Forum: VirtualDJ Technical Support

Regarding the sync issue, you are using pitchQuality 2 or higher?

Regarding the grayed Beat, i get the same behavior in both Rekordbox and Serato, so most likely it's a firmware/hardware issue.

I can't say for XDJ-XZ. I don't have the unit. But for DDJ-1000 it has been said many times allready:
It uses on board effects for analog sources and software effects for digital sources. And there's nothing you can do to change that. It's how the device firmware is programmed to operate.
Even with Rekordbox DJ, the effects for digital (USB) channels are provided by software, while the effects for analog inputs are provided by the device.

Some more technical stuff:
The original firmware of the device (DDJ-1000) had FX send/return channels on the USB bus.
That was in order to use software effects even for analog inputs as soon as a DJ software was connected to the board. However that implementation had some issues.
We don't know what issues exactly. We only know that it was possible from time to time that send/return channels would not operate.
Anyway Pioneer in order to fix that issue updated the firmware and removed FX send/return channels from USB audio bus. Also now the firmware is set so that hardware effects are always used for analog inputs regardless if a DJ software is connected or not.
To make it even more strange, switching the FX selector to an analog source won't automatically switch the FX unit to hardware when a DJ software is connected. Instead the firmware must also sense audio signal present on that channel.
And this becomes even more strange when you set the FX unit on the "MASTER" channel.

Anyway.. DDJ-1000 is a different controller than XDJ-XZ and honestly after working with litteraly hundreds of controllers the two most valuable advices I can give you are:
1) Don't expect one controller to behave internally the same way as another. Even if it's a MKII model (like DDJ-SZ vs DDJ-SZ2)
2) Pioneer XDJ series is a mediocre series of gear.
XDJ-1000 = A stripped down version of CDJ-2000NXS plagued with several issues even as a stand alone device.
XDJ-SX = A mediocre stand alone controller with MIDI capabilities that wouldn't excel neither as a stand alone device or as a MIDI controller.
I can keep on with almost all the products of this series.
That's not an "official" statement of course, rather than a personal opinion, but if you want to get the most out of your gear with Pioneer either get CDJ or DDJ series. XDJ series for Pioneer is something like eXperimental series. Which means that all the gear in this series have their own twirks.

PS: I do understand your frustration about XDJ-XZ. I'm just not the right person to give you more help about it since I don't have nor I ever used the device.

As I said, I do understand your issue.
I don't have the controller so I can't really test what's the cause of your issue.
Technically it appears that channels 1+2 from the USB audio bus have some delay (since you need to speedup deck 1 to bring it in sync with deck 2)
This can be a drivers issue, a computer specific issue, a windows sound settings issue, or anything in between.
It's clearly not a direct VirtualDJ issue (as VirtualDJ as you said works fine with all other controllers)

I asked you a couple of things above.
The reason is that I'm trying to understand if there's a chance something introduces a delay on channels 1+2 but not on others.
Theoretically, if you DO use the ASIO drivers then Windows stop taking part into the communication between VirtualDJ and the soundcard of the device.
If you DON'T use the ASIO drivers then there's a chance Windows introduce a delay because they try to apply "enhancements" on your sound (and they usually do so only on chans 1+2 of sound interfaces which are considered the "main" channels)

So, take a moment to check and answer my questions above. I'm trying to help here.
