Unfortunately, you are probably doomed to be disappointed.
The TF will support either (DIN5) MIDI, or USB. It won't do both.
This is because the USB was initially implemented mainly for updates, it was not really intended for use as a MIDI controller.
You might consider that when the TF was designed, almost no stompboxes had either MIDI or USB.
Obviously the world has changed since it was introduced, but it is what it is.
Sorry.
