If you have already installed Wine or Windows system, you can skip this step.
If you are using a Linux system, you may need to install Wine first. Use the following command to install it.
Ubutun/Debian:
sudo apt install wineOr compile from download binary files from the official website
The process of installing Note Block Studio is basically the same as other Windows software, so I won’t go into details here.
After the installation is completed, it will look like the picture below:

Click the Generate from MIDI file button, select your MIDI file, and import it:
Click the Save Song button:

In this way, your nbs file production is complete.
