beatmania IIDX Glossary

This page covers the most common terms found in beatmania IIDX and its fan community.

4KEYS: Replaced in 3rd style by LIGHT7, this was intended as a beginner-friendly mode that used only the four white keys. Available only on beatmania IIDX, substream, and 2nd style.
5KEYS (10KEYS on Double): Available for home versions as a specific mode, this plays exactly as 7KEYS, except that the last two keys farthest from the turntable aren't used. This is probably a compatibility issue with original beatmania controllers, so that owners of the original could still somewhat play beatmania IIDX, only having the 5-key controller at hand. In arcade versions of beatmania IIDX, 5KEYS has been available from the start as a special gameplay option, most likely as an attempt to help players of the original series make the transition. Starting with 7th style (and 10th style CS), 5KEYS was turned into an ASSIST modifier, allowing it to be used with notecharts other than the ordinary 7KEYS mode. From 10th style arcade through DistorteD, songs using this modifier counted as EASY CLEARs; the CS releases didn't save 5KEY scores until ASSIST CLEAR was introduced in GOLD. 5KEY was removed in beatmania IIDX 26 Rootage.
ANOTHER: The most difficult play mode -- harder than HYPER and much harder than NORMAL. Prior to HAPPY SKY, ANOTHER charts did not have their own difficulty ratings and would display as the same difficulty as the HYPER version. Some tracks have an ANOTHER that sounds different from the original song. ANOTHER is intended generally for experienced players and usually contains notecharts with a difficulty of 9 to 12. Not every song has an ANOTHER version, though songs without ANOTHER charts typically originate from older styles.
ASSIST: A category of modifiers that automatically play notes for the player, including 5KEYS, AUTO-SCRATCH, LEGACY, and any combination thereof. Charts cleared with ASSIST modifiers will be marked with an ASSIST CLEAR until the player achieves an EASY CLEAR or higher. Notes that are automatically played do not count towards EX score, so while ASSIST mods can help in clearing the chart, they will reduce the maximum EX score attainable due to the lower number of playable notes. CS releases prior to GOLD CS do not save scores with the ASSIST mods 5KEY and/or AUTO-SCRATCH.
ASSISTED EASY: Introduced in copula, this Gauge modifier behaves in the same way as the EASY gauge; the passing requirement is also lowered to 60%.
AUTO-SCRATCH: An ASSIST modifier that automatically plays scratch notes. Prior to GOLD CS, scores with this mod did not save in the home releases; from 10th style arcade through DistorteD, though, scores cleared with this mod were counted as EASY CLEAR.
BACKSPIN SCRATCH: A scratch note in which you must continuously spin the turntable and then spin it in the opposite direction at the end of the note. The initial scratch and the counter-scratch are judged separately. Introduced in SIRIUS.
BEGINNER: This mode was added in 9th style (5th style CS for home version). BEGINNER gives an alternate note chart for nearly all songs from levels 1-3. From 9th style to PENDUAL, BEGINNER was a separate mode with only BEGINNER charts, thus severely limiting the number of songs available in a game. As of Lincle, several BEGINNER charts from console versions (and earlier arcade styles) were revived. Prior to HEROIC VERSE, scores do not save for BEGINNER charts, and all songs have a generic green clear lamp.
BLACK ANOTHER / KURO ANOTHER: An even harder play mode than ANOTHER difficulty, available on DJ TROOPERS CS and EMPRESS + PREMIUM BEST only. While not every Black ANOTHER chart is rated level 12, several of them are, and have astoundingly high note counts. MENDES' Single Black ANOTHER chart is notorious for having the most notes of any Single Play beatmania IIDX chart ever, with 2626 notes.
CHARGE NOTE: A note that must be held down and then released when the note ends. The initial press and the release are judged separately. Introduced in SIRIUS.
CLASS / DAN ININTEI (DAN): This mode serves as a skill-ranking system for beatmania IIDX players. Modeled after the Dan system for many martial arts schools, players are ranked from 7th Kyu (the initiate level; 5th Kyu on Double prior to copula) all the way through 10th Dan (the highest rank attainable). Each rank consists of a course of four songs (three on Double prior to copula), each rank being harder than the last. The highest rank a player can achieve can be considered that player's relative "skill level," and is a decent way to gauge player ability. In DistorteD, an extra rank above 10th Dan was added, called Kaiden, that is designed to truly test a beatmania IIDX master's skills. A new rank was added in copula called Chuuden, as a bridge between 10th Dan and Kaiden.
CLEAR RATE: The ratio of clears to total attempts by all players on the e-amusement network on a given chart. It is expressed as a percentage that is shown for the currently-selected chart. Introduced in IIDX RED.
DOUBLE PLAY: A play mode in which the player uses both sets of seven keys and both turntables.
EASY: A GAUGE modifier that consists of a modified GROOVE GAUGE that sustains lower penalties for misses. In the arcade versions only, from 10th style through DistorteD, songs with 5KEY and AUTO-SCRATCH on also counted as EASY CLEAR.
EX HARD: A GAUGE modifier, similar to the HARD gauge but with harsher penalties missing a note (BAD/excess POOR: 10%, POOR: 18%). It has a yellow GROOVE GAUGE.
EXPERT: This mode is one in which you can play a course of songs in a row without stopping. You start with the gauge at its maximum; if it drops to 0, the game is over. The gauge is the same as that used in Hard mode in normal play, but drops at a much slower rate. EXPERT mode was removed beginning in tricoro, but has since returned in PENDUAL, this time as a software update.
FREE: Similar to Standard/Arcade mode, with the exception that there is no limit on the which songs can be picked for any particular stage. On home versions, play in Free Mode will continue endlessly until the player chooses to return to the main menu. On arcade versions, Free Mode allows for the player to play two stages, but the player can pick any song for either stage without limits on difficulty and without having to worry about Game Over if a song is failed.
FREE PLUS: A variant of arcade versions' FREE mode, but exclusively for two players and with three stages.
FULL COMBO: Clearing a song with the maximum possible combo; in other words, clearing a song with zero BADs and POORs (other than POORs sustained by excessively pressing keys). Beginning in 10th style, achieving a FULL COMBO results in a splash graphic accompanied by the text "FULL COMBO".
HARD: A GAUGE modifier that consists of a modified EXPERT gauge that sustains higher penalties for misses, 6% for BADs or excess POORs, 10% for POORs. If the gauge drops to 30%, the penalties are decreased. If it drops to 0, you immediately fail the song.
HAZARD: A variant of FREE mode, but with four stages and a new restriction: if you break combo at any point, you fail the song instantly. In arcade versions, it is accessed by highlighting FREE on the mode select screen and pressing the three black keys simultaneously. In console versions, it is a GAUGE modifier accessed by holding down the key to change gauge modifier as you select HARD gauge.
HELL BACKSPIN SCRATCH: Introduced in copula, they are exactly like normal BACKSPIN SCRATCHES, but they replenish the GROOVE GAUGE gradually the longer they are spun, and they can be started at any point in the scratch. If stopped too early, they decrease the GROOVE GAUGE gradually. In the English version of HEROIC VERSE, these are called "Special Backspin Scratches".
HELL CHARGE NOTE: Also introduced in copula, they are exactly like normal CHARGE NOTES, but they replenish the GROOVE GAUGE gradually the longer they are held, and they can be hit at any point in the note. If released too early, they decrease the GROOVE GAUGE gradually. In the English version of HEROIC VERSE, these are called "Special Charge Notes".
HI-SPEED: A modifier that affects the scroll rate of the chart. However, the chart itself and the song remain unchanged, with notes spread out to compensate. Early versions of beatmania IIDX have only one setting, but newer versions add more options; tricoro and onwards in particular allows adjusting the HI-SPEED multiplier with up to two decimal points of precision.
HYPER (old styles: 7KEYS for Single, 14KEYS for Double): This is the standard play mode -- harder than NORMAL, and easier than ANOTHER. It is intended for intermediate players and usually contains notecharts with a difficulty between 6 and 10.
LEGACY: An ASSIST modifier that converts Charge Notes and Backspin Scratches to regular notes. If used within a chart with no Charge Notes or Backspin Scratches and said chart is cleared, it will be marked with a standard clear lamp.
NORMAL (old styles: LIGHT7 for Single, LIGHT14 for Double): This mode is a degree of difficulty lower than HYPER. It is intended for beginning players and usually contains notecharts with a difficulty between 1 and 7.
PERFECT COMBO: Clearing a song with all JUST GREAT's and/or GREAT's.
PREMIUM FREE: An arcade-exclusive variant of FREE mode that allows you to play as many songs as you wish for a specified amount of time, similar to console versions' FREE mode but with a time limit; by default, 6-, 8-, and 10-minute modes are available. You can quit a song any time by pressing the EFFECT and VEFX buttons. This is a PASELI-only mode, and costs more than a credit of other play modes in exchange for this convenience.
REGUL-SPEED: Modifier that makes any song played 150 BPM, ignoring any BPM changes as well. Scores do not save while this is on.
SINGLE PLAY: A play mode in which the player uses one set of seven keys and its corresponding turntable.; This article is a stub. You can help complete this page by filling in missing information and/or by correcting any errors.
