DDJ-1000 Rekordbox on USB1 + other software on USB2?

Hello,

I'm really close to purchase a DDJ-1000 but I'm not sure if it can be used by 2 different software in the same time:

- deck 1+2, USB1, laptop1 - with Rekordbox

- deck 3+4, USB2, laptop2 - something else (I'm playing also with Djay Pro 2 from Algoriddim for Spotify integration :D )

Algoriddim is advertising the console as compatible (excepting Windows compatibility - I'm using on a MacBook for that, it's fine, and waveforms on jog wheel displays) but I'm not sure if it can play nice along Rekordbox on channels 1 and 2.

Also, when connected to a computer that runs Rekordbox the effects goes software (right?), can those stay hardware for Djay Pro 2 or they are based also on the software mapping as Rekordbox?

Thanks!
