Ok that's working fine, but I was running only one turntable, now I've got 2, I only get track A or B depending on whichever is 1-left and 2-right.. I can hear the second track in my headphones, but when I fade it over.. nothing. Tried install setup many times, with all options but no luck

Any advice?
Also, the sound output is out of sync with the on-screen cues (the peaks that move when you swing the vinyl back and forth), and the 'beat' changes place on the vinyl with every move (especially bad for scratching) - can I make this more accurate?
SO sorry to overwork you guys - you've been fantastic so far!
Best,
Sam
