Speed Modifiers, also known as HS x(a).(b) (with a being a number from 0 to 8, and b being a decimal number, such as 25 or 5) (HS standing for High Speed), are modifiers that affect the scroll speed of the arrows of a chart. They multiply the BPM of the current section of the song by the modifier you select. They were first introduced in DDRMAX. The original Speed Modifiers were x1, x1.5, x2, x3, x5 and x8. In DDR X, the x0.25, x0.5, x2.5, x3.5, x4, x4.5, x5.5, x6, x6.5, x7, and x,7.5 speeds were added. In DDR X2, the x0.25 and the x0.5 speeds were removed.
In DDR X2, at the beginning of a song, you can press the left and/or right buttons to change the current speed modifier by 0.5.
If you are unsure as to what speed modifier to use for a song, take the main BPM of the song (e.g. Elemental Creation's main BPM is 424, while its actual BPM is 106-424) and divide 510 by the main BPM. If you're unsure as to what the main BPM of a song is (if it has BPM changes), then the BPM that is used for the majority of the song (e.g. Elemental Creation's 424 BPM) will be the main BPM.
$ v=510/b $ (v is the calculated value, and b the song's main BPM)
$ v=510/424 $
One of the speed modifiers closest to that value (e.g. v 1.20283) will be used. In this case, x1.0 is closer to 1.20283 than x1.5 is close to 1.20283, so it is recommended to use x1.0 for Elemental Creation.

DDR Wii SeriesEdit
Speed modifiers were not introduced until DanceDanceRevolution HOTTEST PARTY 2. Just like with pre-DDR SuperNOVA arcade games, only x1.0, x1.5, x2.0, x3.0, x5.0, and x8.0 are selectable. In later Wii DDR games, the options are: x1.0, x1.5, x2.0, x2.5, x3.0, x3.5, x4.0, x4.5, x5.0, x5.5, x6.0, x6.5, x7.0, x7.5, and x8.0. In DDR II, x? is a selectable speed modifier. It gives a random speed modifier from the 15 selectable options (x1.0, x2.0, x3.5, etc.).
- Although the arrows appear to move faster/slower, they reach the step zone at the same time as 1x.
- If the Wave option is used, the current speed modifier will be dispelled and set to 1x.
