Recently i've started to notice that the data entry knob is not
responding properly. For example, if i'm going from pattern 126 to 127
and i turn the knob one click to the right, the patter does not
change, and i have to turn the knob a few times to get it to move.

Is there a way to fix this issue?

Thanks
