Reply to VCI-400 Vinyl mode sounds distorded when trying scratch

Hi, i just got my VCI-400 and im building my own mapping from scratch *yes every button, knob, and fader*

so when it comes to map the jog wheels, i just do my the regular "jog touch"

so the track stops when i touch the jog wheel and scratch by moving the jog wheel back and forth....it does scratch HOWEVER the sound is distorted abit. It's not clear like it is suppose to be.

so when i use the mouse to hold the track and move it back and forth (thats scratching with the mouse) the sound is nice and clear.

so for the heck of it i downloaded a mapping from someone else....and that mapping produce nice and clear sound.

what am i doing wrong with my mapping?

HELP
