When I open Scratch Live and turn my mac, then plug in the usb hub which has my cdj connected, the sl3 is directly plugged into the mac and I turn on the cdjs and mixer, sl3, etc. And then I hit the usb button so I can choose Left or Right, the screen does not always give me that option, it will just be blanked. I will eventually get it by turn stuff off and on and reconnect hub, etc, just playing with every thing until I get it.

How can I consistently get Native Control? Am I not turning stuff on in the right order? Could it be my usb be hub?


What am I doing wrong?

Note: One of my cdjs are at ver. 1.30 and the other is 1.33...does that matter....

Hi Rodbo.

I'd make sure the firmware for both CDJs is updated.

I'd also look at getting a better USB hub. It sounds like the hub you have isn't providing enough power or throughput. You may need to test this, cheap USB hubs can cause issues with some devices, although it is hard to tell which ones are good since all hub companies don't promote how they operate... :-(
Maybe go into a computer store with your gear and ask to do an experiment.

I'd make sure you are doing all of these tweaks to make sure your system is optimized for audio use:
* Always plug directly into the computer’s USB port, not a hub.
* Check that you are using a ‘good’ USB port. If you are using a Macbook Pro, this can be the left port or for models with two USB ports on the left and Macbooks this will be the port furthest away from the screen. Try all ports until you get the best results.
* Go to your laptop manufacturer's website to check if there any driver updates for your machine.
* Switch off Bluetooth, wireless network and unplug any wired network connections.
* Switch off screen saver and set sleep mode and hard drive sleep to 'never'.
* Ensure you have ample room left on your hard drive (this is approx 10% of your hard - both internal and external).
* Close down any other software, including antivirus software or the like.

Version 1.30 is the latest that I found available. The other cdj with v1.33 is the what it came with. I don't know where I can find another version 1.33 but 1.30 is whats available on pioneer site.

I might try to use a different usb hub. I have a mbpro 13inch so I only have 2 usb ports on the left. So I have to use a usb hub and my pro is alway up to date.

Do I have to have wireless off when I use serato? No other sw is running and I don't have antivirus (using mac).

Yes - wireless can cause audio interrupts, or connection issues.

As for the firmware, if that's the latest downloadable that may be ok. However, I'd suggest getting in touch with Pioneer about this.

As for the hub, this sounds like it'd be the best, if the 400s aren't connecting properly, then something is throttling their throughput.
