Okay, so the "issue" is that they actually changed the spec:
Hi,
Just upgraded from a ddi rx to an rz.
Before, my waves were in perfectly aligned before but now, no matter that they are beat matched via audio and with the bpm counter, the waves drift horribly.
Im using:
RB 4.4
MacBook Pro (15-inch, Late 2016)
processor 2.6 GHz Intel Core i7
16 GB 2133 MHz LPDDR3
As I mentioned, this just happened with the RZ. The RX didn't have any of these issues.
All tracks were analyzed in normal mode and the pitch range in are the same for both decks at +/- 6%, master tempo wasn't engaged.
Okay, so the "issue" is that they actually changed the spec:
Post is closed for comments.
This is perfectly normal when you don't have SYNC enabled as the waveform doesn't stretch. You'll see they align at the middle, but as deck 1 is at +5.5%, and deck 2 is at -2.4% (a difference of 7.9%), the upper waveform will be moving 7.9% faster than the bottom, with the beats aligned at the middle (play head). If you had both tracks at zero percent, they would both run at the same speed, but they wouldn't be at the same tempo as the distance between beat markers would be uneven due to the difference in track tempo.
Update.
Even with sync, the tracks do not align:
If I remember correctly, when I moved the tempo slider, the track's wave decreased / increased in size accordingly. Now that doesn´t happen anymore.
Is it something to do with the RZ?
Thoughts?

Sorry guys, the reason (as mentioned above) that this did happen was when the sync was not enabled, but I've passed this along to the engineers to investigate. Thanks for your patience.
Version 4.3.1 doesn't have this problem. I'm using DVS with Mac OS 10.12.6 and a DJM-450 with sync disabled. Disabling DVS fixes the issue, but I need it in my setup.
You can get 4.3.1 from:

im getting the drift, on a ddj rz very annoying
We have a ticket open with our rekordbox team, but as they're currently working on rekordbox 5, it may take a bit.
I'm having the same fault ? please try this - go to setting and change track analysis to dynamic
@Pulse:
it works!
Thx for that!
Glad to hear it - thanks for writing back.
Having the same issue as reported earlier.
This happens in anything past 4.3.1
Looking forward to resolution for now staying with 4.3.1
@DJDenverb > See the official response above; this is a change in spec.
wait what?
Did something change? Last we heard it was getting past to engineering.
The answer is "this is by design"? I am just trying to understand my options. Is it I can either have DVS disabled and the software work correctly.
or
I can enable DVS and it stretches out like it does? If that was done on purpose I don't follow. I can have two tracks identical in bpm and directly on beat and they will now drift without me touching anything. How is that an improvement? Am I missing what you mean?
I have tried with beta and its same. 4.3.1 works 100%, it is accurate and stable
