Talk:I Want You Back

THAT ONE BAR at twice the BPM

In the Disney's RAVE version, bar 27 (around the 1:06~1:07 mark) is actually at "twice" the BPM, to make the half beat of the song on that part. It can be noticed during gameplay by looking at the flashing arrows.
Why do I put it in quotes? Because, once converted to .SM, the chart has SO MANY BPM changes that to say "twice" is a problem, haha. The BPM at that bar is 189.474.

• But here's the thing
  all three Dancing Stage feat. games use time signatures; they're found alongside the tempo data
  the "189.474BPM" part is just 94.737 in 2/4
  the available converter to .sm just has taking them in consideration disabled by default since it screws with the arrow positions
  in a similiar way, SEXY PLANET has a 5/4 measure in TKD and the unused TORIDGE & LISBAH in DCT has its first half entirely in 3/4

  • Where did you find about the time signatures? The SEQ*.bin aren't precisely readable... EDIT: Then how do you explain the arrows flashing at twice the speed on that bar? See HERE, at the "na na na na" part--Wanny (talk) 19:04, 21 May 2023 (UTC)
  • The tempo data is not stored in the SEQ*.bin files but rather in the TTB*.bin files
    Upon aligning them 4 bytes per row on a hex editor, the first byte on the left will always be the number of beats on a measure. Most of the times it's 4, but in these two songs, there is exactly one measure in which it is set to 2
    The speed divergence is probably related to the animation only detecting the beginning and the end of a measure, completely ignoring the number of beats it contains
