I'm currently working on a rhythm game, and have a set of MIDI note events converted from the MP3 file, but I don't know which notes is a beat. Is there any way to detect that?
Here is the MIDI data of mine, have a look:

1, 0, Start_track
1, 0, Tempo, 500000
1, 0, Program_c, 0, 0
1, 0, Note_on_c, 0, 66, 53
1, 3, Note_on_c, 0, 70, 21
1, 4, Note_on_c, 0, 51, 28
1, 14, Note_off_c, 0, 51, 64
