Excelente, smart fader is amazing!!

I prefer djay pro ai over rekordbox, the user interface is better and it’s more efficient on Mac I think. But I have a FLX 4 and rekordbox use the controller better than djay pro.

This is a good move in the right way but, i dont go back to djay until smart colors and beat fx are compatible, its close, i waitting with hope.

Thanks for the work guys.


Scooped up the flx4 for the heck of it today.

Is 3.0 the one i go ahead and get @Michael_Wisniewski?

Anything missing from it function wise?

Yes, 3.0 is the one. It’s not perfect but it’s pretty robust.

I cant seem to get the manual fx to work correctly when it comes to the “fx select” button. I have it mapped for deck one when i press it , it cycles through the fx menu for manual fx in djay. But for deck two i cant figure it out. I mapped fx1 for deck two to the on/off blinker button but the fx select for deck two wont map to -deck 2 fx 1 select next.

It works if i map it to the “beat” button but cant get it to the fx select

Any clue? @Michael_Wisniewski

Yup, here’s an update to version 3.1.

  • BEAT FX Deck Selector - now selects Deck 1 or 2 (the option to select 1&2 does not work, it does not send a MIDI command).
  • FX SELECT button cycles through FX on selected deck. SHIFT+FX SELECT cycles in reverse.
  • BEAT arrows adjust main FX parameter. SHIFT+RIGHT arrow = BPM Tap. SHIFT+LEFT arrow = Restores Analyzed BPM and Grid
  • LEVEL/DEPTH knob adjusts Dry/Wet
  • ON/OFF button - toggles FX for selected Deck
  • SHIFT+ON/OFF - toggles Neural Mix/EQ for selected Deck

MIDI commands for the BEAT FX Deck Selector 1 & 2


Heck yeah! Definitely appreciate it!

I had been at it all morning trying to figure it out.

I shall update it right now. Its been a fun lil controller to mess with on the fly.

Thank you so much for this mapping it’s fantastic!

I remapped SHIFT+Smart CFX to toggle previous crossfader fx
And SHIFT+ Smart fader to toggle next crossfader fx

Works like a treat with your new version
