Hi-speed is a multiplier to the speed at which a note is falling, relative to the normal measure height in rhythm-matching games. In O2Jam, the normal measure height is 400 pixels.

Beginners must note that hi-speed does not increase or decrease the rate at which the song is played. The song will neither be played faster nor slower, instead the notes will fall down quicker or slower. The higher the hi-speed, the notes will fall at a faster rate and the notes will be further apart as well. At lower speeds, the notes are generally packed closely together, as opposed to the big gaps among the notes at higher speeds.


Originally, the options of hi-speed in O2Jam are:

  • X0.5
  • X1 (normal height)
  • X1.5
  • X2
  • X2.5
  • X3
  • X4
  • X5
  • X6
  • X8


In some countries, the X8 hi-speed is replaced by the XR (or RX) hi-speed, which randomly assigns a different hi-speed for each column in the notechart.
