There must be some addnl settings to perform also. When I tried this for button L6, I got a tempo light but when I banked away from that song, the light stopped and did not return for any other song or even the song that I was on when i got it to flash in the first place.Turn on "Flash w/ tempo" and "Update on Preset Change" on the button that you wish to flash. It'll also operate as a tap tempo button.
