You say it "doesn't work." This can mean almost anything, but I assume that you mean you have no response from the MF.
What presets are you loading on the TF and what are you trying to load on the MF, and how are your MIDI maps set up? Give an example of the program number on the TF, the corresponding program number on the MF, and the resulting TF XMT MAP and MF MF RCV MAP entry.
Have you tried different cables ? Presumably they are connected IN to OUT and vice versa.
