EZ2DJ is a series of music video games created by the South Korean company AmuseWorld. The basic manner of gameplay is similar as in the Konami's Beatmania series; however, as the franchise continues, it differs[how?] in style of music and gameplay. The first edition of EZ2DJ was introduced in 1999 and last version, EZ2DJ Azure Expression ~Integral Composition~ was released in June 2012. Afterwards, following the lawsuit against Konami, the rights for franchise were given to Square Pixels company, and development continued under the title of EZ2AC, with latest version being EZ2AC: Time Traveller, which was released in August 2017.
EZ2DJ cabinet features a total of 10 speakers. There are four mid-range speakers stacked vertically on either side of the screen, and two subwoofers located on the front of the machine. The cabinet also features a pair of headphone jacks, giving players the options to use their own headphones. Using headphones does not disable the external speakers.
EZ2DJ cabinet features four red effector buttons, located at the top of the controller part. However, unlike the Beatmania series, depending on the game mode, effector button are treated as a gameplay button, especially in the game mode "Radio Mix", where each player need to control 2 effector buttons. Essentially this is very similar to the 7 key mode of Beatmania IIDX, but due to the location of these effector button—located in a row right at center of the console panel, right underneath the screen and away from the keyboard—it makes it even more difficult than Beatmania IIDX in some occasion (especially since it also use the pedal). Also, another game mode named "Space Mix" uses all four buttons along with all keys and turn tables (excludes pedals), becoming the hardest gamemode in the game.
Lawsuit and ruling
On July 10, 2007 Konami won a patent infringement suit against AmuseWorld. Konami had originally filed a lawsuit against AmuseWorld in 2001 over the same issue which they settled out of court. It is believed that this settlement was due to the continued release of the title. Following the second trial, a Korean judge's ruling ordered AmuseWorld to pay Konami damages and stop production of the product completely. AmuseWorld paid 11.7 Billion won in satisfaction to Konami.
