About this Mod
Simple Client-side mod that adds a new GUI for Note Blocks. GUI provides a clear choice of Notes which will automatically tune the block to the selected note.
Key Features
- Fully functional Client-side (works in multiplayer)
- GUI for Note selection
- Displays Current Note & Instrument
- Display all Notes as selectable buttons

How to use
The GUI can be accessed by either sneak right-clicking with an empty hand or opened when placing the Note Block (disable by default, see commands below). Once in the menu simply clicking one of the Note buttons will automatically queue and begin to the tune the Note Block to the desired Note.

By default you can queue up to 3 Note Blocks to be tuned at once. Ones after will be added to the queue and will begin processing once available. The mod will automatically adjust the delay between changing notes (this is to primarily avoid desync when on servers). You change the basic delay between cycles with the command (see below) however it won't effect the delay when in range of the target Note.
If you wish to completely stop all tuning process, active and queued for whatever reason. You can use the Stop All keybind (default \) which will completely stop all processes and clear the queue. This keybind can be changed through the in-game keybinds menu
Commands
/notedelay [1-20] - Change the delay between cycles. This is how many client-ticks to wait between each change./notequeue [1-5] - Change the concurrent tuning amount. This sets how many Note Blocks can be tuned at once./noteplace [true/false] - Change the menu to appear after placing the Note Block./notecolour [true/false] - Change the menu to display the Note colours on the Buttons.
