In fact 1/8 patterns rarely appear in a song, and they should be restricted unless it's obvious to be 1/8... and the 1/8 shouldn't be long too. (5 maybe)

Authentics are not determined by SV=1.4....

It seems mappers participated in here usually prefer 1.4 but lots of them think it can't be forced, so basically there won't be some kind of restriction, though we may be able to recommend or advice to use 1.4. (Maybe mappers who supports 1.4 want some consistency with patterns so it can be easily read)

Anyway we need more opnions...

1.Countdown: Depending on the beginning of the song
2.Slider Velocity:126↓BPM=2.6-2.8,126↑BPM=1.4-1.6(1.4 is better)
3.Finish Notes in 1/4 streams: It will affect map artistic,so it doesn't permit
4.Kiai Time: Decides according to the song
5.Note Combo: (4)
6.Drum rolls: Namco also in using
7.Spinners: Restrict them by some way(4)
8.Overlapped notes by BPM Changes:(4)
9.Break Sections: not
10.1/8 notes:(4)
11.Sudden change of Scroll speed:(4)
---
i can only reply these
"don't forget that your map does for who"

Ok let's arrange these opnions...

Countdown: At first lots of mapper said there should be no countdown in Taiko map, but as discussion progressing, there are many opnions that we don't need to regulate that. So just saying 'We recommend not to use countdown, but if you think it's better, feel free to use it.'. Is it sounds fair?

Slider Velocity: Still lots of mapper favors 1.4, but can't force it to every map, so let's say 'recommend 1.4 but feel free to use other value, unless it's too high or too low.' Is it sounds fair?

1/8 notes: 'Avoid using 1/8 notes, and 1/8 stream over 5 notes is considered as annoying.' Is it sounds fair?
Some more opinions:

aabc271: Should be avoided unless in very slow songs like BPM <80
arien666: Avoid unless it's a crazy map.
aquabluu: Should be restricted to songs with BPM of <170

Big Notes in 1/4 streams: Seems most mappers don't like this so let's just say 'don't use Big Notes in 1/4 streams in SV=1.4.' Anyway we need to set exact limitation, as mappers sometimes set SV other than 1.4.
Opinions for Exact limitation:

lepidopodus: Over SV=1.8, Big notes in 1/4 stream is allowed.
Zekira: Allow if the BPM is lower than 85.
aabc271: Restrict less than 1/4. Over 1/3 is ok.
wmfchris: Allow if the BPM is really low like BPM 100.

Kiai Time: 'Do not overuse.', and maybe we can add 'putting it in chorus parts is recommended'... and maybe some more.

Note Combo: Seems there's no need to regulate this. Just say 'Do not overmap too much.'

Drum rolls: 'Do not spam.'
Some more opnions:

Rokodo: Avoid 2 in a row.
aabc271: Avoid shorter than 1/1.
aquabluu: No more than 5 in a row.
Lokamp: Don't stack 4-5 sliders on a row, avoid series of sliders which changes speed continously.
MMzz: Ends and starts should be at least a half a measure apart.
wmfchris: Drumroll should at least last 1 beat, dense rolls should be avoided.

Spinners: 'Do not spam.'
Some more opnions:

lepidopodus: End of sppiner should be at least 1/2 away from the next note.
Zekira: No overlapping.
aabc271: End of sppiner should be at least 1/2 ( 1/1 is recommended ) away from the next note.
Lokamp: Don't insert too many on a row.
crystalsuicune: Avoid notes immediately after spinners.
Natsumerin: Make it as closer to the next note as possible.

Limitations for note speed change (SV change): We got some suggestions. 'You can use SV changes over this limit, only when you have good reasons for it.' <--- How is it?
Opinion for Exact limitation:

lepidopodus: x0.5~x4.0 (Technically it will be doubled BPM with x2.0.)
Zekira: x0.33~x3.0
0989596108: ~4.0
aabc271: x0.33~x2.5

Overlapped notes by BPM Changes: NO

Break Sections: 'We recommend not to use it, unless the song is long.', looks fair?

Measures and Barlines: Need to add uninherited section if it's needed. Pulse needs to be corrected.

Some opinions may omitted by mistakes orz
Still this is opening for other opinions.
And I think we can add some advice to mappers, like samiljul said, 'It's not good to put sudden, very long streams of 1/4 notes in the map filled with 1/2 streams.'...?

Ok, asking some questions I have not seen.

Spinner lenght.-
I've seen the "do not spam" and " don't place a note/slider too close to it. What about the lenght of it?

SB.-
Some storyboards seem ugly on taiko diffs. Should this be regulated? A different storyboard should be used for a taiko diff? or should we avoid storyboards on taiko diffs?

Video.-
Same as above

Background.-
(Yeah, i'm pointing out visual stuff) Making a different backgroundwith roko's template is not hard enough. Should a different background for a taiko diff be forced? or it may use too much space in the end?

That is

Countdown: up to the mapper, but better no.
Slider Velocity: 1.4~1.6. if the song is really slow, maybe could increase it a bit.
1/8 notes: for <100 BPM: it's fine to use it, 100~160: better not to use it, but if not more than 5 combos it's acceptable. >160: if there's not a good reason i'll just say no.
Finish Notes in streams: for <100 BPM it's fine. but not more.
Kiai Time: depends on the song.
Note Combo: i don't mind it..
Drum rolls: consider the current situation osu's drum roll can't be the same as authenic... so another use could be "for 1/4s"
Spinners: if OD is not high it's easy for every user to finish, make it as closer to the next note as possible.
Break Sections: "few notes sections", but not break.
Overlapped notes by BPM Changes: it's ok if not weird.

Well these are my personal opinion.


Others are not that different from other mapper's opinion but this kinda conflicts with some mappers, anyway we need to discuss about this, maybe.
My case I sometimes feels hard with clearing spinners even ith OD=5, but when I use differnt key with same keyboard with same arrangement, it's easier to clear that. Anyway I'm worrying about the next note can be interupt too much if the note is too close to the spinner.

(That 'Overlapped notes by BPM Changes' seems too ambiguous and it confused everyone orz)

Spinner - imo there should be some break (1/2) between a short spinner (1 beat?) and the next notes. But for longer spinner it doesn't matter.

Background - The "taiko background" provides a bar to let people know what they're playing. But in osu we can know that from the windoe frame so I don't think a different background is forced to be used.

=======More idea========

As taiko's HP bar isn't drained during empty time, I think there's no need to set up break sections.

Speed change: At least it should be changed between two streams, but not during the streams to confuse players?

1/4 Big notes: A footnote should be made that if the song is obviously fast, then BPM 2xx 1/2 big notes is ok~

Agreed with spinner thing, though I think every spinner should be 1/2 away from the next note.
About background, yeah, we don't need to force that, though we can introduce something about that.

Ah, that speed change, I agree about that, slight change of the speed change (let's say 'less than x0.5') isn't that problem, but I think sudden big change of speed chagne during 1/4, 1/6, 1/8 streams is too much.

This is no longer actieve for the rules since Shimedore's Oni is with 1414 notes even it's authentic
orz

We already made that rule obsoleted long time ago, arken.

lol 45 days late reply.

WHY NOT

Countdown: No
Slider Velocity: 1.4. If it's to slow, use an inherit throughout the song.
1/8 notes: Unless you know what you're doing here, don't.
Finish Notes in streams: Uhh, depends on stream speed? But no.
Kiai Time: Use it in choruses and such, no limit of usage...
Note Combo: If it surpasses 3 minutes and you wanna make some sort of crazy Oni, then it's fine. Don't let this limit you.
Drum rolls: Scarce use. DO NOT use it for every long note in the song. Maybe use it to label Inner Oni pathway :3
Spinners: If used in a cool way that makes sense it's fine. Can be used as a ninja note, and made very long
Sudden change of Scroll speed: Uhh, hard to explain how this would fit. It's fine if you wanna add a ninja note, I guess.
Overlapped notes by BPM Changes: Yeah, this is bad.
Break Sections: Noooo. Tire the person! Kill his arms! He deserves it!
Measures and Barlines: Uh, what? I guess it depends...

I never saw this thread o.o

Countdown: NO.
Slider Velocity: 1.40.
1/8 notes: If the song's <75 BPM, you can. the SONG, not the map. (ee. Sack, 35 BPM. inb4 who would map this ?)
Finish Notes in streams:^ (but not with 1/8 unless the SONG is <40 BPM)
Kiai Time: Don't spam.
Note Combo: 99,999 (who would do higher ?) **EDITED because my pootin' Taikomiza is going to 8.000 notes, that is friggin' huge**
Drum rolls: Use them.
Spinners: Not too long (Don't do Mosquito like I do : Making a 300-hit spinner)
Sudden change of Scroll speed: Ninjanoting yeah, else use progressive change (Rokodo does on some of his maps.)
Overlapped notes by BPM Changes: Seriously this is s・・・(I miss because of intempestive BPM changes that are x0.5 x1 x0.5 x2)
Break Sections: Break as using 2/1 notes ? yeah. Else no.
Measures and Barlines: I HAVE NO CLUE.

How does one make a short drumroll in TaikOsu? A short slider gets converted into 2 notes...
