Example with NO dynamic grid (constant BPM for all track):
Instead when I have a track with variable BPM, I had to put anchors to lock the grid in place, I did this with Engine DJ. This is the result:
As you can see in the last track the grid is well aligned with the sound wave, exactly like in the original on Engine DJ.
What I’ve seen is that all tracks that have dynamic grid (i.e. with “Markers” as you call them on Lexicon), it has fine grid. Instead, the tracks with fixed BPM have a shifted grid as I show you in the first track. Not all fixed BPM ones are grid shifted, but many are.
It’s not a graphic effect because when I listen to them if I activate the “metronome” in the player I feel that the grid is actually not aligned like the original one was.
