That would be very helpful for me! For about 95% of my music, djay does an amazing job of automatically creating usable beatgrids (sometimes I have to edit BPM or set the grid start but that’s fine). In some cases, though, I will never be able to get the beat grid correctly. The most recent example of where I ran across this is the “Savage (Remix)” from Megan Thee Stallion & Beyoncé. After the first chorus (around 1:20), the beat suddenly “shifts” and then I’m left with an unaligned beat grid so I can choose to either have it correct in the beginning or after this.
This is really nicely visible in the new Neural Mix 3-pane. Over only four bars, the beat grid becomes unaligned and is then just lost.
The same thing applies to songs where the BPM changes drastically, of course.
