Digitakt/ Overbridge SYNC with Pioneer/Recordbox Hybrid Set UP

Hello everyone

i have a full hardware set up but also happen to dj, I would like to make a hybrid set up with digitakt and dj mix. I recently bought the DDJ FLX6 to have 4 tracks on my dj sets and thought it was the moment to try this hybrid set up but I just disovered that the controler had not any audio input (except from a mic input which is not assignable to a deck)

I was thinking that with OVERBRIDGE i could maybe get virtually the digitakt with one of the tracks but i couldnt make it. it may exist a way of using Digitakt as the main audio interface but its getting confusing…

I’ve tried to sync with ableton but couldnt make recordbox master of ableton. Only works in the other way ( ableton master , electron slave, recordbox LINK)

and still could not put the digitakt audio track on a pioneer deck which would be the beauty of this set up

I’m thinking of buying an usb midi HUB hoping that it could help recordbox to propose me the virtual inputs of digitakt but not even sure that would solve my problem !

what do you think, what would be the better way for doing this ?
( i know upper models of pionner controler could make it but are really expansive, other wise the native traktor s4 mk2 is cheap, has midi din out and audio input but it but is not mappable for recorbox so cannot be used for preparing sets on cdjs
(in addition the joggs and the fwx are better on the pioneer ddj flx)

thank your for your help and sorry for my englis
