lots of people have different ways of using the mxer to increase/decrease the volume of a track,

in contrast to dj ze migL method i use the gain all the way. When im happy with the cue and the beats are right i turn the gain all the way down and wack the fader all the way up. Then use the gain to trim it into the other track.

but dont use my method because as ive learned this only works well with my mixer. Like dj ze said different mixers create different styles.
i should really change this cause i know this would cause problems in a club or different mixer, but try it any ways.
