This tutorial will show you how to easily create a song or simfile for DTXMania with Guitar Pro by converting MIDI to DTX file.

DTXMania is a free japanese Guitar Hero-like rhythm game but for drums trainings only.
The PC game is available for Windows and a non official android version is also available for japan only.
You can find 3 versions:
DTXMania v3 (simple version), DTXMania XG VerK and Gitadora (advanced version)

Let's get started !

Step 1: Export a MIDI File

You need to convert your drum sound or partition into MIDI format.
You can easily export a MIDI file using GuitarTux (a free alternative to Guitar Pro).
This step will save you a lot of time and effort.

Search and download your guitar pro instrumental on https://www.ultimate-guitar.com/ .
Open the file with GuitarTux, remove all the tracks (guitar, bass etc.) located at the bottom and leave only the drums.
Click File -> Export ->MIDI

Step 2: Convert the Midi File to DTX File Using the Program MIDI2DTX

You can download MIDI2DTX here

Step 3: Create the Folder for Your Song

Put the DTX FIle in it (.dtx format)
Download a random DTXmania simfile on internet and copy the sound effects (.XA) to your new song folder
Download the mp3 audio of your song and put it in your song folder. This will be your background music (BGM).

Step 4: Edit Your DTX File in DTXCreator

Open your DTX file in DTXCreator (usually found in the same folder as DTXMania)
Go to WAV tab and asign the mp3 audio in the 1st row as your background music (BGM).
On the drum chart, there's a BGM section. Click at what moment you want the audio to start playing.

Step 5: Sync the Audio With the Notes. This Is the Most Important Part.

Hit the play button to verify if the drum hits are synced correctly
If the notes are late, right click on any part of the chart and click "add/remove part" or "change part lenght" to increase or decrease the duration of that part.

Step 6: Once Your Music Is Perfectly Synced, Time to Add the Sound Effects

Sound effects are in .XA format.

On the WAV tab, locate the note numbers that appear on the drum chart.
Each columns correspond to a part of your drumset.
On the table in the left, assign each number to a its corresponding sound effect.
When you are done, save and close the program.

Now you can put your song folder/simfile in the game folder and open DTXPlayer to start playing.

Note: if you are not sure what sound effects to use. Check the guitar pro tab/partition in Guitar Tux.
