How I get VirtualDJ?

Click Here [www.virtualdj.com]

For that, I'm just showing you how to change or lock the BPM of the song so that it doesn't have BPM variation.

First, you need to import the audio you got from YouTube or some other site using the ClipGrab, using the before method. Example.

Open your VirtualDJ.

It will look like this.



i recommend to you change the decks and layout for “PRO”

As in the image below



I like the other theme, feel free to switch if you want.

I will switch to the “Old” theme
for that, you need to go into “settings”





Import that audio that you catch from ClipGrab.

As in the image below, “Example”



After loading, it will look like this.



Here's where you change the bpm (fixed BPM).



Switch for above or below
above = less BPM
bellow = more BPM

IMPORTANT

You need to check if the BPM of the music you are placing has in FMOD Studio, I will put all the BPMS available in FMOD Studio here. But if you know how music BPMS work and how to measure them, you can make Custom BPMS.

List from "FMOD Studio”



After deciding which BPM you're going to use, let's record this audio to edit in FMOD Studio and put it inside the game.

Click “Setttings”





Click “Record”.

In Filename. Give this file a name and a location where you will save it.

In format, you must use WAV.

Click “START RECORD” inside the submenu “RECORD”.



Click this buttom for playing the music.



Will recording the music, when almost finished, you need stopped.



Like the an example below


I removed the audio from the video due to Copyright.

You can make custom BPM on VIrtualDJ.

its can might fixed or variables BPMS, it's cool, right?

Okay. Let's do it.

On your VirtualDJ, you will see this.



In track the music, you will see then you have the text “BPM”, if you click in BPM Track, will show another window then you can make custom BPMS, it's can be fixed or variables BPMS.



in this window, you can edit the BPM variable, you can choose the bpm that can be up to 289, going beyond that may not change the bpm. Maybe it's a limitation of the program, I don't know.

after, you will see like in the image below. Example…



Now you can change the bpm for more or less, like in before section.

Example below.


After, you need to record the audio, I'll show you how to do this in section 1.5

You need to import the FMOD project from the file where we extracted the files.

Open your FMOD Studio

The Folder "MetalFMODProject" Contains the music and beat of the track..
The Folder "MetalFMODProject_SFX" Contains the game's "SFX" effects, so for now I don't know if it's possible to change that, I believe so..

You will see this window.



Click “Open Project” and select the folder we created in section 1.3 “Pile for Modding”.



You will see this window.



After that will, we used NoTiersSimpleSongNoActs, because it's more simple to do, however exists more templates that you can use.

Click “NoTiersSimpleSongNoActs”



you will see this



Delete the “Tier 1” – It's meaning music track



Drag your edited music to “Tier 1”



Delete “Audio 1”. Track – and set the same BPM as the music you edited, in this case it's 110BPM





You need to move the beat line to the same position as the music and the green and blue pointer must be decreased if necessary, as in the video below, the important thing is that the pointers stay together with the beat and the music.

Don't forget to change the BPM in FMOD Studio, where it's 120 and change it to your music's BPM.

Please note that different BPM in the same song, or any tempo changes, is currently not
supported and will cause erratic behavior.

Well, in FMOD Studio you have an audio button. If you leave it default, you can hear beatTrack sound strong, you can disable it or lower it. It's your choice.

This buttons



If your lowered this button, you hear less the beatTrack.
If you're raising this button, you hear more the beatTrack.

Quick Note: This also goes for music.

It's recommend to find the balance between this.

After that, you need to Build your music again and import to the game.

“Tier 1” – MUSIC TRACK.
“Audio 1”. BPM TRACK.

Well, according to the official documentation exists four templates, However. I'm use “NoTiersSimpleSongNoActs” and doesn't count in documentation.

You can find the official documentation here.

Metal Hellsinger: Official documentation [cdn.metalhellsinger.com]

Each template you use contains differences between them.











This model means that the music will play and repeat when it ends. This template has no stages, that means it starts playing when the game starts, including the vocals of the song.

Click the “Banks” tab and then click “Build”



It will generate a file in the place where we extracted the folder with the files.

C:Metal Hellsinger ModdingExportedBanksDesktop

Move both archives NoTiersSimpleSongNoActsBank and customsongs.json from your StreamingAssets in Metal Hellsinger folder.

Note: customsongs.json It's in an earlier folder if you missed it.

IMPORTANT

If you can't find the installation location of your game, I recommend you try to go through steam

C:Program Files (x86)SteamsteamappscommonMetal HellsingerMetal_DataStreamingAssets
OR
On steam, click on Metal Hellsinger >> Properties… >> Installed Files >> Browse…

Another very important step is to copy the GUID of the event so that the game doesn't crash.

Return to FMOD Studio go to NoTiersSimpleSongNoActs and click “COPY GUID”



Open “customsongs.json” where is located in:

C:Program Files (x86)SteamsteamappscommonMetal HellsingerMetal_DataStreamingAssets

To open .json files, you can open them with notepad, notepad++ or an IDE, in this case I'm using the Visual Studio Code.



Choose a phase, replace the Bank with the name of the file you renamed, replace the bpm with the music bpm and the GUID generated by FMOD.

Each level contains two possible replaceable songs, the Main music and the Boss music (end of every level).

Your GUID must be replaced in the “Event” tab for the song.
Your LowHealth can be changed for what you want, be creative.

BeatInputOffset is your main headache. If you start the track and do not stably hit the rhythm, but are sure that BPM is the right one – select the dial here. Experiment until you find the perfect offset.

Note - if the track wheezes in the game, make the music quieter in the game settings, put, for example, 60%, and return the desired volume level through the mixer on Windows.

Correct BeatInputOffset


Wrong BeatInputOffset

If you have problems with the sound, I recommend that you calibrate your sounds with the in-game calibration system, this can solve your problem especially if it is Bluetooth devices that usually tend to have some delay.

For that, go in Settings



and then click on

Short answer, yes.

At the moment I don't know how to do this, because I try to do it with other templates on FMOD Studio and my game crash…

In the official documentation say that you need to create new BANKS, however I made and don't work.

You can do that with the same BANK, in that case is the “NoTiersSimpleSongNoActsBank”, but using it that way may be allowing more memory usage as it says in the documentation.

You need usage the same GUID of the event before, if you do with the same BANK.

Use this at your own risk.

I'll update this section when I find the solution, so for now this solution works, but you need to be aware of what can happen if you do.
