Generated the same I-V-vi-IV progression twice with real midiutil calls: the baseline script (skill ignored) never set a GM program change so the bass track would just sound like a second piano, while the skill run used the bundled generate_midi.py + voice-leading.md guidance to set correct bass/piano programs and cut total cross-chord voice motion from 21 to 9 semitones -- a concrete, measurable improvement, not a subjective one.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 8/10
  • Docs & honesty 5/5

What MIDI Generation does

Generates MIDI files with correct General MIDI instrument program changes and applies bundled music-theory references (chord progressions, voice leading, counterpoint, orchestration) instead of writing MIDI code from scratch. Triggers on requests to compose, generate, or create music/melodies/MIDI files; requires `pip install midiutil` and, for WAV export, a separately downloaded SoundFont plus FluidSynth.

How to install MIDI Generation

git clone https://github.com/tubone24/midi-agent-skill
cd midi-agent-skill
mkdir -p ~/.claude/skills
cp -r . ~/.claude/skills/midi-generation

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger MIDI Generation

  • /midi-generation Generates real .mid files via bundled GM-instrument scripts and music-theory reference docs, not ad hoc code.

It also activates on plain-language prompts like these:

  • Generate an 8-bar piano and bass piece using a I-V-vi-IV progression
  • Create a MIDI file with proper General MIDI instrument programs
  • Compose a short melody and export it as a real .mid file

Frequently asked questions

Is the MIDI Generation skill free?
Yes. The skill itself is free from tubone24/midi-agent-skill. SkillProof publishes the install command and an independent test verdict at no cost.
Does MIDI Generation work with Claude Code?

How do I install MIDI Generation?
Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
Can I use MIDI Generation with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
