Musicrow tell us that Shaker Maker can produce a wide variety of shaker sounds, (there are 16 presets), and you can shape your shaker to sound exactly the way you want it to.
 

For using Shaker Maker you should put it in the insert slot of your audio track, then load a drum loop or any other rhythmic audio file to this track. You can also connect a microphone and use your own voice as the source for your shaker rhythm.
