Rekordbox DJ whit more then one controller

Do you mean 2 controllers plugged into the same computer?  If so, no that isn't a thing that would work with the software because of the way it is mapped and reads the signal pathway for a controller.  No DJ sw that I know of can do this...

yes that exactly what I mean. I have XDJ-Aero and XDJ-SP1 and I can use both at the same time with Mixvibes Cross and Traktor also and when I used Virtual DJ I could also have several midi controllers working at the same time.

I know that XDJ-SP1 is not officially supported by PioneerDJ but it works perfectly with my little hack just not when Aero also is connected, then only the first connected one will work.

But the XDJ-SP1 would be perfect together with controllers that lack some buttons or together with 2 CDJ's 

Can rekordbox dj have a split on the cross fader when you mixing 

Could you give me instructions on your hack to get the sp1 working on  rekordbox i have tried to find the midi .csv files for a ddj sx and ddj sp1 but cant locate them.

Apologies for my lack of knowledge.

I have 2 cdj 400s and am going to try and run all 3

@Gulli > Yes, you CAN use two different controllers at the same time - I've used a DDJ-SX and DDJ-SX2 simultaneously. The tricky thing is both controllers will allow hardware control, so you have to know what you're doing and how you have the audio configured.

@Phil > Sorry, any posts on "hacking" the SP1 into working will be removed as we can't provide support for software that has been modified. Pioneer does not encourage users to modify or alter the code.

@DJ EFO > I'm sorry, I'm not sure I understand what you mean by "split" ?

Can rekordbox dj have a slicer on the cross fader to separate  mixtape into many tracks, like virtual dj

You asked this in another question and I asked what the usefulness of that would be for someone like a scratch DJ who cuts the crossfader quite often, as it would result in chopping the mix into a thousand separate tracks.

Take the recording into an editing software, drop markers, split it as necessary.

It can be something that you can set when you are doing mix not when you are scratch am just asking if you guys can add that features in  future 

Thank you very much for your fast response 

@Pulse can you explain how you do it to use 2 controllers with Rekordbox?

This is my post, please check it.

@DJ-AS > I saw it but haven't had time to create a guide for it; please don't multi-post.

@Pulse

When you say I can use 2 different controllers at the same time, does it means that I can use a DDJ-400 and a DDJ-1000 at the same time on the same pc? Like if I want to mix with a partner and we both know what we’re doing, could it work?
