Metrognome

by Baivo

Metrognome lets players play MIDI files through the in-game instrument blocks, with the song library and track controls kept in one screen.

FabricClient-side onlyMIT LicenseOpen source1.21.11

What it does

Players pick a .mid file from the menu, adjust it until the sounds match what they want, save it to the library and play it later. Holding a instrument and right-clicking it opens the screen, and pressing M brings up the menu to browse and choose a MIDI file. Playback drives clicking keys, and closing the screen stops the song. The mod is client-side only, so players install it alone and servers need nothing; no install on a server is required.

Every instrument has 24 keys across two octaves, and most music is wider than that range. Where a note falls outside the instrument's range, it is shifted to the closest octave that fits, and the coverage line below the controls reports what share of the song is playable. Metrognome is built on Fabric API and is released under the MIT License as open source, with the source code, issue tracker and wiki publicly available.

Key features

  1. Song library

    A selected MIDI file is saved to the library, so a song can be picked and played again later.

  2. Track mute and solo

    Left-clicking a track mutes it and right-clicking solos it. Dropping the bass drum track often helps more than soloing a melody.

  3. Note range handling

    Out-of-range notes can be handled by a smart mode that keeps the melody connected, a simple mode that shifts whole octaves, or a mode that drops them.

  4. Whole-song shift

    The song can be shifted as a whole, and a re-convert option lets players hear the result of changes after pressing U.

Adjusting a MIDI file

Players who find a song too wide for the instrument can shift it, choose a range mode and check the coverage line until the notes fit.
