jambient lets you fade LoopTracks up or down, or switch fade them, using simple mouse clicks. It also lets you Cross Fade  LoopTracks or sets of LoopTracks into one another.

To fade a LoopTrack up or down, set a fade value using the bottom pointer on the Volume Slider. The LoopTrack fades up or down until it reaches that value.

To switch fade, right click on the Volume Slider , or Loop Position. Switch fading fades up a LoopTrack if its inital volume is zero, and fades it down to zero if its initial volume is above zero. Switch fading also automatically plays and stops LoopTracks (LoopTracks stop when they fade to zero volume, and start playing when you fade them up). 

Change fade speed using the Fade Speed Slider.

Powerful fade effects can be achieved using the Gang, since fades in the Gang are transmitted to all LoopTracks controlled by the Gang.

Fade a set of LoopTracks to one level: If you set a fade value with the bottom pointer on the Volume Slider, all LoopTracks controlled by the Gang will fade up or down to that value.

Fade from one set of LoopTracks to another: If you right click on the Gang's Volume Slider, each LoopTrack controlled by the Gang will switch fade--LoopTracks that are playing will fade down, LoopTracks that are off will fade up. The result is a switch in the LoopTracks that are playing.

Similar fade effects can be achieved in Block Bands, since changes to the master LoopTrack in a blocked Band are transmitted to all LoopTracks in the Band. So you can use the master LoopTrack to fade all LoopTracks in a Band to one level, or to switch fade all loops in the band.
