I am pretty sure I have a bug with PN4 and windows 10. When I choose the preset (festival), process my files then close and open PN4 and process the original files again, I get different results. sometimes it sounds extremely flat and dull (a lot of bass and dense lower frequencies. details vanished from the mid and high frequencies) and sometimes very crisp and transparent (same files and preset). double checked all settings in PN4 multiple times.
it´s very frustrating and I can´t rely on the results. (monitors: JBL LSR 305 + JBL LSR 310 S(ub), Beyerdynamic DT 1770 PRO)
Help is much appreciated.
