This option sets the upper and lower limits of the BPM range while analyzing files. Selecting the correct range will help to avoid half or double BPM values being calculated when using Set Beatgrid/ BPM. For example, if you have tracks that are being analyzed at 140 BPM and you want them analyzed at 70, choose 68-135.
NOTE: If you find tracks with BPM values that are incorrect, check the BPM Range is correct in the Offline Player.
