I need help, samples won't assign to pads

I have double tapped rigorously and clicked the knob and it won't assign them. Please help

Could you elaborate on the exact step by step process? Your description of the problem is too vague.

Standalone or controller mode?

What firmware version?

If controller mode what computer?

Have you tried following steps in the manual or a YouTube video?

Can you record yourself working through your process and post it so we can see what you are doing?
