Reply to Sync button on software with cdj question!

It's been years since i matched a beat with cdj's, i haven't touched cdj's in around 6 years until the other day when I couldn't for the life of me match the beat by ear.

About 3 years ago i started mixing with Virtual DJ and haven't needed to beat match by ear since then which I'm not proud of. I know I can practice and get back the ability to match the beat by ear again.

What I'm wanting to know though, is there any software like Virtual DJ that will allow me to sync two tracks by pushing sync but the two tracks are on cdj's and not from my library of tracks on the computer.

Or vice versa, can i play music from the software and use a cdj as a controller but always use the sync button on the software

I hope this makes sense and I know I should really learn to beatmatch by ear again, but I would love to know if this can be done.

Thanks in advance.
Aaron.
