5) Click the SMPTE Signal button to start listening


6) Here is the display if everything works fine

If FPS auto was selected, Auto will appear in red the time required to calculated the effective rate, so up to 1 second. Then it displays the actual rate, e.g. 30. 

As long as the white dot at the bottom keeps running, it means the signal is 100% healthy. 

If the signal is way too weak or there is a problem with the setup: 

If the signal is strong but not consistent, there could be yellow 

(1 or 2 invalid frames in a row) or red dots 

(more than 2 invalid frames in a row)


While listening to the SMPTE signal, make sure to select the next line in the list and click either Slow, Medium or Fast at the right time. This choice means at which speed the prompter will move to the line.

Once you clicked a speed, the current SMPTE time stamp is assigned to the selected line and the next non-empty line is automatically select. 

It is possible to edit the time stamp and change the speed by clicking on it in the list.

If the stamp is orange, it means that there is not enough time since the previous line to move to that line at the selected speed. It will work fine but at a fastest speed.

A red stamp means that the line is set in time before the highest time so far.


Close the Timeline Window and simply click the Sync button.  SONG MUST BE IN THE SETLIST WINDOW IN ORDER TO BE READ BY SMPTE.
