It seems like such a simple thing. You've
recorded your track, arranged it exactly the way you want it, applied
the requisite effects and carefully mixed everything together. All you
need to do now is fade it out at the end - and possibly in at the start -
and you're done. Simple, right?
In
practice, yes. But while creating them is a perfectly straightforward
process, fades can have a huge impact on the mood and feeling of your
track. There's plenty more you could be doing with the fade function
beyond just clicking and dragging a straight line.
