Hi Bill,

if you purchase a yamaha-style you may be right ( depending on the EULA of the manufacturer IF it´s NOT Yamaha).

Have a look to Yamahas "Online Member Terms of use", Part 4 :

"...You agree not to copy, reproduce, republish, modify, distribute, sell, rent, lease, loan, transmit, display, perform or create derivative works of the content of this Web Site or otherwise based on this Web Site, the software used, all other materials, text, graphics, logos, images, audio clips, music, data and other materials used in connection with this Web Site or other web sites made accessible by Yamaha, or the arrangement of these materials or content, without the express written permission of Yamaha or as otherwise permitted by applicable law..."

The same applies to the "factory-styles"
