This is one great machine.  A vast assortment of sounds are possible; there are 50 pre-sets so I can "plug and play" and there are a virtually infinite combination of user-preset options available.  The manual is thorough, but there are videos on-line that provide excellent tutorials for those who aren't fans of reading tech-speak.  This is a great way to improve timing and coordination, using as a substitute / second drummer.  Foot switch options let the user start and stop without needing to use hands to start-stop. Second foot switch provides A/B functions.
