. It is the sequel to the ''
beatmania'' game series, and is part of the
Bemani line of music games.
Initially conceived and developed as a sequel to ''Beatmania'', Konami released ''Beatmania IIDX'' in Japan in 1999. The development team designed the game to simulate the experience of a DJ performing at a real venue, and gave the cabinet a "club
Visual Jockey style."
While its predecessor used five keys, ''IIDX'' had seven of them, increasing the games complexity and skill ceiling.
The larger controller was integrated into the cabinet alongside a larger 40-inch widescreen monitor, dual speakers, and spotlights to replicate the feeling of performing at a live venue.
Gameplay
''Beatmania IIDX'' tasks the player with performing songs through a controller consisting of seven buttons and a
turntable
A phonograph, later called a gramophone, and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound. The sound vibration waveforms are recorded as corresponding phys ...
.
Hitting the notes at the correct time increases the score and groove gauge bar, which if equal to or above 80% on Normal difficulty will allow the player to clear the stage. Failing to hit the notes at the correct time depletes the players groove gauge until it is empty.
Starting from ''
beatmania IIDX 17 SIRIUS'', two new note types are added: Charge Notes, which require the user to hold and release buttons in time with the music, and Backspin Scratches, which involve spinning the turntable in one direction and then turning it in the opposite direction at the end of the note. ''
beatmania IIDX 23 copula'' introduced a variation called Hell Charge Notes, which refill the gauge when held down but rapidly deplete it when not. Unlike regular Charge Notes, they can be pressed at any time, though missing the start or end will still break the player's combo.
Aside from standard single play with seven buttons and a turntable, ''Beatmania IIDX'' offers doubles play-style, where users can play with fourteen buttons and two turntables. Certain versions of ''Beatmania IIDX'' have modes that are available in both single and double play-styles such as Course mode, Step-up and Arena. In Course mode players are challenged to complete four songs in a row of similar difficulty with a shared health bar, if the health bar reaches zero during any song, the game ends. Step-up mode allows players to play up to four songs without fear of a game-over. However, only a small selections of songs will be available. Arena mode matches up to 4 players in a competitive lobby where each player can pick one song, whichever player performed the best across all 4 songs wins.
Difficulty levels
Originally, ''Beatmania IIDX'' difficulties ranged from "Level 1" to "Level 7". However, ''
beatmania IIDX 5th Style'', ''
beatmania IIDX 10th Style'' and ''
beatmania IIDX 11 IIDXRED'' added "Flashing 7s", "Level 8" and "Level 8+" respectively.
With the release of ''
beatmania IIDX 12 HAPPY SKY'', songs were re-rated on a new difficulty scale ranging from "Level 1" to "Level 12". This has remained the standard in all subsequent releases.
Groove gauge
When playing a song in ''Beatmania IIDX'' players can set how their groove gauge functions. Easy & Assist Gauge will drain slower on misses, with Assist lowering the bar to clear to 50% instead of the usual 80%. Hard & EX Hard Gauges drain at higher rates when a player misses, and do not regrow as quickly as other gauges. When a Hard or EX Hard gauge hits zero, the song immediately ends.
When a song is cleared, a player will be rewarded with a lamp relative to the gauge used to clear. Available lamps are: Fail, Assist Clear, Easy Clear, Normal Clear, Hard Clear, EX Hard Clear & Full Combo. The lamps appear next to songs during song select.
History
In 1997, Konami distributed its Games & Music Division's (G.M.D.) ''Beatmania'' in Japan as a DJ-themed arcade title, significantly influencing
rhythm games. Its surprise success influenced the developer to rename itself Bemani, a
portmanteau
In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau—is a word formed by combining the meanings, and parts of the sounds, of two or more words together. of "Beatmania", and the studio made several spinoffs following its release, including ''
Pop'n Music'' and ''

''.
Due to the success of ''Beatmania'', Konami developed and released its sequel 2 years later in 1999.
Bemani developed several updates to the game after its release, Including a crossover in ''
Beatmania IIDX Club Version'' (later ''
Substream'') cabinets with ''
Dance Dance Revolution 2ndMix'' machines for simultaneous play, leading to increased success & popularity. In late 1999, the publisher hired artist Goli to design graphics and characters for ''
Beatmania IIDX 2nd Style''.
The next game in the ''IIDX'' series, ''
3rd Style'', featured a new aesthetic and was ported to the
PlayStation 2

.
In 2002, ''
8th Style'' was released after the discontinuation of the original five-key ''Beatmania''. Foster said the updates popularized the game to the point that it overshadowed ''Beatmania'', and ''IIDX'' earned more new songs and became known for being very difficult.
A sequel with a five-key controller, ''
Beatmania III'', was released in 2000 but did not see similar success. ''Beatmania IIDX'' still receives yearly arcade updates which feature new songs, new theming and new events.
Home releases
A video game named ''
Beatmania'' was released in North America in 2006 for the PlayStation 2, This was one of the only official ways to play ''Beatmania IIDX'' in the west.
In 2015, a PC release titled ''beatmania IIDX INFINITAS'' was announced, and began alpha testing in September.
On January 29, 2020, ''Heroic Verse''s LIGHTNING MODEL cabinets received a North American release.
On August 5, 2020, a new version of ''Infinitas'' was released.
This new version is similar to the Lightning upgrade for arcade releases, having support for 120 Hz displays and an improved engine.

Japan Amusement Expo, representing three

Hardware

The ''beatmania IIDX'' cabinet has many standard features that are found in traditional arcade cabinets such as a widescreen display, powerful speakers, and start buttons. Also, unique to ''IIDX'' cabinets are the effector buttons and sliders, a bass platform

, marquee, and DJ simulating controller. The effector buttons and sliders allow the player to control the volume levels within the game and manipulate the music by adding additional sound effects. The bass platform vibrates beneath the player's feet to the beat of the music being played. The marquee is a series of
sixteen-segment display LEDs, used to display game information and scores during gameplay.
Controller information
''beatmania IIDX'' controls consist two sets of seven
keys on each player's side, along with a

on each side. The turntable for the left player's side is to the left of the keys, while the one on the right player's side is to the right.
Each set of keys is arranged in a pattern of four white keys beneath three black keys. The black keys are offset from the white keys so that each pair of adjacent white keys has a black key above and in between them. This arrangement mimics the F, F#, G, G#, A, A#, B keys on a

keys. The keys are commonly numbered 1 through 7, from left to right. The four white keys are numbered 1, 3, 5, and 7; the three black keys are numbered 2, 4, 6.
Along the release of ''Beatmania IIDX 25'' ''Cannon Ballers'', two cameras are installed, one on the metal cage pointing to the controls, and another at left pointing to the players. Initially, the game would not boot up if the cameras weren't attached; this was fixed after initial release. After the release of ''Beatmania IIDX 26'' ''Rootage'', QR code reading functionality was added to the left camera.
With the release of ''beatmania IIDX 27'' ''Heroic Verse'', a new cabinet called LIGHTNING MODEL was introduced. The effect sliders, LCD marquee and keypads have been replaced with a touchscreen called the Premium Area, located under the screen where the sliders used to be. Due to the removal of the slider panel, the start buttons have been relocated to the upper-left and upper-right of the 1P and 2P keys respectively, and the VEFX and EFFECT buttons are located above the coin slot, as with 5-key beatmania machines. The front of the cabinet also features 3.5mm headphone jacks on each side, although this does not mute the speakers.
e-amusement
Since ''9th Style'', the game has featured integration with Konami's ''e-amusement'' platform, which uses a card inserted at the beginning of the game to save stats, scores, allow customization, and track scores in comparison to previous plays and against others over the internet. A
magnetic card reader was used from 9th Style to Happy Sky (12th). From ''Distorted'' onwards the newer type
Contactless smartcard Konami ''e-amusement'' Pass system has been used. ''9th Style'' did not require an internet connection to use a subset of the ''e-amusement'' functionality, but 10th and on required an internet connection to function, which must be provided by a subscription from Konami. Some versions can customize frames, BGM in SELECT MUSIC screen, notes, etc.. ''e-amusement'' is not available outside of the primary markets for ''IIDX'' (Japan, Asia, and the United States), which has left imported machines outside of Asia without full access to hidden songs and extra stages due to the increasing functionality and integration of ''e-amusement'' in more recent styles. However, new songs from ''e-amusement'' enabled styles can still be accessed on console versions (which can be imported from Japan) or in INFINITAS. As of ''Tricoro'', required an internet connection to startup instead. As of ''Rootage'', offline kits are returned.
Internal hardware
Each game since 9th style runs on a ''
Bemani PC'', a custom PC based system designed specifically for
Bemani's games. Games prior to 9th style use Bemani Twinkle, which in turn is a

. There is also a 120 Hz main display and a touchscreen second display. Older versions of the cabinets running PC based hardware generally were significantly weaker as they did not have to power 2 displays. The final revision prior to the Lightning Model use ''Bemani PC'' ADE-6291, that is powered by an AMD RX-421BD, an R7 Radeon GPU and has 4GB of RAM.
Music
Music is an integral part of the ''beatmania IIDX'' series. Featuring a wide selection of
genres and
artists, both licensed and in-house, the ''Beatmania IIDX'' series is well known for its original music.
Konami produces an
original soundtrack of each game, usually a few months after release, due to the appeal of the music. Konami also releases original albums by ''Beatmania IIDX'' artists through its online store,
Konamistyle. It's also a tradition that Konami crossovers some songs from and into other Bemani games such as ''
Pop'n Music'', ''

'', and ''
Sound Voltex''.
Each new AC release typically features around 60-100 new songs (+100 since ''Rootage''), with a selection of songs returning from previous versions and some songs having LEGGENDARIA charts. The current release, ''beatmania IIDX 29 CastHour'', features a library of over 1500 songs. Some songs are split across difficulties or styles. CS releases feature all of the new songs of their corresponding AC versions (with limited exceptions), 5-10 CS exclusive songs, around 25 "revival" (returning) songs, and 1-3 preview songs, for a total of around 60-100 songs (''Empress'' uses 2 discs, each with 99 songs per disc). Arcade versions since ''9th Style'' run on Bemani PC, rather than the

-based Bemani Twinkle, allowing them to have more songs with higher quality sound due to larger hard drives and higher end hardware.
Songs often include music videos when played, although only some songs contain dedicated videos. Some songs contain generic videos shared by multiple songs, and some of these have additional animated graphics overlaid atop them. Beginning with ''beatmania IIDX 19 Lincle'', players can select ''Qpro'' characters or customize them, and some songs show Qpros as part of overlays (exc. in ''beatmania IIDX Infinitas'', due to Qpros being unsupported). Beginning with ''beatmania IIDX 20 tricoro'', overlays of some songs were removed, and in ''beatmania IIDX 9th Style'', the effector system is not available, both due to hardware limitations. Beginning with ''beatmania IIDX 25 CANNON BALLERS'', the effector system is expanded to 8 effect options, adjunt with EQ ONLY. In mobile games and in ''beatmania IIDX Infinitas'' (2015), the effector system is disabled.
