In the TD-25, you can reassign the MIDI note numbers for each of the pads if desired. This can be convenient for MIDI sequencing or when triggering the sounds in an external MIDI module or the computer. From the factory, the MIDI notes are already conveniently assigned. Here's how to change them:
1. Press the function 3[F3] button (MENU).
2. Press F3 (SETUP).
3. Press F3 repeatedly to select "Pad Note Number."
4. Press the KICK (ENTER) button - It will be flashing.
5. Hit the pad - or portion of the pad (head or rim)- that you'd like to set the MIDI Note Number for.
6. Turn the INSTRUMENT knob to choose the desired Note Number.
7. Repeat Steps 5 and 6 for any remaining pads.
8. Press F1(EXIT) 3 times when you're finished. The new assignments are saved automatically.
