The Complete Guide to Creating Royalty-Free BGM with AI Composition & MIDI [2025]

AI Composition Tools Now Let Anyone Create Legally Clear BGM

"I can never find free BGM that matches my vision" or "The licensing terms are so confusing I don't know what I can actually use" — more and more creators are running into these exact problems. In 2025, a new workflow has become genuinely practical: generate MIDI with an AI composition tool, arrange it yourself, and walk away with original, copyright-clear BGM.

This guide walks you through the entire process: using an AI composition tool trained on properly licensed data to build commercially usable original BGM from scratch. We'll cover everything from generating the MIDI to finishing it in a browser-based DAW — explained clearly enough for complete beginners.

Breaking News: Amadeus Code Launches AI MIDI Generator "MusicTGA"

In 2025, music technology company Amadeus Code released a new AI composition app called MusicTGA. Its defining feature: it was trained exclusively on properly licensed music data.

Most AI composition tools are vague about the rights status of their training data, leaving users anxious about questions like "Can I use this commercially?" or "Am I infringing someone's copyright?" MusicTGA addresses this directly — the MIDI files it generates can be used in commercial projects (always check the latest Terms of Service for specifics).

How MusicTGA Tackles the AI Music Rights Problem

Copyright questions around AI-generated content are being debated around the world. In the US, the Copyright Office continues to update its guidance on AI-generated works, and similar discussions are ongoing in other countries. Against this backdrop, a tool that clears the rights question at the training data level is a major development for music producers and video creators alike.

• Trained on licensed data → No risk of copyright infringement during training
• MIDI output → When you arrange the output yourself, the copyright in your arrangement belongs to you
• Built for commercial use → Suitable for YouTube monetization, game soundtracks, advertising music, and more

What Does "Legally Clear" BGM Actually Mean? A Beginner's Breakdown

BGM involves three main categories of rights.

① Copyright (Composition, Arrangement, and Lyrics)

These are the rights held by whoever created the music. Copyright protection lasts for decades after the creator's death. The copyright status of AI-generated music is still being debated, but the prevailing view is that when a human uses AI as a tool and makes creative decisions to bring a piece to completion, copyright protection is likely to apply.

② Neighboring Rights (Performers and Record Producers)

These rights belong to performing artists and record labels. When you trigger a MIDI file yourself using a software instrument and record the output, you hold these rights — so there's no issue here.

③ Rights Related to Training Data (A New Concern)

What music an AI was trained on can potentially affect the rights status of what it generates. Tools like MusicTGA, which are designed from the ground up to use only licensed training data, represent one clear answer to this concern.

How to Create Copyright-Free BGM with AI-Generated MIDI: Step-by-Step

Here's a practical walkthrough of the full workflow — from AI-generated MIDI to finished, original BGM.

Step 1: Generate MIDI with an AI Composition Tool

Start by using MusicTGA (or one of the alternatives covered below) to generate a MIDI file.

1. Open MusicTGA and choose a genre and mood (upbeat, calm, tense, etc.)
2. Set a tempo and key if you have something specific in mind — or leave it up to the AI
3. Click Generate and download the MIDI file (.mid)

Pro tip: Generate several variations at once and pick your favorite. Think of the AI's MIDI as raw material — the next steps are where you make it your own.

Step 2: Import the MIDI into a DAW

Load the MIDI file into a DAW for editing. LA Studio (a free, browser-based DAW) requires no installation — just drag and drop your MIDI file directly into the editor.

1. Open LA Studio in your browser (no sign-up required, completely free)
2. Drag and drop your downloaded MIDI file into the editor window
3. The MIDI will appear as a region on a track
4. Double-click the region to open the piano roll for note editing

Step 3: Arrange the MIDI in the Piano Roll

Rather than using the AI's MIDI as-is, editing and arranging it yourself is key. This is what transforms it into your own creative work.

• Add or delete notes: Rewrite anything that doesn't work for you
• Change the chord progression: The same melody can feel completely different over different chords
• Adjust the rhythm: Shift note timings to add groove and feel
• Add instrument parts: Layer in a bassline, drums, chord pads, and more

LA Studio's AI note prediction feature (press Tab while editing) suggests the next note as you compose, which is great for sparking arrangement ideas when you're stuck.

Step 4: Choose Instruments and Bring It to Life

MIDI is just performance data — you need an instrument to make it sound like music. LA Studio comes with a solid lineup of built-in virtual instruments:

• Salamander Grand Piano: Realistic acoustic grand piano
• Sonatina: Full orchestral instrument suite
• Surge XT: Professional-grade synthesizer
• Dexed: Classic FM synthesis (Yamaha DX7 compatible)
• Vital: Modern wavetable synthesizer

Pick an instrument that fits your genre, assign it to your MIDI track, and you've got realistic-sounding playback.

Step 5: Mix and Add Effects

Once your tracks are arranged, use the mixer to balance everything.

1. Adjust volume and panning (stereo placement) for each track
2. Add reverb to create a sense of space
3. Use EQ to cut unwanted frequencies and boost what you want to emphasize
4. Apply compression to even out the dynamics
5. Add a limiter on the master track to control overall volume

LA Studio includes over 20 built-in effects — reverb, delay, EQ, compression, chorus, distortion, and more — so you can achieve professional-quality sound without spending a dime.

Step 6: Export as Audio

When you're happy with the result, export it as WAV or MP3. You now have a finished, legally clear, original BGM track — created by you, powered by AI.

3 Things to Verify Before Using AI BGM Commercially

No matter which AI tool you use, always check these three things before going commercial.

① Read the Current Terms of Service for Each Tool

AI service terms change frequently. Even if a tool says "commercial use allowed," there may be conditions tied to your subscription tier or specific use case. Always check the official Terms of Service page right before you use anything commercially.

② Document Your Creative Involvement

Rather than using AI-generated MIDI straight out of the box, keeping a record of your editing and arrangement decisions strengthens your claim to copyright ownership. Save your project files and version history.

③ Check the Rights Status of Your Sound Sources

Even if the MIDI data itself is clear, the sound library or sample pack you use to play it back may have commercial use restrictions. The instruments built into LA Studio are generally cleared for commercial use, but always verify the license if you bring in third-party sounds.

Where AI-Composed BGM Shines: Perfect Use Cases

• YouTube video background music: Produce original BGM for monetized content at minimal cost
• Indie game soundtracks: Generate large volumes of looping BGM by genre and tempo, then customize
• Podcast and radio jingles: Quickly create short, branded music beds
• Corporate and presentation videos: Avoid licensing fees with original music tailored to your project
• Music theory practice: Analyze AI-generated chord progressions and melodies to sharpen your arrangement skills

Frequently Asked Questions

Q. Does AI-generated MIDI have copyright protection?

A. Currently, the prevailing view in most countries is that content generated entirely autonomously by AI does not qualify for copyright protection. However, when a human is creatively involved — setting parameters, making selections, and editing the output — copyright in those contributions is likely to apply. The takeaway: actively use AI as a tool, then make the music your own through arrangement and editing.

Q. What's the difference between a rights-cleared AI composition tool and one that isn't?

A. The key difference is how the training data was sourced. An AI trained by scraping music from the internet without permission carries different legal risks than one trained exclusively on licensed material. Tools like MusicTGA, which are transparent about using only properly licensed training data, give you significantly more peace of mind.

Q. What's the difference between MIDI and an audio file?

A. MIDI is performance instruction data — it tells a virtual instrument which notes to play, when, and how hard. On its own, it makes no sound. You need to pair it with a virtual instrument or sound library to hear anything. MP3 and WAV, by contrast, are recordings of actual audio waveforms. The advantage of MIDI is total flexibility after the fact — you can change sounds, tempo, and notes at any time, making it far easier to revise and arrange.

Q. Can I monetize YouTube videos using BGM I made with AI?

A. Yes, if the AI tool's Terms of Service permit commercial use and you've arranged the output yourself. That said, false Content ID claims can still occur — especially with AI tools whose training data includes existing commercial music. Using a tool like MusicTGA, which was trained on licensed data only, significantly reduces this risk.

Q. Can I make BGM with AI even if I have no music theory background?

A. Absolutely. AI composition tools handle the heavy lifting — just pick a genre and mood and they'll generate a MIDI for you. That said, learning basic DAW operation and a little music theory (chords, scales) will take your results to a noticeably higher level. A browser-based DAW like LA Studio has an intuitive interface that's friendly for beginners, making it a great place to learn as you create.

Conclusion: AI-Composed MIDI Is the New Standard for Rights-Clear BGM

The arrival of tools like Amadeus Code's MusicTGA — trained from the ground up on properly licensed music — marks a real step forward for commercial creators who need BGM they can use with confidence.

The mindset shift that matters most: treat AI not as something that hands you a finished product, but as a creative starting kit. Generate a MIDI, shape it with your own arrangement, and polish it with instruments and effects. That process is what turns an AI output into a track that's genuinely yours.

If you want to go from raw MIDI to finished, exported audio without leaving your browser, give LA Studio a try — it's free, requires no installation, and has everything you need: a piano roll, virtual instruments, effects, and a mixer. Drag in your MIDI, arrange it, and export your final audio, all in one place.
