When I tried to get a bpm edit of https://osu.ppy.sh/beatmapsets/874178#osu/1827120 , the program failed to generate a new difficulty. I assume this is because of the metadata, as once I shorted the artist (桐崎千棘 (CV: 東山奈央), 小野寺小咲 (CV: 花澤香菜)) to (kirisaki), the program was able to run successfully.

When you generate a map through a preset when using a hotkey, options changed in the preset (Scale AR, OD) are not applied the first time, and you have to press the hotkey again.

So essentially everytime you rename a preset and move your mouse outside of the little window it closes.
I personally find this really annoying and would like it to stay open even when I move my mouse away as I can not see anything if my big cursor is on the Text-Box.

I haven't downloaded Osu Trainer before and when I open the file it just shows the stuff in the file, I tried looking for tutorials, but found nothing but an old reddit post of some person with a similar problem with windows 11 from 6 months ago with only one reply that didn't help.

im not a coding expert but isnt this supposed to be for GTA V or something? When I open it, files start downloading into the folder. I have no idea why rage multiplayer updater is opening instead of the actual osu-trainer.

Pretty easy to replicate:

1. Set the rate for any beatmap to 0.0.
2. You will then get a division by zero crash, abort the program.
3. On startup, the program loads the last rate used, and will therefore crash again in a perpetual loop.

Crashlog:

************** Exception Text **************
System.DivideByZeroException: Attempted to divide by zero.

only happens on this mapset that I found: https://osu.ppy.sh/beatmaps/2814413
It doesn't glitch when I decrease bpm, and it has no problem with other beatmaps I tried.

Is there anyway to fix this?

someone please help

This makes the bug remain unfixed.

I'll simply change AR and it will duplicate all files in the song folder.

I am using Windows 11.

Add option to flip beatmap horizontally, vertically and both.
Pretty self-explanatory, this is an essential feature for a practice tool (McOsu has this and it's very useful to combat mindblock).

Some beatmaps like:
https://osu.ppy.sh/beatmapsets/1519813#osu/3110704
https://osu.ppy.sh/beatmapsets/1010487#osu/2115290

doesnt work.

osu trainer is skipping maps

If I change the song folder to anything that doesn't end in "Songs", the beatmaps are not detected, even though they are correctly proccessed and displayed in the osu! client.

this also happens on any other than the Program Files\osu! , such as other directories on C:\ or any external drives

As with every mp3 re-encode, the offset changes by approx 8 to 10ms.

Would it be possible to automatically add that offset to the entire map, so one doesnt have to use offset everytime?

Like when I did 1.1x with pitch change, it did a lower bpm than the original bpm.

it says

Object reference not set to instance of an object

this happened after i replaced a song file in the songs folder with another song file of the same name

Raising BPM of this map throws this error

Has someone got it working on Linux Mint or Ubuntu? I used the following script to install the game. https://github.com/NelloKudo/osu-winello

I started running into this problem a couple days ago, any way I can get it so that the custom difficulties I generate can open back up in Stable? Since there is no way to access the diffs in the Lazer directory I have no way of importing them into Stable since there are no beatmap files to import

If it should, then idk what am i doing wrong, but since for some reasons i just cant install/open modern versions of the game, i just tryied there and the maps werent being recognized by the program, i tried 1.7 and 1.6 versions, but neither has worked, both wont recognize them, anytthing i can do? (apart frrom updating the game oor using a modern version since, as i said i cant use modern versions)

There has been serveral times I tried to search this repo but end up getting no results because GitHub doesn't show forks in the search results. Since the project has been modified somewhat heavily could you please consider unfork it?

Seems to be when OD is set > 10.0. When this happens, the beatmap becomes slowed down instead of sped up.

Map: https://osu.ppy.sh/beatmapsets/781683#osu/1641637
Reason: The mp3 file is just called .mp3
Workaround: copy the mp3 file and give it a title like song.mp3 and set the diff I want to rate edit to use that mp3 instead, make my rate edits, and re-update original map.

Hopefully osu-trainer can handle mp3 files just called .mp3 in future so that this workaround isn't necessary.

With 4keys maps it works normally, but when i try to use it on maps with any other number of keys (1,2,3,5,6,7,8,9,10) it compresses all the notes into a broken 4k version.

Osu!trainer wouldn't want to detect any beatmap I click on, I tried reinstalling and it had no effect

For example, if "A r M i N's Extra" of padoru is selected when i open osu!trainer and i swap to any other difficulty or mapset, like black rover, osu!trainer will stay on "A r M i N's Extra" of padoru until i close and reopen.

From time to time a bunch of my edited maps lose the mp3 file, which is gone from the song folder and cannot be found in the Recycle Bin.

I do not know what triggers this or if it's an issue on osu! or osu-trainer's end. It appears to be random, since I have edited maps from months ago with mp3 still intact and one edit I created yesterday already has no mp3.

The IP 13.107.4.52 used for osu!trainer is found to be malicious.

AR change is not allowed so the trainer makes low BPM songs to use with DT when not needed
