Questions about Pioneer DJ DDJ-FLX4

Hello, I can't connect Serato Lite 3.2.0 with the FLX4 with my Mc Book Pro 10.14.6 (Mojave). I get a message on Serato Lite: 'Pioneer DDJ-FLX4 hardware connecting. This can take up to one minute.' and then : 'Pioneer DDJ-FLX4 hardware failed to connect. Please try again.' and a green midi led flashing on my FLX4. I updated the firmware on the FLX4, tried the Mojave-compatible Serato 2.5.7 version, and used the usb cable supplied to connect the FLX4 and the MAC. No luck. Does anyone have any ideas? THANK YOU!

Hi... Can the speakers from a simple mini stereo system simply be connected here? If I remember correctly, these are inserted into the speakers and the system via the wires at the end of the cable. Does it work the same way with this DJ controller?

No Bluetooth for Bluetooth speakers, correct?

What do you use to output the sound? Speakers, Bluetooth speakers, soundbar?

Hi, can you also scratch with it? Lg

Hello together How exactly do you start with it if you have no idea about it? Can I use Mp3 from the PC? Thanks for your feedback.

Can someone tell me what I need to connect the DJ controller to KRK Rokit RP7 G4 speakers? Is that even possible?

The part is not yet available, but already has 5 reviews?

I ordered this product DDJ FLX4 since January 5th for a delivery on January 31st and hop the date is postponed for February 28th! And the price drops to 312 instead of 321CHF. What does all this mean? Can you refund the difference? And confirm the delivery date? Where are you with the supplier?
