AI MIDI Generator: From Text to an Online MIDI Editor

The new AI MIDI generator turns a written musical idea into an editable MIDI arrangement. Describe a piano melody, a chord progression, a bass line or a beat, then work on the result in the built-in online MIDI editor. You can also ask for another version in the conversation, without starting your description from scratch.

Limited-time launch offer: free accounts can use MIDI generation too. Sign in and use your available credits: each generation costs 5 credits, including a follow-up request that creates another version. Failed generations are refunded. “Free-account access” means you do not need a paid membership during this offer; it does not mean unlimited generation or zero credit cost. Check free credit opportunities and your credit balance before starting.

What does an AI MIDI generator create?

A MIDI file contains musical instructions: notes, their timing and duration, velocities and instrument assignments. It is useful when you want to change the composition after generation. You can move notes, adjust a phrase or choose another instrument in an editor or your digital audio workstation (DAW).

This text-to-MIDI tool composes from your description. It does not turn a written prompt into a finished vocal recording. If you already have eligible instrumental audio to transcribe, use Music to MIDI. For a complete generated audio song, start with the AI music generator.

How to generate MIDI from text

1. Describe the musical idea

Open MIDI Generator and write a specific prompt. Include the instruments, mood, key or chord progression, rhythmic feel and the role of each part. You can write naturally; you do not need to supply a technical note format.

For example:

Create a gentle piano melody in C major with a separate accompaniment track. Use simple C–Am–F–G chords, leave space between phrases, and resolve the final melody note to C.

A shorter prompt works too, but clear musical constraints make it easier to judge and improve the output. A generated result still needs listening and review; a detailed prompt does not guarantee every note will match your intention.

2. Set the tempo and length

Choose a tempo from 40 to 240 BPM and a length of 4, 8 or 16 bars. The generator currently uses 4/4. These controls define the requested arrangement length and tempo, so use them alongside your prompt.

Click Send to create a version. Each submission costs 5 credits. The conversation shows your request, generation progress and the resulting MIDI card.

3. Play the result in the online piano roll

Once generation finishes, the MIDI loads automatically into the editor beside the conversation on desktop. Click Play to listen, inspect the tracks and review the notes in the piano roll online. On a small screen, switch between the Conversation and Editor tabs; the current arrangement stays loaded.

If you searched for a piano roll maker, this is the practical workflow: generate a starting arrangement, then shape its notes visually instead of accepting an audio recording you cannot rearrange note by note.

4. Ask for a revision

Try a follow-up such as:

Keep the accompaniment, make the melody less busy, and lower the bass by one octave.

The next generation uses the selected generated version as its starting context. It creates a new MIDI result for another 5 credits. Your earlier requests and result cards remain visible during the current page session, so you can compare versions and use Load to return to an earlier generation.

Manual changes made inside the editor are not automatically included in the next AI request. Export those edits before loading another generated version if you want to keep them. Refreshing the page clears the current conversation view; successfully generated files remain available in your Library.

Edit MIDI online: adjust the notes, then export

The MIDI editor online lets you review and change the musical arrangement directly in your browser. Use the piano roll to adjust note pitch, position and length, listen to individual parts, and refine the performance before taking it into your DAW.

There are two different download paths:

• Download original MIDI on a conversation card saves that generated version.
• Export in the editor saves the arrangement with your manual edits.

Loading a historical result replaces the arrangement currently open in the editor. Export a manually edited version first if you want to keep both. Opening the standalone online MIDI editor is also useful when you already have a .mid file and simply want to edit MIDI online.

Prompt examples for piano, bass and drums

Piano melody and chords: “Write an expressive piano melody in A minor with a separate soft chord track. Keep the first phrase sparse and give the second phrase a gentle rise.”

Lo-fi groove: “Create a relaxed lo-fi loop with electric piano chords, warm bass and restrained drums. Leave room for a lead part and keep the rhythm easy to loop.”

Cinematic strings: “Create a short cinematic arrangement with sustained low strings and a simple violin motif. Build gradually and end on a stable chord.”

Start with a small number of clearly named parts. After listening, change one aspect at a time: rhythm, melody, register or instrumentation. This makes revisions easier to compare.

Frequently asked questions

Can free users generate MIDI?

Yes. During the limited-time launch offer, signed-in free accounts can use the feature with sufficient credits. Every generation, including an AI revision, costs 5 credits. Failed generations are refunded. No end date is announced here; availability may change after the launch offer.

Is this an online MIDI editor or an AI MIDI generator?

It includes both: the generator creates MIDI from text, and the embedded editor lets you play, edit and export the result. You can use the online MIDI editor separately for existing MIDI files.

Can I change an existing recording into MIDI?

Use Music to MIDI for the eligible instrumental-audio workflow. Text-to-MIDI creates a composition from a prompt; audio transcription is a separate feature with its own availability and cost.

Will the file sound identical in every music app?

No. MIDI stores performance instructions rather than a finished audio waveform. The instrument sounds used by your editor or DAW affect playback. Listen again after importing the file into another application.

Can I download the MIDI for my DAW?

Yes. Download a generated version from its conversation card, or export your manually edited arrangement from the editor. The result is a .mid file you can import into a DAW that supports MIDI.
