16 Levels Tuning

For some reason when I go to 16 levels (assign 16 levels) (param: note variation) (type: tuning) I cannot change the original key pad #. My cursor will not go to that column.

What am I doing wrong.

im not in front of my mpc, but maybe you just hit that pad you want to be the pad assigned to the original tuning?

yeah, you just need to hit the pad you want to use 16 levels on
