What is SOUND VOLTEX

SOUND VOLTEX Series

SOUND VOLTEX is part of the BEMANI series of music games. The game series combines traditional button gameplay with the use of analog dials and sound effects, creating a unique sound and game experience.
PHQUASE is the current sound director of the series, while dj TAKA is the current sound producer, with DJ YOSHITAKA as the head producer.
Sota Fujimori is the composer of the BGM for the first four installments, from BOOTH to HEAVENLY HAVEN. PHQUASE composed the VIVID WAVE BGM, and SYUNN composed the EXCEED GEAR BGM.

What makes SOUND VOLTEX different from the other game series is that regular BEMANI artists (either KONAMI in-house or commissioned ones) are not prominent in the song list. Instead, artists renowned in the doujin and beatmania simulation scene are more common here, plus licensed EXIT TUNES songs and Touhou Project arrangements. There are also remixes of original KONAMI songs.
While at first the song list mostly consisted of original songs or licenses involving VOCALOIDs, late in the first game's release the artist selection greatly expanded thanks to what it is supposed to be the most important pillar of the series - the FLOOR section.

SOUND VOLTEX FLOOR refers to the group of competitions posted in its website where Japan-based artists can participate in, with a chance of their songs or remixes appearing in the games. Music contests have their own themes and rules, such as remixing a selection of an artist's songs, or using synthesized vocals. There are also contests related to designing jackets for brand-new songs or to replace pre-existing ones in the game.
Thanks to the FLOOR contests (and also to the presence of Touhou Project arrangements), the game quickly gained a lot of success, prompting the production team to focus as much as possible on these in the future. Contest winners may also be invited to provide original songs in SOUND VOLTEX itself or in other BEMANI games (most notably, five of the seven beatnation RHYZE members debuted in BEMANI via SOUND VOLTEX FLOOR).

From April 16th to May 15th, 2015, the first SOUND VOLTEX FLOOR contests (for original songs and appeal cards) exclusive to the rest of Asia were held. However, due to delays in communication between KONAMI, Korean distributor UNIANA and participating artists, the winning contest songs and appeal cards weren't added to the game until over two years later, on February 1st, 2018. (On December 21st, 2016, UNIANA stated on Twitter that it has sent out confirmation emails to all winning artists.)

As first seen in SOUND VOLTEX II -infinite infection-, new games of the series are released as huge online updates.

Unlike other BEMANI games, regular soundtracks are not released for the SOUND VOLTEX series. Instead, soundtracks tend to focus on ones from FLOOR contests. Listed below are the soundtracks that have been released so far:

Other original SOUND VOLTEX songs may occassionally appear in soundtracks for multi-game BEMANI events.

SOUND VOLTEX is also the first BEMANI game series to have licensed BMS (Be-Music Source) songs. In SOUND VOLTEX IV HEAVENLY HAVEN, it also added songs from major doujin labels such as HARDCORE TANO*C, S2TB Recording, and C.H.S.

Gameplay

For simplicity, the games will be referred to by their subtitles (BOOTH, infinite infection, GRAVITY WARS, HEAVENLY HAVEN, VIVID WAVE, EXCEED GEAR).

SOUND VOLTEX's gameplay is similar to other rhythm games like beatmania IIDX and GuitarFreaks & DrumMania. When a note reaches the judgment line in time with the beat, you press the corresponding button or turn the corresponding dial.

The game interface has 4 CHIP BT note lanes, and 2 LONG FX note lanes that each occupy 2 BT note lanes. BT notes are white and FX notes are yellow/orange.

In addition to the standard SHORT and LONG buttons, SOUND VOLTEX also has 2 analog dials, one on each side. By default, when a blue trail (left side) and/or a pink trail (right side) appears, you have to turn the respective dial(s) to "follow" the trail(s). These are known as ANALOG CHAINS.
The effects in the songs are game-related and are caused by LONG FX notes (distortion effects), ANALOG CHAINS (woosh effects), and special CHIP FX notes (added FX effects).

infinite infection introduced the following gameplay mechanics:

• SHORT note lanes can now have hold notes, known as LONG BT notes. Conversely, LONG note lanes can now have short notes, known as CHIP FX notes.
• The HARD-gauge style EXCESSIVE RATE is added. When the rate drops to 0% at any point, it is a TRACK CRASH.
• The INFINITE BLASTER unlock system/folder is added (since HEAVENLY HAVEN known as BLASTER GATE). It unlocks most game-specific special charts (e.g. INFINITE). This folder used to be available once the BLASTER ENERGY gauge is at 100%. Using the EXCESSIVE RATE gauge charges the BLASTER ENERGY gauge by 6.67% a stage (15 plays will fill it).
• A course-based mode, SKILL ANALYZER, was added. It functions similarly to beatmania IIDX's Dan / CLASS mode. A gauge exclusive to the mode, PERMISSIVE RATE, was added.

GRAVITY WARS added even more mechanics:

• Any combination of the BT and FX notes is now possible.
• ANALOG CHAINS may start from anywhere and go in any direction, and also extend beyond the chart lane.
• New charts may include zooming, moving, and even disappearing of the chart lanes.
• Colors of the ANALOG CHAINS can now be changed. Two new colors are also available: yellow and green.
• Hi-SPEED values can be tuned to an exact BPM value. They can also be stored by pressing 6 on the keypad for easy Hi-SPEED changing.
• EARLY/LATE indicators for NEARs can be shown in-game. They have 4 possible positions: LOWER, STANDARD (default), UPPER, and UPPER+.
• Timing can be adjusted to be earlier or later by holding START and then pressing 3 or 9 on the keypad, respectively. Values range from -8 to +8. Increase this value if you are getting many EARLYs and decrease it if you are getting LATEs.
• The ALTERNATIVE RATE SYSTEM (ARS) has been added to selected modes. This gauge starts with an EXCESSIVE RATE gauge, but when depleted (a TRACK CRASH normally), it will be switched to a EFFECTIVE RATE, at a level as if it were active.

HEAVENLY HAVEN introduced the following mechanics:

• A new default difficulty, MAXIMUM, is added. This difficulty is only present on new songs from HEAVENLY HAVEN onwards.
• MIRROR and RANDOM note options are added. MIRROR flips all input horizontally, while RANDOM makes all BT notes appear randomly (and sometimes mirrors FX notes). They cannot be used in SKILL ANALYZER.
• Special CHIP FX notes (colored yellow) produce added sound effects when hit. These vary from claps to bass drops.
• A new EXTRA STAGE system, named EXTRACK, is introduced. By filling the BLASTER GAUGE to 100% or playing on BLASTER START, the EXTRACK will appear after the FINAL TRACK. The BLASTER GATE folder is now only accessible on EXTRACK or the BLASTER START modes. Ω Dimension, a new EXTRACK-only folder, contains EXTRACK-exclusive charts available to unlock.

VIVID WAVE introduced the following mechanics:

• Speed and judgement offset can now be changed at the song selection menu.
• Sorting function has been slightly reworked.
• You can now change the colors of the key beams. Available colors are purple, pink, green, and yellow.
• The NEMSYS crew characters that appear in the results screen are now animated using Live2D (except for photographed characters).
• Timing values are changed from -8/+8 to -16/+16.
• As of December 17th, 2019, the BLASTER ENERGY gauge will be filled with EFFECTIVE RATE as well as EXCESSIVE RATE, with 6.67% per song played.
• HEXA DIVER, a new EXTRACK-only folder, contains EXTRACK-exclusive charts available to unlock.
• As of January 17, 2020, a purchasable item, BLASTER PASS is added, simplifying the gameplay for BLASTER-related unlocks.

EXCEED GEAR also introduced more mechanics and changes:

• A new cabinet, named Valkyrie model, is introduced, which allows access to some exclusive songs and other gameplay mechanics, such as the S-CRITICAL judgement. EX-SCORE is also displayed when S-CRITICAL judgement is enabled.
• EXTRACK gauge is added in which the player will have access to EXTRACK if it is filled. They are also separate with BLASTER ENERGY, meaning that the player can access BLASTER-related unlocks outside EXTRACK.
• The unlocking mechanics for BLASTER GATE and Ω Dimension were simplified, as players now need to clear or play 20 times (regardless of playing local or online) to unlock the charts. Playing a chart under BLASTER PASS instantly unlocks the chart regardless of results.
• The Hi-SPEED value is now displayed in hundredths and its value do not pertain to the BPM. Any BPM changes are also displayed beforehand during a song.
• The inclusion of "EFFECT RADAR", a radar representation for a song which evaluates the chart by its six parameters (namely NOTES, PEAK, TSUMAMI, ONE-HAND, HAND-TRIP, and TRICKY).
• ARENA START, allowing players to compete each other real-time (Valkyrie model exclusive).

To clear a song, your EFFECTIVE RATE must be 70% or higher (for all other gauges, never let the rate drop to zero). This does not affect charts rated Level 7 or below, however, as you will automatically be saved.

Modes

Initially, BOOTH only had two modes: ONLINE (single player) and FRIEND (local matching with 1-3 other players).

infinite infection added SKILL ANALYZER mode, that offers various 3-stage courses, most of which determines a player's Skill Level, and the rest being special commemerative courses. It also split all its modes to credit and PASELI/premium sub-modes when KONAMI further integrated PASELI into all its e-amusement games.

GRAVITY WARS, upon the launch of its SOUND VOLTEX GENERATOR -REAL MODEL-, added new GENERATOR-exclusive modes.

HEAVENLY HAVEN merged the SKILL ANALYZER mode into its main modes; now it can be selected while on your first stage. Normal and GENERATOR modes are now split into their individual sections. GENERATOR BLASTER, a GENERATOR-exclusive BLASTER START mode, was added. It also removed the FRIEND modes, as local matching can now be accessed by waiting out a timer after selecting a mode, like jubeat's local matching system. In addition, with the EXTRACK system added on August 10th, 2017, the number of playable stages has increased, and less emphasis is placed on BLASTER GATE.

VIVID WAVE now has six different modes. These modes are:

• NORMAL - the standard game mode.
• FRIEND - local matching mode.
• PARADISE - continuous mix mode.
• BLASTER - allows unlocking of BLASTER GATE charts and both Ω Dimension and HEXA DIVER tracks without BLASTER ENERGY.
• SKILL ANALYZER - now made as a separate mode for the first time since GRAVITY WARS.
• PREMIUM TIME - a time-based session mode similar to beatmania IIDX's PREMIUM FREE. Play as many tracks as you want within a 10-minute window. It is possible to set different challenges, automatically ending or retrying a track if the conditions are broken. You can also end a stage at any time by pressing the FX and START buttons simultaneously or hold them down to instantly restart the track.

EXCEED Gear adds two more game modes that are battle-based modes:

• ARENA BATTLE - a matching mode where two to four players compete in a set of songs, similar to beatmania IIDX's ARENA and pop'n music's Net Taisen mode.
• MEGAMIX BATTLE - a two-player matching mode compete in a pool of 10 chosen songs converted into a real-time megamix.

The game currently has the following entry modes:

Difficulty

SOUND VOLTEX has four main difficulties: NOVICE, ADVANCED, EXHAUST, and MAXIMUM (the latter introduced in HEAVENLY HAVEN).

Since infinite infection, the new games also have their own "special" difficulty, each named after their subtitles:

• infinite infection added the INFINITE difficulty, with a light purple hue (previously green with rainbow text).
• GRAVITY WARS added GRAVITY, with an orange hue.
• HEAVENLY HAVEN added HEAVENLY, with a light blue hue.
• VIVID WAVE added VIVID, with a pink hue.
• EXCEED GEAR added EXCEED, with a cyan/dark blue hue.

These difficulties are equivalent to each other, and these charts are usually added to songs from previous versions, adding the respective games' new gimmicks to otherwise old and outdated songs.

Difficulty ranges from 1 (the easiest) to 20 (the hardest) since SOUND VOLTEX IV HEAVENLY HAVEN. Previously, it was 1 to 15 in BOOTH, and 1 to 16 in infinite infection and GRAVITY WARS. When playing on LIGHT START, players are restricted to the following levels (first two stages only) based on the highest Skill Level attained in the SKILL ANALYZER:

Skill Level	GRAVITY WARS and earlier (16-level scale)		HEAVENLY HAVEN and later (20-level scale)
	First stage maximum	Second stage maximum	First stage maximum	Second stage maximum
Without e-amusement Pass	7	8	10	16
No Skill Level			16	18
Level 1 (岳翔)
Level 2 (流星)	8	10
Level 3 (月衝)	10	12
Level 4 (瞬光)	12	13
Level 5 (天極)	13	14
Level 6 (烈風)	14
Level 7 (雷電)
Level 8 (麗華)		15
Level 9 (魔騎士)	15
Level 10 (剛力羅)			17	19
Level 11 (或帝滅斗)		No limit	18	No limit
Level ∞ (暴龍天)	No limit		No limit

In the case of playing ARENA BATTLE, the level restrictions apply based on which class the player has obtained, tied to the VOLFORCE (each class has four tiers, separating minimum VOLFORCE requirements by 0.250 (S to C classes) or 0.500 (D class only)):

Arena class	Minimum VOLFORCE	Level Restriction
ULTIMATE (U1~U4)	20.000	No limit
S1~S4	19.000	19
A1~A4	18.000	18
B1~B4	17.000	17
C1~C5	16.000	16
D1~D2	15.000	15
D3~D4	14.000	14

Note that newly added songs (except for most original songs) have the NOVICE and ADVANCED charts always available by default. The other difficulty charts usually must be bought with BLOCKs / PCB. If not, they can be unlocked via BLASTER GATE, or through MISSIONs (in the case of GRAVITY WARS).

Scoring

All notes are judged as CRITICAL (perfect), NEAR (good; only for CHIP BT and CHIP FX notes), or ERROR (miss; breaks combo/chain). The maximum score of a TRACK is 10,000,000 (10 million).
Each note, when hit with CRITICAL timing, is worth (10,000,000 / total chain) points. Each NEAR note is worth half of a CRITICAL note.
EXCEED GEAR introduced another judgement, S-CRITICAL, which is a judgement stricter than CRITICAL. Its judgment is also worth the same amount of points as CRITICAL in the normal scoring system. This judgement can be enabled or disabled, and is exclusive to Valkyrie model.

Chain

Every BT note is counted as 1 combo chain. Every analog right-angle turn or "slam" also counts as 1 combo chain.
For LONG notes and analog chains, the combo chain starts counting after one beat from the start of the note/chain and ends one beat before. Each LONG note and analog chain counts as 4 combo chain per beat (2 per beat if the song's BPM is more than or equal to 256 at any time).

Grade

From BOOTH to GRAVITY WARS, your performance can be rated from D (lowest) to AAA (highest). The grade depended on both score and EFFECTIVE RATE level (or its equivalent level). The calculation of the "grade score" was:

(TRACK score × 0.9) + (EFFECTIVE RATE level[%] × 1,000,000)

The final grade then can be determined from this table:

Grade	"Grade Score" Range
AAA	> 9,800,000
AA	9,400,000 - 9,799,999
A	8,900,000 - 9,399,999
B	8,000,000 - 8,899,999
C	7,000,000 - 7,999,999
D	< 7,000,000

From HEAVENLY HAVEN onwards and in GRAVITY WARS コナステ, the grade range is expanded, adding the A+, AA+, AAA+, and S ranks. The rank requirements are also revamped, now basing it on score alone. See the following table:

Grade	Score Range
S	> 9,900,000
AAA+	9,800,000 - 9,899,999
AAA	9,700,000 - 9,799,999
AA+	9,500,000 - 9,699,999
AA	9,300,000 - 9,499,999
A+	9,000,000 - 9,299,999
A	8,700,000 - 8,999,999
B	8,000,000 - 8,699,999
C	7,000,000 - 7,999,999
D	< 7,000,000

RATE

Depending on which mode and the RATE used, each RATE have different increase for notes and damage penalties for each missed note. The rates for each respective gauges are as follows (the T rate is 280 meaning that clearing the song with all NEARs would only fill the RATE up to 69.9% [1]):

RATE type	Color	Clear Type	(S-)CRITICAL		NEAR	ERROR		Remarks
			CHIP notes	Analog chains Long CHIP notes		CHIP notes	Analog chains Long CHIP notes
EFFECTIVE RATE (EF)	Blue/Pink	Starts at 0.00% 70.00% clear threshold	+4T/n	+T/n	+T/n	-2.00%	-0.50%	Default gauge.
EXCESSIVE RATE (E)	Pink/Blue	Starts at 100.00% TRACK CRASH if depleted				-9.00%	-2.25%	Can be stacked with ALTERNATIVE RATE SYSTEM (ARS).
PERMISSIVE RATE (S)	Orange					-3.40%	-0.85%	Exclusive to SKILL ANALYZER mode.
BLASTER RATE (B) (Level 3 or less)	Rainbow					-4.00% X rank	-1.00% X rank	Used for unlocking BLASTER GATE and Blaster-related songs.
BLASTER RATE (B) (Level 3.5 or 4)					-1.00% X rank
HEXATIVE RATE (HD) (Level 4 or less)	Gold				+T/n	-2.00% X rank	-0.50% X rank	Used for unlocking HEXA DIVER songs.
HEXATIVE RATE (HD) (Level 5)					-1.00%

EX Score

Introduced in EXCEED GEAR, this alternate scoring is only available whenever S-CRITICAL option is enabled. The scoring for each judgement varies for both CHIP, LONG and analog chain notes:

Judgement	Normal Scoring (per CHAIN)	EX-Score
		CHIP notes	Analog chains Long CHIP notes
S-CRITICAL	100%	5	2
CRITICAL		4	N/A
NEAR	50%	2
ERROR	0%	0	0

Clear medals

When playing on an e-amusement account, or on the コナステ version, the game will record your scores and clear status on each song. This will be shown on the song select screen as a medal next to the song's jacket. Which medal will you receive depends on the best result you obtained playing that particular song; and by fulfiling specific play conditions, many songs and charts can be purchased (also called INPUT) in the SDVX Station.

The table below lists the possible medals obtained for a song (in order of lowest precedence):

Clear Medal	Medal color	Info
NO PLAY	No medal	The song has not yet been played.
PLAYED	Dull green	The song was played, but failed (or TRACK CRASH).
COMPLETE	Flashing green	The song was passed without using EXCESSIVE RATE. It is marked as a C (COMP in EXCEED GEAR).
COMPLETE	Flashing purple	The song was passed while using EXCESSIVE RATE. It is marked as a C (COMP in EXCEED GEAR).
ULTIMATE CHAIN	Flashing magenta	The song was passed by obtaining a ULTIMATE CHAIN (no ERRORs, a full combo-equivalent). It is marked as a U (UC in EXCEED GEAR).
PERFECT ULTIMATE CHAIN	Flashing gold	The song was passed by obtaining a PERFECT ULTIMATE CHAIN (no NEARs or ERRORs, a perfect full combo-equivalent). It is marked as a P (PUC in EXCEED GEAR).

SDVX Station

SDVX Station is the section of the game where you can buy in-game items using Blocks or Packets. You gain Blocks and Packets (or PCB since VIVID WAVE) by playing the game. Blocks (Blc) and PCB are used to purchase song charts, while Packets (Pc) are used to purchase Appeal Cards.

Since NOVICE charts are always unlocked, you will only buy ADVANCED, EXHAUST, and BLASTER (such as INFINITE and GRAVITY) ones. In SOUND VOLTEX BOOTH, you could buy single charts; in the sequel, you can choose to buy only the ADVANCED chart for a song, or all of them (except BLASTER charts) at once. Another difference between the two games is the absence of RANK requirements since SOUND VOLTEX II -infinite infection-.

Besides purchase costs, often there will be conditions that need to be fulfilled. These can range from clearing a certain number of songs to getting ULTIMATE CHAINS.

Since HEAVENLY HAVEN, you can buy charts direct from the track select screen. As such, the SDVX Station will only have the Appeal Card generator and POLICY BREAK sections. Due to the implementation of MAXIMUM difficulty for newer songs, many ADVANCED charts that previously required purchase from the Station are now unlocked by default. As the difficulty system was expanded, songs that previously required clears from a certain difficulty level has either been adjusted or removed altogether from the Station.

As of EXCEED GEAR, many returning songs can now be purchased using PCB without fulfilling prerequisites, including songs that required unlocking from BLASTER GATE and getting number of clears.

A list of purchasable charts can be found here:

• SOUND VOLTEX BOOTH Station Item List
• SOUND VOLTEX II -infinite infection- Station Item List
• SOUND VOLTEX III GRAVITY WARS Station Item List

Note that when playing new game versions, older charts must still be bought if you haven't done so before.

RANK System

IMPORTANT NOTE: The following section is obsolete due to the RANK system being removed in SOUND VOLTEX II -infinite infection-.

SOUND VOLTEX BOOTH Ranks

The purpose of the RANK System in SOUND VOLTEX BOOTH is to limit what song charts players can buy from the SDVX Station. There are 20 ranks in total, and you can raise them by accumulating Rank Points (RP). To accumulate RP you need to play songs and clear songs (getting ULTIMATE CHAINS or PERFECT ULTIMATE CHAINS makes the process faster). Once you gain a new Rank, you need to accumulate a new amount of RP for the next one.

The RANKS are:

1. Nameless Grass (0 RP)
2. Young Bud (30 RP)
3. Tree Leaf (70 RP)

  • It is also the second game overall (after TAITO's MUSIC GUNGUN series) to officially license Touhou Project arrangements from Team Shanghai Alice, developer and publisher of the Touhou Project series of games.
• Game size re-arrangements of the system BGMs of the SOUND VOLTEX games have always appeared as playable songs:
