I tried to analyze a particularly critical track, which another user had already used (Title: Tribal Tekto, Artist: Area). Even with the new version 1.6, the BPM variation zone between the 4:10 and 5:07 positions is not detected. I managed to fix the grid using the “anchor” as it was already possible to do with the 1.5: it was a big job, but it is possible to do it. But the exact same job was done with 1.5, so honestly I don’t understand the difference between 1.5 and 1.6, because the anchor placement system, the BPM modification, etc. seems to me the same.
I also watched the videos on youtube, but I don’t understand what the improvement made with 1.6 compared to 1.5 with regards to the flexible grid consists.
