XDJ-XZ beatgrid explaination

I have recently purchased the XDJ-XZ. However, the beatgrid doesn't seem to quite make sense. Even when the beats are matched, they still look as though they are out of phase, until they pass under the playhead, at which point they look synched up. This is in contrast to rekordbox, where the beats look in/out of phase all of the time, and it's really confusing.

Is there a way to change this?

Think of it this way...

When you have one track playing, it just plays along at whatever speed - if it's 0%, it plays at its native speed, but if you pitch it up 10%, it moves 10% faster. Likewise to having two tracks playing, one at 0%, and one at 10% (to match the first); the one that's pitched is not stretching the entire waveform, it's simply moving 10% faster than its base speed, but because they're matched in TEMPO, those beats will align at the play head (the mid point of the screen). This means you'll see the grid for that pitched track moving faster, but still matching at the mid point.

When you SYNC, the master track serves as the target, and the slave stretches the entire grid to match that target grid size. The waveforms march along in a matched stretched display.

And no, without sync, there is no way to stretch the waveforms to match, it just speeds them up or slows them down.

Are you checking the Beat Grids in rekordbox when you analyze your tracks? Might be off slightly, so check there first.

Hi Jay, thanks for getting back to me. I can confirm that the grids in Rekordbox are definitely correct.

The issue isn’t with individual tracks per se, but when two tracks are playing together, the grids aren’t lined up, even when playing at the same tempo, until the grid passes directly under the play head, even though the beat match is definitely good. This causes problems because it makes it difficult to jog the track correctly whilst playing.

Any thoughts?

Cheers!

Hi Pulse, okay great that makes sense, it's good to be able to put words to what I am seeing. However, this runs contrary to my experience when using rekordbox. When using rekordbox, pitching up and down doesn't seem to just adjust at the play head, the phase of the song will change along the length of the grid, and so I am easily able to jog the track in order to bring it back in sync, I am having difficulty replicating this functionality on the XZ.

@Louis > If you disabled this checkbox in rekordbox you'd see the same behaviour:

@Pulse - Yes that looks like exactly what I am experiencing. Do you know if there is any way to adjust this functionality on the XZ?

Unfortunately not.

This is disappointing. I reported this bug when DVS came out with Rekordbox DJ and then with the next update, Pioneer provided the option that Pulse displayed above. Doesn't make intuitive sense with the box unchecked. In fact, every other DJ software (Serato, Virtual DJ, Traktor) all behave the 'correct' way. Rekordbox DJ also behaves correctly but when DVS is not used. Not sure why they're deviating from this with the XDJ-XZ.

It's not "deviating" when that is the core function.

@Pulse - Does Pioneer have anywhere where I can submit a software RFC or feature request?

@Pulse - what I mean is that the standard behavior in Rekordbox (and every other DJ software with waveforms) is similar to the DVS screen checked. Why change this behavior on this unit when it's clearly more confusing and illogical. Happy to post a video in Rekordbox vs XDJ-XZ showing the difference in waveform stacking.

@DJ Chase - I do agree with you on this, it really confuses me too. It would be good if you could post a video, as my XZ is currently being replaced due a jogwheel issue, so it would be good to have an example for us all to see. It’s also reassuring to know that I am not the only person who finds this functionality frustrating.

The display of a waveform moving at the appropriate speed is easier to render than a waveform stretched out by an arbitrary value. When it's matched to another (in the case of a sync), it's easier to display because the system can guarantee it's not trying to stretch two waveforms.

After spending a few more days playing with it, it doesn't seem to be an issue. I noticed the unit changes the stretching occasionally as part of its rendering but doesn't affect usability of the unit. I don't expect it to have the processing power of a laptop grade CPU in rendering a smooth waveform and stretches and compresses with changes in the tempo slider.

I do hope that pioneer launches a new line of products with an improved processor and screen. The displays on the all the units seem to be a much lower frame rate than the competition, but guessing that will come with the next line of products!

Thanks
