Ddj sx

Hello everybody!

Im planning to get a DDJ SX but I I'm trying to find out a couple of things about it first.

Besides from using it for djing, I'll use it as a sound card in ableton live.

Can anyone confirm some of the following questions please!?

-Are the channel inputs terminal equal to soundcard inputs?

I mean,
Can I record a mic, a turntable or a line input signal?

-How many outputs it has as a soundcard?

2? 4?

-is it fully mappleable in other softwares than serato?

If yes:

are the pads velocity sensitives if mapped in ableton live?

I can't found this info anywhere, so, someone that already got one, please a little help here!

Thanks in advance!!!
