Analyzing tracks with "No Markers" vs selecting "Only Grid Marker" downbeat outcome question

John6

I noticed when Async-ing / Analyzing tracks with "No Markers" selected (in Preferences / Automatic Options) vs selecting "Only Grid Marker" gives VERY different Grid results.

I assume using "No Markers" avoids using Traktors algo to find downbeat and instead relies on BMP? 

Maybe someone can confirm this?

Thanks

Anyone at all? Thanks

Make screenshots of the VERY different Grid results and post them here.

Async / Analyze using No Marker chosen from Drop Down Box (Preferences / Analyze Options)

Async / Analyze using Only Grid Marker chosen from Drop Down Box (Preferences / Analyze Options)

Only Grid Marker produced the correct downbeat result

No Marker Produced a different result (def not the correct Downbeat)

The 'Downbeat' is a gridmarker, so without one you will only see the transients.

You have to manually set your own downbeat (gridmarker) if you forbid Traktor to place one after analysis. After you have set the first downbeat, the rest should follow exactly like the second pic. Unless you place several gridmarkers to make it a 'flexible' beatgrid.

Yes Thanks.

I totally understand how using Analyze with Only Grid Marker checked in preferences works and everything about it. I got that solid.

I asking about (what you call) Transient lines (faint white lines) that Traktor creates using No Marker chosen in preferences after analyzing a track. There is a big difference between the results of using No Markers and Only Grid Markers chosen in preferences analyze options.

Only asking bc I used No Marker while analysing 500 tracks. I set my own Grid Markers based on (what your calling) transients. The results were all over the place.

Im trying to help people who might go down the same road with these options.

I cant seem to find the explanation in TP4 manual

Here's what google says

In Traktor Pro 4, "transients" refer to the very first, sharp attack part of a sound, like the initial hit of a drum snare or the pluck of a guitar string; essentially, the momentary burst of audio that occurs at the beginning of a note, which Traktor analyzes to automatically detect the beat and create a beatgrid for accurate syncing between tracks during DJ mixing. Key points about transients in Traktor:

• Beat detection:Traktor uses the transient information to identify the beat positions within a track, allowing for precise beatmatching and loop creation. 
• Analysis process:When you import a track into Traktor, it automatically analyzes the audio to locate these transient points. 
• Visual representation:You can often see these transients represented as vertical lines on the waveform display in Traktor, indicating the start of each beat.

Is there a solid explanation on what criteria Traktor uses to set (what your calling) transients after analysis using No Marker option ? (Preferences / Analyze Options).

Thanks

It's part of the automatic grid detection. The grid will be aligned to the main transients. As long as you don't have at least 1 gridmarker (and you only see the transients) any function relying on quantization (quant, beatjump, certain periodic FX) will not work correctly.
