I'm pretty new to Essentia but am quite impressed with it. There's one feature that I'm hoping someone can help me figure out (if it's even possible). Using RhythmExtractor2013 I can get the times of all beats in the song, and it's quite accurate. Is there any way, though, to find which beats are the first in each measure? e.g. beat 1 of a measure in 4/4 time.

Thanks! Keep up the great work.
