**CorOS Version:** 3.3.0

somehow the new update broke my presets. Right now, each of them has a metallic, distorted echo that wasn’t there before the update.

Today, after the new 3.3.0 update each of my presets has this weird metallic/distorted echo.  
The echo is present in all of them; in some, it’s more audible, while in others, it’s less noticeable, depends on the gain I guess. I recorded a sample of it, but I’ve tried everything to fix it. I’ve had the Quad Cortex for a couple of years, and I’ve literally lost my mind trying to figure out what’s going on. It was 100% not before the update because I was just using it.

It’s always there when playing, at the end it’s quite loud

Did you check if the input gain was reset to a different value by any chance?

That’s a strange one. Is the noise still there in clean presets?
