Hi All. I am going to buy PT01, please help me with my dilemma.. Is there any problems with scrathing on 12" vinyls? I got some i didnt sold. I also got old traktor scratch vinyl. Is there any way to make it works (on Adroid App DVS like). A Saw Mixfader app is working with serato and traktor vinyls, but i am not going to buy it soon.. maybe 'Edjing Mix' ?
