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.
