M Mods

M mods are one of three types of speed mods in StepMania, the other two being X mods and C mods.

This speed mod was introduced in OpenITG (it is not available in StepMania 3.95) and is available in SM5 too.

The M stands for "maximum" and this mod calculates an X mod for you based on the BPM that you set. For example, a speed mod of M550 will calculate an X mod where the maximum speed is 550 BPM. Just like X mods, these mods do not eliminate BPM changes or stops, and will not disqualify from ranking in ITG.
