I had Hercules rmx with the basic version of virtual DJ, but then I upgraded it to the newest version of virtual DJ pro. Now the problem is that while mixing I notice the change in sound quality, there is no issue when I play the song in same pitch but when I increase or decrease the pitch of the song the sound gets deteriorates. Example: I a playing song at 128 bpm and I want to mix the song that is 130 bpm. I adjust the 128 bpm sound to 128 bpm and the sound will be deteriorates. So I just want to know that is this common problem in virtual DJ, how to fix this problem. Please guyís help me in solving this problem.
