What is Soflan? - Rhythm Game Terminology 

DDR has a way to combat soflan, that being the lane covers. theyre used for slow sections so you dont get overwhelmed by the amount of notes on the screen

One thing to note about Ace for Aces is that the soflan is actually different for every difficulty of the song, so you have to memorize the speed changes of whichever difficulty you play, not just the song

Camellia and Nanahira put out a track called "Confusion Girl Soflan Chan" and the song has 183 BPM changes and 252 time signature changes. You can see them being counted in real time in the small window above the note lane in this clone hero chart for it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CtK0C0ycY-w.html It is absolute insanity.

*forgets the song literally named soflan chan

Really great video! I didn't know that the keysounded notes in Shockwave Syndrome correspond to stops. A few extra notes - In SDVX Exceed Gear (the latest version), a number was added next to the BPM/LANE-SPEED numbers that appears when a soflan is about to occur, showing what BPM and LANE-SPEED the chart will go to. Introduced in SDVX III, there is a song by Camellia ft Nanahira called Konran Shoujo♥Soflan-chan!! (混乱少女♥そふらんちゃん!!), which is all about soflan. It ranges from BPM 32-259 and centers around the gimmick, with over 100 BPM and time signature changes, though only 33 are reflected in the chart. It also makes an appearance in pop'n music, which handles soflan similarly to DDR. Back in the day when soflan was more sparse, DDR and Pop'n players used to put towels over the top part of their screens to reduce the visible lane size, then take it off during a speedup. This makes reading much easier because in the slower sections, you become less overwhelmed by the lower scroll speed, while still being able to use it for the faster parts.

7:55 Sudden+ though??!? Being able to slap lane cover on/off during pauses is so helpful; it singlehandedly carries my ability to read OT"P" lmao

very surprised you covered Y&Co in that way. I've seen a couple of players (most notably CORIVE) play the chart on non-random/MIRROR - this allows them to hold down the start button on Lightning cabs during the speed-up, hitting the blue key with their thumb, and alternating between hitting the white keys and floating in real time to offset each other to make the transition back to normal speed way easier. definitely one of the more wild techs in recent memory lol

Soflan is actually a great description of both my musical style and charting style in Guitar Hero, since when I make charts, I'll often change the beat lines to match up with stutters, unison impacts, and other effects. Since scroll speed isn't affected by BPM in Guitar Hero, this doesn't have the effect it would in other games (which is a good thing, since these BPMs can often get into the thousands, and can change very rapidly). I haven't written a full-on soflan song in a while, but it is definitely something I enjoy doing, especially for comedic effect.

'the jump to 318BPM is actually a bug' ... yeah add that one to the list, haha. I guess I do remember hearing 3rd Style CS had its fair share of bugs? CHAOS is definitely one of my first thoughts when talking about this sorta thing. don't have any SDVX experience but that was neat to see.

Soflan in SDVX is basically charting to include the start button

I've never had much experience with soflan since I mostly played Gitadora which practically has no soflan because the scroll speed is always constant and BPM only determines the density of notes.

Too bad you didn't talk about popn. In popn you can use sudden, but you have to hit a number on a keypad, which is significantly harder than in IIDX. As someone who plays both popn and IIDX, popn songs are much more likely to have soflan in them, and they are more likely to have soflan be a significant portion of the difficulty of the song since 95% of the time you don't use sudden.

New video from Losermanwins 🎉 Been waiting since I found your channel talking about iidx about a year ago Hope to see more content soon

surprised you didn’t mention n/a on iidx, the chart has a ludicrous soflan section that plays exactly like mei

I feel dumb not knowing Sudden+ also did that, I thought the lane cover only helped with making the lane more readable.

your videos are such comfort food really interesting and entertaining in a really mild way which is just so good

Geeeez, what a wacky charting style ;u; Actually pulling off the speed adjustments mid-song and playing the sections must feel pretty rewarding, meep! Noice overview of Soflan stuffs!

very unfortunate that you didn't mention Re:son D'etre from SDVX, it has nearly *FIFTY* BPM changes.

ITG MFs when the chart says no CMOD: 😨

me when the iidx section starts: "please don't make me think about hanakanmuri please don't make me think about hanakanmuri please don't make me think about hanakanmuri"

Fun video, a lot of effort keep it up

15:05 man, that was epic.

awfully late to the party but ongeki features negative scroll speed on occasions! afaik you never have to read a map in reverse but there's some funny holds in some songs where the play field starts scrolling in reverse halfway through (happens at the end of take)

I'm just thankful they don't do Soflan in Gitadora.. :))

very informative, thank you!!!

Am i wrong or, is Soflan interchangeable with SV (Scroll velocity), i know a few charts in games like Quaver where the BPM in the song is consistent, but for sake of emphasis, or to complement the beat of the song, the scroll velocity is changed, sometimes resulting in slow downs, speed ups or stops (sometimes even rewinds, in the case of Time Traveler by KNOWER) are these... not the same thing? Sorry if it's a really stupid question, i'm just new to the term soflan specifically, and, looking at the charts in the video, it reminds me a lot of SV charts

i feel sometimes DDR players have to built different to play shi like that i can play with my fingers but not my feet

I absolutely despise this style of charting. It's the biggest reason I turned off bpm changes in stepmania

*ppl who play arcaea having nightmares with arcahv

Never been in-time to your new upload before It's pretty peculiar that even Konami has accepted the terminology as of iidx 27

*laughs in -3/4*

Damn, I was literally in the process of making a video about sof-lan... Good stuff though

Where's ENDYMION ?

Sound Voltex looks f*cking awful to play and sounds atrocious. Stepmania had a good solution for solflan in the form of constant speeds like C200 or C400 which totally negated having to worry about stops or drastic speed changes. I wish they would have done that in the arcade games.
