Not of critical importance, just asking the profound depth of technical knowledge i see on this forum just in case it could be done~
(Programatically?) is it possible to replace the 230 styles in the default banks in a yamaha keyboard (psr s670) by custom one. (I edit styles to trigger different bass lines based on chord types - this cannot be edited onboard - casm limitations)
or Maybe point the 6 buttons dedicated for styles, e.g "pop&Rock", "ballad" etc directly to some user folders on USB.
My point is to be able to used those buttons as "quick links" to customs style [hierarchy] which could be changed by Registration Bank.
Possible Scenario:
Say in Church one could play only European or Baltik Music, but in other different Ceremonies maybe Indian, Arabic, or different local Ethnic styles in my country (then All the Panel Styles are not used .... kind of wasted!)
