Check this out comparison.http://www.dtxperience.com/specs/dtx_vdrum_comp.php Pleas note, this is not to start a Roland vs Yamaha thread. I respect Roland products and own some of it myself. It just that I personally prefer Yamaha sounding modules. Some other forums bash any products that is not their own. I must give credit to this cite and the members for not getting involved with such childish bashing as Yamaha stands on it's own merits and needs not put down other non Yamaha products. As a side note, price wasn't a concern over my kit purchase. I really like the acoustic sounding samples Yamaha installs in their modules.
