Music Command Generator for Minecraft

Browser Compatibility

It is recommended to use this app on a desktop/laptop instead of on mobile.

The app has been tested on recent versions of Google Chrome, Safari and Microsoft Edge. Internet Explorer is not fully compatible. Since this is a client-side app (It is run entirely by your browser, no data is sent back the server for processing !), some essential functions may not work if your browser hasn't been updated for a long while, or your device places many restrictions on it.

This site does not use any cookies.

PWA : This app can work offline, using the features of Progressive Web Apps  . Click the 'Try Offline' button in the footer to cache the resources to do so (this will only take around 3 MB of space). If your browser supports these features, it will show you an option to install this website as a native application on your system ! On mobile, you can equivalently save it to the Home Screen.
Note : On desktop, PWAs may not be fully supported in browsers other than recent versions of Chrome, Edge & Safari. Even without the installable app, you will be able to use the website without an internet connection. You can clear the cached website from your browser settings if you wish to do so.

Miscellaneous notes

• When you create the add-on, commands to build all the Midi-machine which plays the music in-game that was uploaded and processed will be written into it. Every floor of the machine plays 2 seconds of song leading to around 65*50 blocks being used in x-z axis (which is a lot !), Given your initial coordinates, make sure that one y level below is ready to be replaced. Every noteblock placement is accompanied with corresponding music block and per unit time has a full range of redstone wire as per the Minecraft audible range. they are regular commands like /setblock, More instructions on running the functions are given below.
  Read more about functions in Minecraft.


• The converted audio heard after you click the 'Process Audio' button may vary in quality depending on the song chosen (especially in the "noise"generated due to limitations in minecraft noteblock sounds being 8-bit sounds) This is unavoidable. You can change your experience by selecting/deselecting some instruments which will change the overall quality of the song.


• Make sure to keep enough room in y aixs for the midi machine to fit completely as even 20 sec song wil take 10 floors wit heach floor being 4 blocks high. Do not place two midi machine in an overlapping manner as that will lead to breakage in mechanism.


• The fill commands to clear the map volume of existing blocks (default, unless you checked the "Replace only air blocks" option) may fail in case your simulation distance is too low. In this case, existing terrain above and below the 3D map blocks will remain, possibly hiding the blocks that were placed there.

In Minecraft

1. Import and apply the behaviour pack to your world(s).
   Note : Cheats & Operator permissions must be enabled to use functions. If you want to earn achievements in that world or keep cheats off, you'll have to place the blocks manually (You can look at the Survival Guide for some help).
2. Go to the location where the midi machine is to be built, and stande near the staring point but dont stand inside the buildable region.
   
3. The syntax of the function command is /function machine_name.
   For example, if your machine name was onesummerday (make sure to keep names with no spaces and no capital names), you would need to run the commands

   /function onesummerday

   
   Note : You may need to restart Minecraft and then run the /reload command first, in case they don't appear in the commands screen or minecraft hasn't recognised the functions
    
4. You're Done !

   Once you've constructed the machine, there will also a railcart system built in order to enjoy the song lesiurely.
   All you need to do is sit in the cart and press the button.

Example behaviour pack

This is the file structure of an example behaviour pack generated by this app. It contains 2 images - one with the function name "cliff" of size 2x1, and another named "bastion" of size 3x2. You can run the commands as described above to build these images.

            behaviour pack.mcpack
             │
             ├─ manifest.json
             ├─ pack_icon.png
             ├─ structures/
             │    └─ mapart/
             │         └   ...
             └─ functions/

                  │    ├─ 1.mcfunction

                       ├     ...

• The manifest specifies :
  • The minimum game version - 1.20.0 (of Minecraft)
  • Behaviour pack version - 1.0.0 is used for each pack by default. (Only this sample pack has version 4.5.0)
  • The name and description that you entered, will be displayed for the add-on in game.
  • 2 version-4 UUIDs to uniquely identify the pack, generated randomly using the JS web Crypto API.
  You can always edit the icon or manifest if you prefer to make any changes later on.

The pack contains some structures (with block data) of a few blocks that may decay or need support (non-solid blocks) etc - these structures are used instead of the setblock command to overcome those limitations. Every pack will contain these even if they are not used in any image(s).

To view/edit/replace the files inside, just rename the .mcpack extension to .zip and extract all contents using any Compressed (ZIP) folder utility.
