DN-S3700 & Serato Dj Pro


hey guys, for the past 2 years I’m working with MCX8000 & MBP (early 2011, os x 10.9.5). now I want to get my old gear (2 DN-S3700 & Rane TTM57SL) to be an alternative setup fot different gigs - is possible to get everything working with Serato Dj Pro?

Also another question, probably it’s because some update I had during the last 2 years - but when I connect the 3700s thru my SL4 and a usb to the computer, on hybrid midi mode - the 3700 seems to not have any MIDI control over the Serato Dj Pro - how can I fix that too?
