Sending midi bank/program changes

[tobsboy]

Hi
     I'm trying to control a korg Kronos from my tyros 5.  I t's straightforward to adjust the midi settings so that note data is sent on the required channels but I cant figure out how to send particular program change data. You can, of course, send some program change information by simply changing programs on the tyros, but I was hoping to call up specific changes with style variation, ots or registration changes. Any info on how this might be achieved would be welcome.
