DJuced missreads the BPM of some of my tracks. For example it says that the BPM of 'Current Value - Dark Rain' is 107, which is not right -since it's a very fast dnb track. it is really annoying because i want to use certain tracks but i can't see their true bpm. Why is that?
Song analysis can never be perfect, specially if the song has multiple section of different tempo. In this case, it is sometimes necessary to correct the beatgrid manually, as explained in this tutorial video:
Djuced calculates one BPM for the full track, so if the track has not a constant BPM, you must re-edit the beatgrid with the process described in the video listed by Phatso. "Current Value - Dark Rain" slow intro is over1 minute long, and afterwards the BPM is faster in the next 3 minutes, so it is normal DJuced does not know the BPM of this tempo-changing track.
