After previously reporting this here, and seen it also here, I've finally captured it on video.
Today I upgraded to Rekordbox 4.2.5, and was about 30 minutes into recording a set when the tempo randomly jumped up massively. Nothing looked wrong on the interface, until I touched one of the tempo sliders, at which point the tempo in Rekordbox mysteriously changed its value from 10% to WIDE.
I stopped the mix, restart the tracks, and the same thing happened. I've used a crude screen grab tool to capture this. See at 55 seconds in, the pitch changes even though the interface does not.
This is happening on two different computers, both with the most recent version of Rekordbox on.
Any suggestions?

It looks like your beat grids may be off. Did you analyze in normal more or dynamic?
I would play it back in export mode, or remove the track from your deck. Re-analyze it with the tempo range from 85-145.
Hey @Harry J
Thanks for commenting. While the track was already analysed dynamically using a similar tempo, just listening back in Export mode helped me find the problem.
At the end of the track, the treble doubles once the bass drops out leaving that riff which occurs twice per beat:
This seems to confuse Rekordbox into thinking the tempo has massively altered. The beatgrid can be seen changing in the screen grab:
The BPM at the point shown changes from 123.99 to 165.28. I'd missed this because obviously the song doesn't change when you listen to it in isolation.
I just need to figure out how to tell Rekordbox to ignore BPM changes past that point in the track...!
Hi.
I got this sometimes with some tracks too. But this is a missinterpretation of the Beatgrid Analysis. I think it happens with the dynamic Analysis only. The way how I am Fixing it is changing the BPM for the track ending to the regular BMP of the track.
If I see your Screen shot correctly - go to the 'grid' mode in recordbox. Move your track to the last gridmarker before the BMP changes. Now freeze the grid markers before the one you moved to by clicking on
Now type the correct BPM manually in
and hit 'enter'.
It should adjust the BPM only for the grid markers moving Forward and your Problem should go away. To me it happens mostly on track endings while the track is Fading out or has sections without a clear drum line.
But as said - doesn't happen that often. However it is very strange if you are in Transition using sync and quantize on and the unexpected BPM Change kicks in.
Hi @Frank
Thanks very much. Although I worked it out since posting, this is the exact way I've overcome the problem, which has fixed the problem perfectly.
I guess its dangerous to assume that just because the beatgrid is okay to begin with, that it ends that way. It would have been pretty embarrassing if I was being paid thousands to entertain a mass audience (good job I'm not then... :-)
I must be a sign of age when I just assume everything will work as well as my old CDJ1000's...(!)
:-)
you're welcome!
Also, set it to normal analysis and the odd time you have a track with tempo changes, switch to dynamic just for that track and then switch back to normal.
95-99% of my library works with normal mode, at least for BPM. I occasionally have to pick the downbeat but at least the bpm is correct!
That video resolution was so poor I could hardly tell I was looking at rekordbox, sorry. Need a bit better quality to see what's going on.
Hi Pulse
Yeah, YouTube shrunk my video down to 720px from 1920px. Very good of it...
Anyway the issue is sorted, but thanks for checking by.
