You'll find detailed instructions on assembling style parts, that is, moving one part of a style to another style, as well as details on how to edit accompaniment styles at http://psrtutorial.com. These lessons cover the PSR-2000, but the Tyros operates the same way so the lessons should be able to help you out.

Here is a direct link to the Assembly lesson: http://psrtutorial.com./Lessons/L_Personalizing/LP_CrStyles/LPC_Assembly/lpc_assembly.html
