Rekordbox DVS Issues

 Hi,

have recently purchased a djm 450 and I have 2 Technics 1210.

Since I update to rekordbox 4.3.0, and the firmware of djm 450 I have 2 kind of issue:

1) The bpms won't lock properly and when I play the file the sound crackles;

2) Bad sound when I record a vynil via Rekordbox.

Regards

Antonio
