The best thing for you to do is to map each button to a SPECIFIC "CUSTOM" command in girder, that is, instead of mapping button 1 to "PLAY", map it to "BTN1"... do that to all 14 buttons (up to "BTN14").. of course, those commands don't exist in RR, but that's when you go into ExecTBL.INI and define their functions, best of all, on a PER SCREEN BASIS. This allows you to use your 14 buttons for completely different functions on EACH SCREEN, for instance:
and so on.... note that button 1 above will be "play" on the audio player, "browse" on the audio browser, and "pause" on EVERY OTHER screen. You can define the functions globaly or on a per-screen basis until you've achieved the desired setup. This eliminates the need to use "groups" in girder and eliminates any doubts as to what function will be performed by each button.
