Topic: Help Improve FLUID Beatgrid – Share Problematic Tracks
Hi everyone,
I’m opening this thread to collect tracks where we're experiencing issues with FLUID Beatgrid.
The objective is to gather clear, real-world examples that can help identify patterns, reproduce problems, and ultimately improve the accuracy and reliability of this already amazing and game changing feature❤️

[Please do NOT upload any audio files.

Instead, share the exact track details so the issues can be properly identified:

Artist
Track title
Remix / Edit / Version (if applicable)

If useful, you can also briefly describe the issue (e.g. drifting grid, wrong BPM detection, incorrect transitions between sections, etc.).
The more precise and consistent the input, the more helpful this will be for the dev team.
Thanks in advance to everyone contributing.

My first two tracks

1) Major Harris - Love won't let me wait
2) The O'Jays - Love train

For both fluid Beatgrid fails to identify proper bom, phrases, downbeat and grid.
 
What you have to bear in mind is that the detection system assumes everything is 4/4

The further back you go, the more common it is to find sections of other time signatures in tracks.

For example Bee Gees "Jive Talkin'" has small sections of 3/4 (the diddle-iddle-ee instrumental riff).

Sailor "Glass Of Champagne" has brief sections of 2/4 throughout.

Detroit Spinners "Ghetto Child" small sections of 3/4
 
Both of mine are 4/4...
 
I know - I didn't say they weren't. I'm giving examples.
 
Yeah got it 😅
 
I've just sat through all 6 minutes of Love Train with the metronome on, and can't see or hear any issues. 🤷‍♂️
 
Diana Ross - Upside Down has sections of 2/4

I tried to make on 8 bar automatic loop of the first 8 bars...I had to make it manual...
 
Did you try to lock the grid first?

This may well be a separate issue though, because a loop should ideally follow the bar/beat variations well enough to cope when a variation falls within a looped area.

I just discovered how to move grid bars reading the other post 😅
A walk trough is soooo necessary
 
I noticed earlier that the VDJ manual has not been updated yet. I'm sure it'll come. 🙂
 
Here is a Soca song that has a lot of live drummer soloing throughout (snare rolls, kick drum rolls, other rolls, etc, a la Aric Improta style) that seems to throw off the scanner once the the solos get more intense later in the song

Ricardo Drue - Happy Music

Please note - the song is 4/4 timing with a fairly stable BPM roughly (just an estimation) within the 122 - 128 range even with all of soloing, and the artist + the rest of the beat is still performing as normal throughout, it's just that the drummer seems to have more of a lead instrumental-wise.

(Also, to be fair, this song also is improperly gridded in DJay Pro as well once the solos get more intense - I tested with the latest version of time of writing (= v5.6.4))

@devs Please message if you need the song.
 
Oh yeah that does look a bit crazy. I assume you left the range on 60-180? Did you try narrowing the range?

It does baffle me why on a track that's c125 the analysis believes single beats are 138.7 or 113.4

[listens] Hmm lots of snare fills on offbeats. The algorithm doesn't like those! I've found the same on jazzy offbeat stuff. There seems to be a regular kick though, so why is it not paying more attention to the kick?

[tries with range at 122-129] I have to question why, when the range is reduced, the result still displays tempos way outside that range for single beats. Why does it "break the rules"?

[later] just switched to rigid and it's a regular 125 all the way through....

 
It's a beat where the drummer has some slight swing on the notes (you could probably imitate that in a DAW - REAPER has a random swing setting in the MIDI editor for that). And it does somewhat increase a little in speed as the song goes through (it scanned as straight but you can see it is a somewhat slightly off later on in the song, which is what caused me to switch it to Fluid to see (and get that odd result you see).
