No, I don’t think I’m the only one having a problem with the sound level. Look at the link I posted earlier on the VDJ forum and by searching for “low sound prime 4 vdj”, you’ll see that I’m far from being the only one with this issue. So I was wondering if there had been any modifications with more recent Prime 4s, because mine was purchased at the very beginning of its release. And if you don’t have a noticeable difference in sound volume with Serato, it means that something has changed for sure, because you would have noticed this problem. So I think I will stick with Serato since it’s just occasional. Thank you for your feedback anyway."
