# Sound Voltex

Sound Voltex (Japanese: サウンド ボルテックス, stylized as SOUND VOLTEX, often shortened as SDVX) is a series of music games developed and published by Konami. The first release of the game, Sound Voltex Booth, was tested in various cities in Japan from August 26, 2011 until September 19, 2011. It was then released on January 18, 2012. Since then, 5 sequels have been released, with the latest version, Exceed Gear, being the first to release in North American territories.
The gameplay follows the formula of several other arcade and mobile rhythm games such as Beatmania IIDX and Arcaea, requiring the player to press buttons corresponding to "notes" approaching the bottom of the screen from the end of a simulated corridor. The game is likened to Beatmania in that the control scheme is intended to simulate performing as a DJ; rather than using a disc, Sound Voltex includes two control knobs to interact with "laser" notes.

## Overview

* A Generator Real Model in a cabinet
* A SOUND VOLTEX IV cabinet
Sound Voltex has two different parts that relate to each other: Sound Voltex Booth and Sound Voltex Floor. Sound Voltex Booth is the main game, while Sound Voltex Floor is a system wherein game content is created by Japanese artists and musicians. Content chosen from Sound Voltex Floor will be inserted into Sound Voltex Booth and become available in the game. An optional Generator Real Model can be installed on a cabinet to allow it to print cards.

## Gameplay
### Controls

Various objects, otherwise known as notes, come towards the player on the course lane, which consists of 6 columns with rails. The player is required to input corresponding commands when the object reaches the Critical Line at the bottom of the screen. The command required will differ, depending on the objects. Four white buttons in the middle of the controller are used to hit the white notes. Two additional types of input are also required: two black buttons beneath the main four buttons, and two knobs on the top right and left corners. The black buttons (known as FX buttons) are used to hit the orange notes (FX notes). These not only add an extra layer of difficulty, but also add effects to the song, similar to that of a DJ mixed song. The knobs are used to control blue and pink lasers on the screen; the player simply turns the knobs in the direction of the corresponding laser. The left knob controls a blue laser, and the right knob controls a pink laser. The laser colors can be changed by the player (chosen between pink, blue, green and yellow) but a warning will always appear on the corresponding side of the screen a short time before a laser starts, with a white "L" or "R" on a background color corresponding to that of the laser, to indicate which knob the player should turn. A blue button on the top of the controller acts as the "Start" button, also being used as an "Okay" button of sorts. On the arcade cabinet, holding the start button whilst turning the right knob will change the lane speed. Lane speed is the speed of which the notes go down (this is as of Exceed Gear, older versions may require a different command).

### Rate systems

As the player hits the objects, a judgment is received–from highest to lowest: S-Critical (Valkyrie Model only), Critical, Near, and Error–depending on the timing of hitting the objects. Getting S-Critical and Critical fills the rate gauge, while Error depletes it. From SDVX II onward, Near also fills the gauge, but fills 1/4 of the amount compared to S-Critical or Critical. The player is required to fill the rate gauge a certain amount (most commonly 70%) by the time the stage ends to clear it; otherwise the play session will be over. The amount required to fill the gauge differs depending on the rate system the player is using.

### Skill Analyzer

Skill Analyzer mode is a mode added in SDVX II, which can let the player test their Skill Level. The player selects a course to play which will immediately begin after selection. Each course increases in difficulty depending on the Skill Level. Each Skill Level has 3 different courses for the player to select.
There are 12 Skill Levels as of SDVX III, each of which are named after colors, from the lowest Lv. 01, Bronze (岳翔) to the highest Lv. ∞, Purple (暴龍天).
