Generate Custom MIDI Clips with Natural Language Prompts Using MIDI Agent
By midiagent •

Tired of staring at a blank piano roll, waiting for inspiration? Imagine simply describing the music you hear in your head and watching it appear as MIDI in your DAW.

MIDI Agent makes this a reality. This powerful VST3 plugin connects to cutting-edge AI models, allowing you to generate custom MIDI clips with natural language prompts directly within your favorite music production software.

What Does "Natural Language Prompts" Mean for Music?

Think of it like talking to a musical collaborator. Instead of manually clicking in notes or playing a keyboard, you type instructions in plain English.

For example, you could ask for:

  • "A simple, melancholic piano chord progression in C minor"
  • "An upbeat, funky bassline loop in E major for 4 bars"
  • "Complex polyrhythmic drums suitable for a sci-fi soundtrack"

MIDI Agent takes your text description, sends it to your chosen AI model (like those from OpenAI, Anthropic, Gemini, DeepSeek, or OpenRouter), and translates the AI's response into a usable MIDI clip on your track.

How to Generate Custom MIDI Clips with Natural Language Prompts Using MIDI Agent

Getting started is straightforward. MIDI Agent works seamlessly within your existing workflow.

Setting Up MIDI Agent

First, ensure you have MIDI Agent installed. As a VST3 plugin, it integrates directly into compatible Digital Audio Workstations (DAWs) like Ableton Live, Logic Pro, FL Studio, Cubase, and others. You'll load it onto a MIDI track just like any other instrument or MIDI effect. For detailed setup steps, you can always read the setup guide.

Crafting Your Prompt

This is where the magic happens. The key is to be descriptive. Think about:

  • Mood or Emotion: Happy, sad, energetic, mysterious?
  • Genre: Techno, jazz, classical, lo-fi hip hop?
  • Instrumentation: Piano chords, bassline, drum beat, string melody?
  • Musical Elements: Key signature, tempo (or feel like 'slow', 'fast'), time signature, complexity?
  • Structure: A 4-bar loop, an 8-bar verse progression?

Don't be afraid to experiment! Start simple and gradually add more detail.

Choosing Your AI Model

MIDI Agent doesn't rely on just one AI. It acts as a bridge, letting you connect to various powerful large language models (LLMs) via their APIs. This includes models from providers like:

  • OpenAI (e.g., GPT-4, GPT-3.5)
  • Anthropic (e.g., Claude models)
  • Google (e.g., Gemini models)
  • DeepSeek
  • And many more via OpenRouter

Different models can have distinct creative strengths. Some might excel at complex harmonies, others at catchy rhythms. Trying the same prompt with different models can yield fascinatingly varied results. You can see all compatible AI models on our features page.

Generating and Refining

Once you have your prompt and selected AI model, simply hit generate. MIDI Agent processes your request and places the resulting MIDI clip directly onto your DAW's timeline.

Not quite right? No problem. Tweak your prompt, maybe add more detail or change the requested style, and generate again. AI music composition is often an iterative process, and MIDI Agent makes this rapid iteration incredibly easy.

Why Use Natural Language for MIDI Generation?

Using text prompts to create MIDI offers several compelling advantages for musicians and producers:

  • Break Creative Blocks: Instantly generate starting points or variations when you feel stuck.
  • Accelerate Workflow: Quickly sketch out ideas for melodies, chords, or rhythms without manual input.
  • Explore New Styles: Easily experiment with genres or musical concepts outside your comfort zone. Just ask!
  • Enhance Accessibility: Provides a novel way to compose for those who find traditional input methods challenging.
  • Leverage Diverse AI Creativity: Tap into the unique "interpretations" of different AI models for unexpected musical ideas.

Tips for Effective Prompts

While AI is powerful, clear instructions yield better results. Try these tips:

  • Be Specific: Include key ("A minor"), tempo ("120 BPM" or "fast techno"), and instrumentation ("driving bassline").
  • Define Structure: Specify length ("4-bar loop", "8-bar chord progression") or section ("verse", "chorus").
  • Use Musical Terms: Words like "arpeggio," "syncopated," "walking bassline," or "pad chords" help the AI understand your intent. For a refresher on terms, basic music theory resources or the MIDI specification itself can be useful.
  • Experiment: Rephrase your request if the first result isn't perfect. Try synonyms or describe the desired feeling differently.
  • Iterate: Generate a basic idea, then refine it with follow-up prompts like "make that chord progression more complex" or "add a simple counter-melody to the previous clip."

Exploring Different AI Models Within MIDI Agent

One of MIDI Agent's unique strengths is its flexibility in connecting to various AI models. Think of models like Claude, Gemini, or GPT as different creative minds.

Feeding the exact same prompt (e.g., "jazzy piano chords in G major") to different models can produce noticeably different MIDI outputs. One might give you classic voicings, another might offer a more modern interpretation. This allows you to quickly audition different AI "takes" on your idea without leaving your DAW.

MIDI Agent puts the power of choice in your hands, turning your text descriptions into a diverse palette of musical possibilities.
