Suno has introduced MIDI file uploads to its Create tool, enabling Pro and Premier subscribers on desktop web to use musical data as a foundation for AI-generated compositions. By uploading .mid or .midi files, users provide specific note, timing, and velocity instructions while using text prompts to define instrumentation and style. This feature separates musical structure from recorded audio, allowing creators to re-orchestrate unfinished projects or explore new arrangements. While users can request high fidelity, the output should be treated as an interpretation rather than an exact reproduction of the original performance.
Suno introduced MIDI uploads to Create on November 4, 2026, giving musicians a way to start AI-generated songs from existing compositions and performances. Pro and Premier subscribers can upload .mid or .midi files in Simple Mode on desktop web, then describe the instrumentation, genre, mood and energy they want. The launch is documented in Suno’s announcement and its Create help article.
The key distinction is what goes into the upload: MIDI contains musical instructions, not recorded audio. A melody exported from a production session brings its notes and timing, but it does not bring the sound of the synthesizer that originally played it.
That separation makes this product update useful for unfinished sessions, score previews and classroom arrangements. It also creates a practical choice: decide which parts of the composition should remain fixed, then use the prompt to explain what Suno can change.
What MIDI Gives Suno, and What It Leaves Out
A MIDI file describes a musical performance through data such as pitch, timing, note duration and velocity. Velocity represents how hard a note is played. The file needs an instrument or sound-generating system to turn those instructions into something audible.
Suno’s help documentation summarizes the contents as “which notes play, when, how long and how hard.”
A piano melody stored as MIDI can therefore become the basis of a flute part, a synthesizer line or a string arrangement without carrying a piano recording into the process. The notes supply the musical material; the receiving system supplies the sound.
This differs from uploading a WAV or MP3. Recorded audio already contains an instrument’s tone, the performance and any effects captured in the recording. Suno’s announcement distinguishes MIDI input from its Remix and Cover workflows, which adapt uploaded audio.

The distinction matters for producers. If the valuable part of an old project is its bass line, MIDI separates that line from an outdated patch or effects chain. If the valuable part is a particular recorded texture, MIDI alone cannot carry it over.
My view is that this separation is the feature’s strongest practical benefit. It lets musicians decide on the musical material before committing to a sound, while still giving the AI more concrete instructions than a genre description.
How to Upload MIDI in Suno Create
The documented workflow starts in Create on desktop web, with a Pro or Premier subscription. Suno lists both .mid and .midi as accepted extensions.
Export the musical material. If your starting point is a DAW session or notation project, export the part or score you want to use as a MIDI file. The upload takes the exported MIDI, not the original project file.
Open Create and select Simple Mode. This is the mode specified in Suno’s help article.
Attach the MIDI file. Drag it onto the Create form, or use the file-selection control. Suno’s announcement describes choosing MIDI from the plus menu.
Write a prompt for the sound and treatment. Specify instruments, genre, mood and energy. Also explain whether Suno should closely follow the composition or develop it.
Select Create. Suno uses the uploaded musical structure alongside the text instructions to generate the result.
These steps follow Suno’s documented upload process. Menu wording may differ from the help page’s description, so drag-and-drop is another documented route if you cannot immediately find the MIDI option.
A useful preparation step is to decide what the file represents. A complete arrangement asks a different question from a four-bar melody. For an initial comparison, I’d use a clearly identifiable part: it makes it easier to judge whether the generated result retains the phrase you intended.
That is a workflow recommendation based on the input format, not a published Suno requirement.
Tell Suno What Must Stay and What Can Change
Suno says users can ask the model to follow the uploaded notes exactly, reinterpret them with different instruments, or develop a motif into new ideas. That makes the prompt a set of musical priorities, as well as a description of style.
A prompt that only says cinematic leaves several decisions open. It does not explain whether the melody should remain intact, whether the rhythm can change, or whether the file is merely inspiration.
The following are suggested prompt structures based on Suno’s documented controls:
For a close arrangement:Keep the uploaded melody’s pitches and rhythm. Use solo clarinet with a quiet string accompaniment and a restrained, intimate feel.
For a new instrumental treatment:Preserve the chord progression and lead phrase. Arrange them for electric piano, bass and brushed drums, with a relaxed late-night mood.
For creative development:Use the opening motif as the main theme. Develop it into an energetic electronic arrangement with contrasting sections.
Each example separates the musical material to retain from the sound to generate. Naming instruments also follows Suno’s own advice: the file supplies the musical instructions, while the prompt explains how to voice them.
Exact reproduction remains a vendor-described capability, not an independently verified result in the supplied evidence. The cited documentation provides no note-fidelity measurements or controller-by-controller support table. Treat a request for exact playback as something to check against the score or MIDI afterward, especially when timing or pitch accuracy matters.
Practical Uses for Producers, Composers and Teachers
Suno’s launch post highlights old sessions, work-in-progress scores and school music projects. Each benefits from the same mechanism, but the useful listening task differs.
Producers: Separate a Good Part From Its Old Sound
A saved MIDI performance can survive long after its original instrument choice stops being useful. Exporting that part gives Suno the musical phrase without requiring a recording of the original patch.
A producer could request a restrained acoustic arrangement of a synth melody, then try a more electronic treatment of the same material. Keeping the MIDI consistent makes instrumentation and arrangement the main variables.
I’d keep the initial prompts specific. Changing the melody, rhythm, genre and instrumentation at once makes it harder to tell which decision helped the idea.
Composers: Audition an Arrangement From a Score
A composer can export a work-in-progress score as MIDI and ask Suno for an orchestral or chamber treatment. Suno presents this as a way to hear compositions with generated instrumentation without first building a detailed sample-library arrangement.
The useful distinction is between auditioning an idea and confirming a faithful realization. A generated arrangement may help someone consider orchestral color or musical direction. Checking whether every written note survived is a separate task.
MIDI also has expressive limits. Suno acknowledges that the format cannot capture every articulation or timbral adjustment, even when carefully programmed.
Teachers: Change Instrumentation While Holding Notes Steady
Teachers and students can use an exported composition to explore how instrumentation changes the impression of a musical phrase. The same source material could be requested as a small ensemble or a larger arrangement.
For a lesson focused on orchestration, I’d keep the notes fixed in the prompt and change only the instrument request. That creates a clearer comparison. If the generation changes the melody too, the class is hearing two changes at once.
For composition development, the opposite approach can be useful: explicitly allow variations, then compare the new ideas with the original phrase.
Where Studio Editing and v6-wild Fit
Suno’s Create help article also points to Studio for MIDI editing. It lists quantizing notes, moving them slightly off the grid, and changing the key or scale as available operations.
Those controls affect different layers of the music:
Quantizing aligns note timing more closely with a rhythmic grid.
Moving notes off the grid adjusts their placement for a less rigid feel.
Changing key or scale alters pitch organization.
Changing the prompt’s instrumentation asks for a different sound or arrangement without requiring the same kind of note edit.
For musicians whose problem is an uneven source performance, editing the MIDI is a more direct intervention than repeatedly changing style words. That follows from where the information lives: timing is in the file, while the desired instrumental treatment is described in the prompt.
There is also a product-access distinction worth checking. Unite.AI’s launch report says the new Create workflow uses v6-wild in Simple Create. It separately describes Studio 2.0, released on August 13, 2026, as adding MIDI import, recording and editing, with Premier availability at that release.
Those version and Studio launch details come from secondary reporting. The primary Create help page confirms Pro and Premier access to this upload feature, but its mention of Studio editing should not be read as a promise that every Create subscriber receives every Studio capability.
For a practical first pass, keep the workflow simple: upload the MIDI, specify the instruments, state what must remain unchanged, and listen against the source. If the composition needs editing, change the musical data. If the sound is wrong, revise the prompt.
