Hello
Recently, there’s been an increase in people creating new packs and converting from Osumania to Etterna, so I wrote this article to explain the minimum standards.
I’m not an administrator, so this is just my opinion, but I hope it will make pack checking a little easier for administrators and be helpful for those trying to create new packs.

- How to Convert from Osumania to Etterna
1: Basic Rules
I’ll list four points.
-
Adjust the offset using waveform editing software (details explained in section 2).
-
Do not use sexually explicit images (CDtitles, background, banner, etc).

A huge reason why it’s not a good idea to put straight up explicit images in your pack is because there are minors that play Etterna, and Etterna is a game that isn’t JUST for adults.
By putting porn in your pack, you are technically giving children direct access to that content. -
No osu snap.

converted from osu to etterna, sometimes things will mess up and notes will be moved to a different snap, in which you need to just push them over to the right snap.
For now, please place it properly in the “red note”!!! -
No osuintro (not mandatory).

On osu, there is the ability to skip long empty intros. This feature does not exist on Etterna, so when converting your own files, please chart the empty space, or cut the audio and fix the sync so that the chart starts immediately.
2: How to Adjust the Offset
Either is fine.
・Download Old Arrow Vortex (Etterna HP Direct Link) ⇒ Click to download
・Download New Arrow Vortex (GitHub Link) ⇒ Click to download
Start (if dll required) ⇒ Click to see forum
※The steps to adjust the offset using Arrow Vortex are as follows
・“File”、“Open”、“sm file select” click in order

・“View”、”Time based(C-mod)”、“Wavefrom” click in order

・“Wave color & Filter color (Both can be any color)”
“filter type” (Filter color: Low-pass becomes larger, High-pass becomes smaller)
“strength” (The further to the right you move it, the smaller the filter color becomes.)
“overlay filtered wavefrom” (check)
Once you’ve set it up, click “Apply filter”

Any filter color & setting is fine as long as it’s easy to see.
・“Tempo”、“Adjust sync” click in order

・Touch “Music offset” to match the filter color to the guideline.
Before that, please use “CTRL + mouse wheel up/down” to zoom in and out on the waveform.

OK

asynchronous
Once synchronized, click “File” and then “Save” to save the file.
Bonus (Basic Note Operations) ![]()
These operations are useful when fix snap.
“CTRL+A” selects the entire score.
“CTRL+X” cuts (“CTRL+C” copies).
“CTRL+V” pastes the cut note at the start point shown in the image.

Pressing “CTRL+A” makes the note glow white.
The paste point is from the judgment arrow.
3: How to Convert from Osumania to Etterna
Unzip the osz file and check the contents of the map folder.
Delete the 1.1, 1.2, 1.3 etc speed osu files (because Etterna allows you to play any file at any speed).
Download OMtoSMConverter ⇒ Download link
Launch it and drag and drop the folder into omtosmconverter.

Converted for Etterna.

The offset will not be correct, so adjust it with Arrow Voltex
Second Bonus (osu conversion sample pack)
![]()
For this pack, I converted my favorite songs that I listen to every day on Osu Mania.
The offsets are roughly synchronized…maybe
Of course, please do not rank this hobby pack. If you find a map you like and want to include it in a pack you are working on, it is important to get permission from the map creator.
