Instruments Helper
by Nimq
Instruments Helper is a Fabric client mod that replaces the piano controls of CupOfCode's Instruments plugin with a larger two-octave keyboard, a song browser and a sheet-style trainer.
What it does
Once the mod is in place, a player opening the instrument screen on a server running CupOfCode's Instruments plugin gets a piano interface instead of the plugin's inventory controls. The keyboard resizes to the space the window offers, covers two octaves, and responds to mouse clicks and keyboard keys. Chord modifiers switch between major and minor, while sustain and octave-shift controls change how the notes ring and where the keyboard sits.
Song playback is handled by a categorized, paged browser with ten compact built-in songs. Players can also add their own songs, and a custom song with the same name as a built-in one overrides it. Runway mode shows notes on a staff-style display, which helps players follow a piece before playing it. The mod runs on the client only and needs Fabric API installed next to it. Files are published for 1.21.11 and 26.2, with 1.0.0+26.2 as the latest Fabric build, and the code is not open source.
Key features
Responsive piano interface
The keyboard scales to the available screen space, so the controls stay usable at different window sizes.
Chord and octave controls
Major and minor chord modifiers, plus sustain and octave-shift buttons, let players reach the full range of the instrument.
Song browser and trainer
Songs are sorted into categories and shown in pages, and runway modes display the notes in a staff-style layout to guide play.
Custom songs
Players can edit or add songs, and a custom entry overrides a built-in song of the same name.
