I was hoping that maybe because the px850 connects through usb that one can listen to external audio anyway. Instead I'm gonna purchase a separate audio mixer.

It would be better though if Casio could include the "line in" in their flag ship model.

So I'm planning on purchasing the Casio Privia PX 850.

One thing I can't find in the specs though is line in connectivity.

I go to youtube a lot for backing tracks and I also use Audacity which helps with slowing down tunes, looping chord progressions, etc. All this is super easy if I simply hook up the line out from a laptop into the DP's line in. 

Is there a way to do this with the PX850 too?

Thanks!
