@Maicon > No, you can't get the RB to become a "4 deck" controller by mapping the SYNC button as the controllers which feature 4 decks have 2 layers of MIDI signal being sent; one for each "deck." So the play/pause button on an RR sends a different MIDI signal depending on the deck it's controlling, whereas the RB only sends 1 MIDI signal out from that button, even if you used another button on the hardware to tell rekordbox that side of the controller should now be manipulating a different deck in the software.
Yes, you can re-map the Slicer pads to be Beat Loop pads; just delete those Slicer functions in the MIDI editor, then add & learn for the Beat Loop.
Yes, you can disable the quantize for the hot cue - go into the Preferences > Controller > Others and change the setting:
