Richard,
the MFC10 is set up to work with 10 preset banks in the Tyros. If you go into the midi page and select a preset for the foot controler, there is another tab called MFC10. Going to this page you can see how all the buttons are factory pre programed on the Tyros. The Behringer, which is about 1/2 the price can be programmed to work but will need some work.
