Good morning/afternoon,

For the last 8-9 months we have been utilizing the X-USB expansion card in our x32 console to I/O most of our 32 channels through Logic on a Macbook Pro so that we can apply external plugins to said audio signals.  Recently, we began experiencing an odd degredation in the return audio signal that can last anywhere from a couple of seconds on up to a minute.  Resetting the console / laptop doesn't remedy the issue, and it has occurred to us even when there are no active signals being run through (e.g. between practice and the service and nobody is even on stage).

Attached is an audio sample highlighting the issue, with unaffected audio at the beginning and end for reference.

The audio clearly affects only those channels being processed in Logic and returned to the board, as the guitars (which are not processed through Logic) remain unaffected.  Also, at no point did Activity Monitor show the CPU being pushed beyond 20% utilization.

If anybody has a clue what this is I would deeply appreciate any insight.

Our setup:

x32 console running latest firmware
X-USB expansion card (USB 2.0 32 in/32 out)
15' USB 2.0 cable
2019 Macbook Pro
 - Catalina 10.15.7
 - 2.3 GHz 8-core i9 (9880H)
 - 16 GB RAM
 - 1TB NVMe
Logic 10.6.2
 - I/O buffer size 32 samples
 - Processing threads Auto
 - Processor buffer range Medium

Thank you!

I have a set of Samson C02 condenser microphones. When I plug one of them into my GoXLR Mini I get this noise.

I only get it when 48V is on(Condenser duh.) The sound in the file shows itself with 48V on and gain turned up pretty far in the software(60+ dBish.) I get it with both microphones in the set.

I get it when the GoXLR mini is plugged in the back of my PC, when it's plugged into the front pannel, when it's connected through a powered USB hub and even when it's connected to my wife's laptop. So I'm starting to think it's not my PC.

I do not get it if I plug in a dynamic microphone, even if I switch on 48V for no reason. 

I do not get it when I connect a dynamic microphone via a Cloudlifter, despite this device requiring 48V to add the extra gain.

I do not get this sound with the same microphones but another audio interface that is also bus powered(Roland Quad Capture)

Eternally greatful for any input anyone may have. At first I thought it was some sort of grounding issue with USB in my computer, but when the issue also cropped up testing with the wife's laptop my suspicions went elsewhere. Unfortunately these two Samson mics are the only condenser mics in the house right now. I tested with two different dynamic mics.

Greetings fellow tribesmen ^^ i own a behringerxr18 for about 7months and now when its on for a while, the fader turns to fly un and down . Mostly around the 13-16&aux channel as well as the bus sends . Has anyone had this experience?? Thanks ahead for your concern 

On my Mac Pro 5,1 2012 w/Mojve 10.14.6, the newest version of the Midas MR 18 is very slow starting up. I've included an .mp4 showing version 1.6 first, then the much faster version 1.5 second.

Anyone have any toughts on this. It's very annoying and makes no sense to have this happen after a long waited update.

Thank everyone!
