Rekordbox 6.7.1

hello about rekordbox unfortunately, I am the only one who dominates this program in turkey, everyone is waiting for help from me when there is a problem, pionnerin's own distributor in turkey has never answered these issues or solved the problem 6.7. there was no problem at 6.7.1. there are distortions in the sound, the same songs, the same system, there are fluctuations, I use ddj 1000
