Game Module: kbm

This mode will be added around alpha 4.19.0/alpha 5.0.0-pre45-ish of Project OutFox.

About

This mode parses files made in the bmson format, and usually is arranged into a two octave keyboard layout, sporting 24 keys in a piano style layout. This mode also supports 4 octave mode, or 48 keys. It is Highly recommended that this mode is played on a MIDI controller, or if you can find one, an original keyboardmania Playstation 2 controller from the early 2000s

History:

The parser support for the mode (bmson) is currently in development as it requires a new parser system to be initialised and set up for this type of chart.

This mode is not selectable in the game select screen at the moment.

Game play

This mode is played default in down scroll, with the note receptors at the bottom of the screen. The player then hits the piano notes depending on how they fall.

Mechanics

key sounded

The notes in this mode are based off of small clips of audio that react when you press a key. This means buttons you press will add to the song being played. Similarly there can be percussion and other sound effects added to these. Due to the nature of key sounded charts, they take longer to load and compile than other charts, so do not be surprised if you see a ’loading screen’ for be-mu charts!

Play Styles

Grading / Accuracy

Scoring

Health Bar

The “health bar” in this mode is called a ‘gauge’. It is a measure of accuracy as well as your ’life’. Depending on the difficulty you need to achieve a specific percentage to pass a song.

Modding

Charting

Controls

The game is played best on a MIDI piano or mini-keyboard controller.

The original PSX/PS2 era controllers can be unusually difficult to use, so be mindful if they stick or are a bit stiff, they likely need a good service and clean.

Trivia

bmson is based on a rewrite of the BMS format, but with an attempt to make it easier to make/parse for creators.
