Hello TheEdyamine,
Thank you very much for reporting us your solution of the scratching issue. We are glad to know that you successfully found the answer by yourself.
Yes, you might have presses [Shift] + [Slip] buttons, which switches vinyl mode on and off. You can find it in page 11 of the Operating Instructions from the link below.

If having any issues, we would like to humbly advise all the customers to read the Operating Manual of your products in our website like TheEdyamine did before reporting to us or sending your unit to a service center.
Thanks,
CRM, Pioneer DJ
