Giovanni, Try this site – be prepared to receive hundreds of styles. Not all good and some fantastic. This site will give you all the information you need on just about every subject.
The Kn7000 is a fine keyboard for big band music. The Tyros2 plays big band with a contemporary flavor – more push and drive. I use the registrations to achieve what I want from the styles, cut some of the instruments and adjust volumes to my taste, and I select and adjust the right hand instruments.
