue is/was sporadic.

Matt, I have no trial plugins. Actually, as far as plugins go, I'm fairly "clean" with just 2 installed; Scaler and Ascension; neither of which were active in my workspace.

Billy, I haven't had time to read your post but I will.

So far, my system seems to be running stable but I am curious as to why and how the setting for my interface got changed and why it took S1 so long to give me a sample rate error. Maybe the root cause was a Windows update that somehow changed the setting.

As I continue to learn a new bass line later today, I'll be looping sections of that audio file which will further test its stability.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
