Save the styles (or Registrations, M Pads or Songs) to a USB stick,
On a PC, use the Windows file manager to view the files on the stick,
Change the number at the end of a file to the desired number shown on the Icons list
e.g. the Style '6-8Modern.T160.prs' uses the icon named T160 which is the picture 'Microphone'
I want to change that picture to a different Microphone which is not available anymore on the Tyros 5, number S828
So, replace the number T160 by S828. Copy the files back to the Tyros replacing the original ones.
That should do it.
