Reply to MIDI (or HID?) Mapping? (I know...)

I'll start by saying I obviously don't know the first thing about mapping...

In the video in this thread: http://www.djranking s.com/community /showthread.php?t=33996 , this guy has his FX LEDs blinking. I thought when you use the S4 in Midi mode, you lose the beat counter number displays, which still work for him. So has he done some sort of mapping in HID mode?

I would like to be able to create a mapping where, say, the active FX buttons are solid on, and the inactive ones blink, instead of just being off. I do not want to lose my beat counter number displays though. How do I achieve this?
Thanks!
