Acid XPress
Acid Xpress is free loop editing software that can be downloaded from Sony. It is a cut down version of Acid Pro software, but is quite adequate for the purposes we want to use it for here.Getting Loops
You will need some music loops to use with Acid XPress. They can be
purchased, but there are usually free ones that can be
downloaded from various sites. The free version of Acid XPress is
limited to 20 uses of mp3 files, but for our purposes here we will use
.wma files. In the free version
of Acid XPress you need to set your Sample Rate for .wma down to 32.000
Hz. (Note that you can use programs such as Audacity to convert
mp3 loops to wav files, or you can use
SuperC
to convert mp3 to wma in bulk)

To create music, simply drag some loops up to the left side of the track
area, then use the draw tool to draw out where you want your loops to
play. You can fade tracks in or out by hovering over the upper left or
upper right corner of a track until the cursor looks like this:
Then drag to create a fade.

Once you are finished, click File > Render As from the menu and save it as a .wma file type.
