From my testing experience, Registration Bank (.RGT) files search for (and link to) the actual given Style 'NAMES', and don't rely on the randomly assigned style location 'number position' method the way the MusicFinder Database 'style retrival' system does. The Tyros doesn't include memory stick support, but I've noticed that even if a Registration File is moved, or loaded via remote media (floppy diskette, etc), it is still able to consistantly find (and load) the correct style in user memory or HD. - Scott
