RPG MAKER MZ Plugin: Simple Radio System
Radio System
Hello! Thank you very much for your interest in our plugin:
Radio System.
Before we continue, we would like to remind you that all of our plugins work within the environment:
RPG Maker MZ ↔ PC Windows ↔ NWJS
If you use other platforms or devices, we cannot guarantee correct operation because unfortunately we have no way to test them. Please keep this in mind before proceeding.
Below you’ll find more details about what this plugin offers.

FULL-EXPERIENCE MODE
Plugin Details: Radio System
With this plugin, you can incorporate a fully functional, interactive radio system into your game. It provides a visual interface that allows players to listen and discover new stations while they explore your world.
Unlike modern music players, the plugin is designed to mimic the feeling of a real-world radio, complete with frequency tuning and the ability to unlock specific broadcasts as the story progresses.
Features
- Advanced Audio Handling: This plugin uses specialized audio technology to allow multiple sound channels at once; this means the radio can play independently of your game standard background music.
- Dynamic Station Management: You have complete control over which stations the player can hear. You can setup playlists to game events, meaning a "Secret Station" will only appear in the radio list once the player has reached a specific point in the story or triggered a certain event.
- Interactive Graphical Interface: The plugin adds a modern radio UI directly on your game screen. Players can easily toggle the radio on or off, adjust the volume, and switch between different frequencies using either the mouse or a gamepad.
Use Examples
- Secret Frequency Collectibles: You can hide "radio frequencies" during your game as collectibles or rewards. A player might find a scrap of paper in a desk with a hidden number like 90.3; once they tune their radio to that exact 90.3 frequency, they might hear a secret message, a hint for a puzzle, or a rare music track that wasn't available before.
- World-Building & Immersion: Use the radio to tell your story without stopping the gameplay. You can have a "News Station" that updates the broadcasts after every major boss fight or plot twist.

Differences between the Versions
Demo versions are early builds of the plugin. They have fewer features and differ significantly from the full releases. However, they serve as examples: they allow you to quickly grasp what the plugin can do and often provide enough functionality for smaller projects.
Demo versions do not receive direct updates. As they are early editions, their contents have been improved and updated in the full versions. The demos are free to download on itch.io using the “Download Demo” button.
Full versions are the complete releases of the plugin. They include all features and receive ongoing feature updates and constant support. (Remember that support is always provided for the most recent version of the plugin.)

What is a FULL EXPERIENCE MODE plugin?
At Undermax we always want you to have the best experience, and we know that DEMO versions don't always showcase all the plugin's capabilities. Maybe you're unsure whether to buy the FULL version of the plugin. That's why, in some of our plugins, you can download and run a demonstration example of that plugin in its FULL version so you can try it in a closed and safe environment.
This lets you explore in greater detail those features and improvements that the DEMO version doesn't offer.
Keep in mind that the FULL EXPERIENCE MODE only lets you run the plugin in this project and it will not be compatible with other personal projects. This means you wouldn't have access to the original plugin file, which you would receive if you purchased the FULL version.
FULL EXPERIENCE MODE plugins are only compatible with PC devices running Windows, which is the environment we work with.

Hi Undermax, I want to buy it, but have some questions about the functionality. Is there a way to determine which sound is being played, or which frequency is being played?
1) I want to I want to trigger the event or turn on Switch or ShowText when the player choice the correct frequency/sound.
2) Is there a way to make the sound only play when a switch is turned on, otherwise, even if the player selects the correct frequency, the sound will not play?
Hi! Thanks for reaching out. Let me inform you:
At the moment, the plugin does not include functionality to detect which song or frequency is currently being played, however, this is something that could be added in a future update of the plugin.
Regarding your second question, the system currently allows you to block entire Playlists, but not individual tracks.
This means you can make the radio only play the desired station if a specific Switch is ON. Otherwise, the station will not appear in the list and white noise will be played instead.
I hope this clarifies your questions. Have a great day! ^^
Best regards,
Undermax
Thanks for the quick reply! It's good to know that I can unlock each sound using the switch.
Regarding point 1, I wonder if the radio sound is the same as the sound play function of RPG Maker?
I mean, I can use script: AudioManager._currentBgm.name === "Battle1" to check if the Battle1 sound is playing in the game or not.
So, I wonder if this script works with this plugin to determine what sound this plugin is playing?
Hello, responding to your question. In this case, it's different. What we are using are mainly HTML5 Sound features since this allows us to have multiple audio channels, which is what we needed for the plugin to work correctly. RPG Maker MZ has channel limitations, so it is handled differently :)
Anyway, I invite you to try it out and see if it works for you and is useful. If you need anything, I will try to help you.
Thank you for the reply. I will try out this awesome plugin!

Is the music in the demo allowed to be used in comericially sold games?
Hello! How are you? Well, I really couldn't give you an answer to that Because the music used allows reuse as long as credits are given. I really don't know if the YouTube channel where I got it from has a resale clause. I would recommend you to have your own music and song selection to avoid problems. The music information where I got it from I think I put it in the credits file.
Thanks for the fast reply
Is there a way to add and remove tracks based on events/switches?
How are you doing? Thanks for your message.
Unfortunately, my friend, since the way the plugin works, that's not possible. What you can do is show playlists based on whether a switch is active or not, but individual songs can't be hidden since the system handles files independently.
Is it possible to customize the UI to fit the rest of the game UI?
Hello. How are you? The system uses CSS and HTML in general, Reason why it doesn't use the default Window Skin of rpg maker. You can customize various aspects such as colors, sizes, And other aspects from the plugin parameters. But if you want to use your game's windownskin then unfortunately it won't be possible. In any case, you're sure to find a style that suits your project well. :)
