my ultimate mute / umute performance key combo:

do NOT be in record mode ( = red light off)

have track 1 active
track 2 muted
track 3 active
track 4 muted

now press play, listen to your lovely tunes …

press performance and let go

hit function and hold

in the trig row on the bottom slide your finger from trig 1 all the way to the right through trig 4, (observe display if you do this tutorial repeatedly)

now let go of the function key !

baaaam, in your face… switch from melody and lead sound to kick and hats in an instance …

this also works without press and hold the FN key. … you will figure out …

side note: cudos for avantronica trying to lecture dataline on the A4 handling … *g (just kidding )
