Opps sorry, forgot the computer specs...
Windows 10
Protools 2020.5
Focusrite 18i20 1st Gen audio card with current drivers
Yamaha HS-8's
The issue isn't in my monitors. I can hear it in headphones as well. I reloaded PT and updated all my drivers.
This issue has always been present but I never realized it was an issue until today when I was checking a mix with my Analyser and noticed the missing frequency. I went over everything I could think off but I can't find anything that could be causing this within the software settings, plug ins, folder structure or PC itself. I even checked my guitars' wiring and cables. It all checks out ok.
