    |----------------------------------------------- How to use -----------------------------------------------|

    How to use:

    • Bind your keys:
      Install the mod and open your game, go to settings -> controls -> vehicle and bind every key that you want to use
    • Enable chase mod:
      Chase Mode needs to be enabled in order to toggle sirens, rumblers and warning siren
      It's enabled as soon as the lightbar is on and default game's siren is off
      In order to enable chase mode you can either use the default lightbar key from the game or use the Chase Mode key from the mod
    • Use the UI apps
      Control app
      To use the control app, simply add it on the UI and press the buttons to use the functions
      Sounds selector app
      Simply add the app on the UI and select the sound you want for the vehicle you are in.
      Pressing the save button will remember the preset for the selected vehicle
    |------------------------------------------------ Questions -----------------------------------------------|

    Important: All presets are made inside the file for more versatility, but this comes at a cost any mod update will remove your presets, so make sure to save them somewhere!

    Video tutorial:
    (Pause the video if it's going too fast)

    Text tutorial:
    First step open the file and go to presets, duplicate the .Default.json file and rename it to the name of your preset. For example: My Custom Preset.json

    Then, open the file you just create and modify the path of the sounds.
    Sounds are located in

    So let's say you want to add duck.ogg sound, put the sound in and inside the preset json file you gonna put "sound": "mysound/duck.ogg".

    Note: wav sounds also work, I guess other sounds work but I don't have a list of compatible formats. volume management is not in pair with engines volumes, which means that if you put your in-game volume to 100, sirens are going to be very loud and engine not so much. But if you put your in-game volume to 5, sirens will be very quiet compared to engines.

    To fix this issue, simply set your in-game volume to 50 (or any volume that gives you a good balance between engines and sirens) and then change the game's volume using Windows Volume Mixer

    Note that this issue can't be fixed until the game's fmod engine can be modded

    You need to restart the game at least 1 time to get the mod working. (install mod / start / restart and it work)
    If you the mod was disabled and you enabled it, you have to restart the game overwise the mod won't work

    Try to clear the cache of the game.
    Sometimes problems are caused by incompatibility with other mods! So, try to uninstall all other mods except this one and then, if it turns out to be working, reinstall them 1 by 1 to find which one is causing issues.

    This is due to the type of sound that I use for the sirens
    This bug can't be fixed until the game's fmod engine can be modded

    However you can reduce the issue by increasing your sound quality in game's sounds settings

    I will fix this issue when as soon as I find a fix, for now I'm still trying to find one, sorry for the issue

    See How to use -> UI apps -> Sound Selector

    For some strange reason, I have a keybind set up for the manual siren tone (Numpad 6), but pressing it does nothing, could someone help me fix this?

      I think it's a bug from the game, if you're using AZERTY (and prolly others too) you cannot bind every key from the top numbers

    Not really user friendly for people who use their mouse for steering, could there be key bind controls other than clicking it?

    So I can't find the two UI apps in the mod hub (the soundboard selector you can click and the two things on the side of the screen. I don't know if they are already included or if they rant showing up but could you link them?

      Author's Response
      The apps are included, you need to go to the UI edit mode and they should be in the list

    Can't find a forum so I'll say it here, this mod used to work and I loved it, but some time ago it stopped working, the UI apps do not appear despite them being added to the screen, making it impossible to use, time for maintenance.

      Hey, first thanks for not putting 1 star.
      I tested the mod myself and I don't seem to have any issue, are you sure the issue is not from your side? You can try to clear cache / uninstall other mods etc

    Just realized looking at your github that there is a Nergy400 Series but I'm using GeForce now to play and it doesn't show up in the siren selector. Not sure if it's supposed to or not supposed to.

      Hey, I have the audio file for some sirens but I didn't include them into the default presets because they sound bad most of the time
