Mix Down All Channels?

Anyone know how to select all the channel in the mixer so you can turn all the levels in that program up or down at the same time like in my 2000xl? Im tired of turning down every pad seperatly.

mode pad 8 mixer: shift and bank button selects all 16 pads of the bank.

os1 GPE mode pad 11: f5 "out" select whole and adjust the level

os2 PGM mode pad 8 :f6 "out/fx". press shift and f6 turns "whole" on then you can adjust values in the level field
