I just got an M5. Assuming you have everything set up right (program change map / midi transmit etc) I can see why it would be annoying that the TF doesn't transmit program change info when changed from a MIDI controller.
BUT I guess the question is, if you're using a MIDI controller why not operate the TF and the M5 independently anyway? It will have the same effect as the TF controlling the M5 and will take just as long to set up.
