Diy midi controllor

Hi I am building my own midi mixer controller and I would like to display the deck tempos on 4 digit serial displays like these:

I have searched the forums and found a lot about getting the track name and length to lcds through traktors dennon hc4500 support which does have the tempo on the units lcd so is there a way to get the individual tempos and if so would it work with 4 decks?


Cheers

What are you using as the brain for your midi controller? You could use MIDI clock out and some calculation rule to calculate the tempo (BPM) of the track and display it the display.. I know this is possible for the master tempo, but I don't know if it's possible for each deck tempo...
