How to insert in this time signature?

While Im browsing wikipedia seeking in depth infos on music, I found that time signature is not limited to 7/4 only. There is more complex time signature more than I know.

From this article:

"There are various types of time signatures, depending on whether the music follows simple rhythms or involves unusual shifting tempos, including: simple (such as 3/4 or 4/4), compound (e.g., 9/8 or 12/8), complex (e.g., 5/4 or 7/8), mixed (e.g., 5/8 & 3/8 or 6/8 or 3/4), additive (e.g., 3+2+3/8, fractional (e.g., 2½/4), irrational meters (e.g., 3/10 or 5/24), or other meters."

As title say, what if I found any of this signature? Wont it be troublesome as Osu! only have 7/4 metronome setting?

Higher than 7/4 (e.g. 9/4) is very rare, and when it does occur it is easy enough to .osuhax.

Additive time signatures should be done by redline barcoding or .osuhaxing larger time signatures (e.g. timing 4+3+3/4 as if it were 10/4)

Stuff like 2.5/4 should probably be timed in osu! with double BPM as if it were 5/4, or occasionally by putting a red line every 2 and a half beats. Fractional time signatures would be a mess to implement properly and would look awkward on the timeline.

I have never seen an irrational time signature and have no idea how they'd work or how mappable a song using one would be.

Neither do I, just a curiousity. I bet I wont found any of this shit anyway >.>

There's no (current?) support for signatures like x/8, and thus usually end up with halving/doubling the bpm to compensate.

Example: http://osu.ppy.sh/s/25062 7/8 song where the BPM was halved and had a time signature of 7/4

Oh right; damn my memory...

Please note that compound time signatures shouldn't be implemented in that way on osu!. 12/8, for instance, has 4 beats to the bar and each beat has 1.5 length. We implement this in osu! using 4/4 and 1/3 snap.

High prime time signatures are rare and can be osuhaxed.

I see, that why some having 1/3. Might study some more on this matters I guess. Might look for some song that uses 1/3 snap for my reference here in Osu so at least I know how to compensate the time signature here in Osu!

I Mapped this as bpm 330 with 13 beats to the measure.
I mapped this as BPM 165, with a timing section for 3.5 beats, then another one for 5.5

prime time signatures that can't be divided can be edited in through notepad. Alternating time signatures need a new timing section every time it alternates. Generally alternating time signatures can be expressed in some other form. My 2nd example could have been done in 3/4, but the second part would all be offbeat.
