Rekordbox Dynamic Beat Grid Editing Enhancements

When a Dynamic Beat Grid is set, there is no easy way to see where the BPM changes occur.  An indicator on the stripe would be helpful when in Export mode, especially for old school music that was recorded with live drummers.

In addition (and more importantly) once the dynamic beat grid has been set (say after an analysis) there is no way to tweak individual sections without affecting the rest of the grid.  You currently provide a method for adjusting the beat grid to the right of the play head but not to the left.  Ideally when in Export mode you should be able to tweak any section where the BPM is a constant, without affecting any other sections in a dynamic grid (those sections already have a different BPM so your tweak should not apply).

Thanks!

Only if you set it manually would it appear red, otherwise no, there is no indication. The tracks are either analysed as dynamic or normal, there is no "hybrid" mode nor indicators for where the grid is one or the other.

Can I ask why you would need that or what purpose it would serve?

If/when you were playing that track in a sync situation, the tempo of any segment would be adjusted to compensate for any changes, resulting in a consistent tempo playback.

So I did some poking around the backend of Rekordbox and found that the collection can be exported to an XML file.  In that XML file are all of the songs in the collection with all of their grids clearly defined within XML tags.  The breakdown of the XML is contained at the following link http://www.prodjnet.com/rekordbox/support/pdf/xml_format_list.pdf .

The great thing is that it can also be imported as a playlist, so with some creative manipulations of the file you can edit the dynamic grid directly in the XML.  Obviously this is very inefficient but for those old songs that you just have to have gridded there probably isn't a better way than a direct edit of the grid XML (after a dynamic analysis of course).

I will follow up at a later point with some pictures and an example to further elaborate on some useful enhancements I would recommend for the Export function when editing dynamic beat grids.  

To the Rekordbox Team, thanks so much for exposing this!!!! Excellent capability!!

Good thoughtful response.  In performance mode it wouldn't matter especially when sync and good pitch control technique are used. 

It comes into play in the Export mode when you are prepping tracks.  Current music may not require it as much, but older tracks with a human drummer, or newer tracks where tempo changes occur, require a little more work when prepping.  Being able to see where the dynamic tempo changes occur would allow us to clearly see how the analysis did, and easily go to those sections on the stripe that might need some tweaking...

that is assuming that my suggestion about a finer level of beat grid adjustment is implemented, as without that I agree there would be no need for indicators since you couldn't do anything with the indication anyway...

I hope that is clearer now.  

It would be similar to when we had to warp tracks if we wanted to play through long mixes on a tempo changing track (we eliminated the tempo change - by warping and using the warped track).  

In other instances we would find a few bars where the tempo was constant and create a loop to mix into and out of...

with the dynamic grid you do this all for us, so if we had the tools to properly assist the dynamic grid we could do what we used to do by hand on our turntables in the export mode (once instead of every time we use that track), such that in performance mode we could have a tight mix in tracks with changing tempos and do more effects instead of having to ride a pitch.

I often see on dynamic analysis that the RED marker is not set as the start.  Sometimes the red line is for example the 3rd bar.  Result: the beatcounter (1.1/1.2/1.3 ...) is not counting correct to where you start.  Problem is, if you want to set the red marker manually on the actual first beat, the whole dynamic analysed grid shifts and you can start setting it manually (even though dynamic analysis did it's job great).

Not sure if this helps but I find that as long as the Dynamic Grid analysis has accurately set the beat grid, then the first few beats are detectable when quantization is selected, thus you can snap the red beat counter to the appropriate "1.1" as long as you are within the first bar.

Songs with a Drum roll intro often have the 1.1 beat set incorrectly when I do a Dynamic analysis, but I can easily snap to the appropriate 1.1 (when Quant is on) and then set the RED marker accordingly.

If Quantization is not set then yes where you set the 1.1 does throw off the rest of the grid, because you are now moving the beat grid to your newly selected 1.1. Which isn't on a detected beat.  

In those cases my request at the beginning of the topic is the solution.  First you adjust the intro of the dynamically gridded track without affecting the rest of the track's grid (getting the BPM for that section correctly adjusted for each of the beats). Once the beats in that section are correctly set, you can then snap to (Quant On), or manually select (Quant off) the place to set your 1.1 beat.

Anyway that's how I would use a beat gridding enhancement.  On a side note I would also like to be able to set the 1.1 anywhere in the track I like, and anything to the left of it would show as a negative -x.x bars, to the right the bar count would go as normal.
