interface 2 rekordbox dvs and 4 decks

You'll have to set deck 1 and 2 to relative or absolute mode and the IF2 as default audio interface 

Then use deck 3 & 4 in internal mode. It will however mean that you will need to control them from your computer. Or use a MIDI controller to control them with hardware. 

This doesnt happen . When i use interface 2  , rekordbox dont let me use any of internal mixer.Also it doesnt let me  use decks 3 and 4 to output them on deck 1 and 2 . While i am using IF2 decks 3 and 4 are dead .  As an output this is the idiot thing here , it let me use deck  1 and deck 2 and if i want the tiny sampler deck to output it at deck 1 or deck 2  but doesnt let me output deck 3 to deck 1 and deck 4 to deck 2 . Any opinion out there  how to use those  precious decks 3 and 4  extra to decks 1 and 2? This  shit  makes really better traktor and virtual dj .. :( 

Sorry it wasn't useful.

Just realised, I tried this on an external soundcard but it was a 4 channel one. I'll try and see if I can borrow a 2 channel external one from a friend and test it myself in case Pioneer DJ hasn't responded yet. 

This is the point . There no meaning to do that with other audio interface except Interface2 , because only interface 2 give you  the rekordbox Dvs as a sound card .    You can use the  4 decks with other sound cards....But my theme is with  interface 2 , while i am using the Dvs option  to use the 2 more decks  ( deck 3 and deck 4 )
