mixing trax??

having a headache cause trying to make live performance with the 1k and cant find a way to mix trax.
ej. : got a drum loop divided into 4 pieces--make a recording using the 4 samples/pads into 1 track (this makes the complete drum loop)-----while performing i wanna change the drum volume and cant make it in a proper way cause i have to take care about the 4 samples instead of the track.

any way to do the trax mixing?

pd:sorry for my english.

mode>mixer

for sure¡¡¡ but can only manage pads..........i wanna manage trax.

track volume is on the main screen. you got os 2.1?

that's it¡¡¡
excuse the question
thanx pad-o
peace
