BlockTuner
by xwjcool123
With BlockTuner installed, players can tune note blocks in the world by sight and sound, and play a piano keyboard from the keyboard or a MIDI device.
What it does
BlockTuner is a utility for Fabric that gives a note block tuning assistant. Holding Ctrl shows the note of a note block under the crosshair, and right-clicking note blocks with blaze rods plays them without opening the tuning interface. Older builds did not need the Ctrl key, and the mod toggles that behavior through its own settings.
The mod includes a Play mode with an on-screen piano keyboard. A toggle controls whether the interface closes as soon as a key is clicked, and another decides whether the computer keyboard types notes. A MIDI Device option cycles through available MIDI input devices, and an icon shows red when the chosen device is unavailable, which usually means another program is using it. BlockTuner requires Fabric API, and the mod is server-side only, so it is installed in the server's mods folder and players still need it when they join a server that runs it. The files cover 1.16.4 – 1.20.4, and the latest Fabric build is 1.1.2 for 1.20.4, published on 2023-12-10.
Key features
Note block tuning assistant
Ctrl displays the note of the note block the player is looking at, so tuning can be checked before a block is changed.
Play mode
An on-screen piano keyboard lets the player play notes directly, with options for closing the interface after each click and typing with the computer keyboard.
MIDI input
The Click control cycles through MIDI input devices, and the top-right icon reports whether the selected device is available.
Blaze rod playing
Right-clicking a note block with a blaze rod plays its note, a quick way to test tunings in a world.

How it compares
BlockTuner is server-side only and open source under the GNU Lesser General Public License v3.0 only, with Fabric files for 1.16.4 – 1.20.4. MidiCraft is client-side only, not open source, released under the MIT License for 1.19 – 1.19.2, so it covers a different range and needs installing on each player's client. MCMidi is client-side only and open source under the MIT License, with Fabric files for 1.21.1 – 1.21.7, outside the range BlockTuner targets.
