Fading in and out
If you want to fade out every instrument pull up the master track. It is under the Track menu. From there you click a spot on the line where you want the fade out. There are 2 spots, where the fade out begins and ends.
If you want to fade out one instrument you click on the down arrow on the tracks label thing and make sure track volume is selected in the pull down menu. Then you do the same thing as the mastertrack only this controls one instrument.
