you've been on this forum for a while now haven't you?.... i'd have thought you'd know better than to just copy tracks and think it's actually doing anything for you at all
. yeah, as Ken (abigailwilliams) says... play it again. a copy of a track will simply have the effect of making the original track sound a bit louder. panning the copy will have the effect of making the original sound seem to be panned. so, the similar results could be had by simply raising the volume of your original track and panning it in a bit.
sometimes people will try this trick and offset the copy by a few miliseconds... this sounds like ass. just play it again, there are no shortcuts. this has all been covered extensively in past threads.
