AI song generator with stems and MIDI

Published October 2026

Most AI song generators hand you a finished recording. Doseedo hands you the session the song was built in: a Logic Pro or Ableton Live project with every part on its own track, as audio and as the MIDI it was played from, at the song's tempo. Start from a sentence in the studio chat, or from an AI agent such as Claude or ChatGPT. Either way, what you download is a project you open in your DAW and keep working on, not a folder of WAVs to line up by hand.

What comes back

A real run from 29 October 2026. The request was "a 45-second country song", and this is the project that came back:

Country song from a prompt.logicx     110 bpm · 4/4 · F major · 44.1 kHz
  audio  Drums           45.6 s   272 of 275 written hits heard
  audio  Bass            45.6 s    41 of 41 notes heard
  audio  Rhythm Guitar   45.6 s    74 of 78 strums heard
  audio  Lead Guitar     45.6 s    44 of 44 notes heard
  MIDI   Drums           321 notes
  MIDI   Bass             41 notes
  MIDI   Rhythm Guitar   240 notes
  MIDI   Lead Guitar      44 notes

The same parts came back as an Ableton Live Set as well: 110 bpm, the same eight tracks, all 646 notes, and a clean pass through our .als lint against Live's load rules. The mix came back separately, as a WAV at −12.9 LUFS with a true peak of −1.0 dB.

The "heard" figures are the render's own receipt. After every render the audio is transcribed and checked against the written notes, so a part that drops notes says so instead of hiding in the mix. In this run the first drum take dropped 53 of 259 snare hits, mostly the ghost notes. The receipt flagged it, the drums were re-rendered on the sampled kit (which plays every written hit), and the new take came back at 272 of 275.

Stems that were never mixed together

Most prompt-to-song generators make one mixed recording first. Stems, where they are offered, are split out of that recording afterwards, so every stem carries a little of the others, and MIDI, where it is offered, is transcribed back out of the stems. Here the order is reversed. The notes come first, each part is rendered on its own from its own notes, and the mix is made from those renders. A stem has nothing else in it because nothing else was ever in it, and the MIDI track is not a transcription: it is the part the audio was played from.

Two ways in

From the browser.

  1. Open the studio and the chat beside the timeline ("ask me about your session").
  2. Ask for the song in plain words, with a genre and, if you like, a length, a key, a tempo and the band: "make a 2-minute country song in G at 96 bpm", "a lo-fi hip hop track with Rhodes and upright bass", "a romantic string quartet piece". Without a length you get about two minutes.
  3. The song engine writes the whole arrangement in one pass (form, chords, and every part across the form), and each part lands on its own track as MIDI and is played by an instrument model, at full length. A song is sung unless you ask for an instrumental: the engine writes the melody and the chat writes one lyric line per phrase.
  4. Change a part by asking, right after it lands: "busier", "simpler", "swing it", "an octave lower", "make the drums 16ths". Or edit the notes yourself.
  5. Export from the Export / Share panel as a Logic Pro, Ableton Live, Pro Tools, FL Studio or REAPER project.

The studio opens without an account. The chat and the renders need a free one: type your request signed out and it is kept, and it sends itself once you have signed in.

From an AI agent.

The same result is one conversation away in any AI client that speaks MCP (Claude, ChatGPT, Cursor, Gemini CLI, Codex). Connect https://api.doseedo.com/mcp and ask for the song. The agent follows the server's own compose-piece recipe: it writes every part as notes, doseedo_render_score plays them (one stem per part, each with a receipt saying whether it played the written notes), doseedo_mix mixes them, and doseedo_session_from_stems returns the Logic or Ableton project with every part as audio and MIDI, at the mix's levels and pans. The agent does the composing, so the key, the tempo and the form are exactly what it wrote.

The Claude guide walks through a piece Claude wrote note by note, and the ChatGPT guide covers the same flow in ChatGPT.

What the song engine writes

The studio chat does not ask a language model to guess notes. A request for a song goes to an arrangement engine with 45 genre packs (trap, country, house, bossa nova, K-pop, afrobeats, orchestral and more), each describing the genre's forms, chord habits, grooves, bass styles and comping. This is what it wrote for the country song, in under a second:

style   country          tempo 110 bpm (the pack's range is 80–140)
key     F major          20 bars, 43.6 s
form    intro 2 · verse 8 · chorus 4 · chorus 4 · outro 2
chords  F F/A | Bb | F | F5 | Bb | C7 | F | F7 F7/A | Bb | C7 |
        F | Bb | C | F | F | Bb | C | F | C | F
parts   Drums           321 hits   fills into bars 3, 11, 15, 19
        Bass             41 notes  electric bass
        Rhythm Guitar   240 notes  acoustic, strummed chords
        Lead Guitar      44 notes  acoustic, enters with the verse

Because the parts start as notes, the key, the tempo and the form are facts about the song rather than hopes: you can name them in the request, and the project's tempo is the song's tempo, so nothing drifts against the grid. The text-to-MIDI guide shows a 60-second trap song from the same engine.

What it costs and how long it takes

Renders draw on the account's monthly credit pool: ten credits per 30-second window, for each group of up to six parts (the takes in a batch cost nothing extra). Mixing and building the project cost no credits. A free account comes with 120 credits a month and Pro with 2,000. The country song above cost 40: 20 for the four parts and 20 for re-rendering the drums.

Wall-clock time for the country song, queue included: 51 seconds to render the four parts, 82 seconds to re-render the drums, 23 seconds to mix and 30 seconds to build the Logic project. The Ableton build took 23 seconds more.

Already have a song?

If the song exists already, made in Suno or recorded by a band, the route runs the other way: the mix is separated into stems, each stem is transcribed to MIDI, and the tempo map and chords are detected, all into one project. That is audio to session. The guides for Suno to Logic Pro, Suno to Ableton and Suno to MIDI cover the cases people ask about most, and remixing a song covers what to do with the parts.

FAQ

Is there an AI music generator that exports stems and MIDI?

Yes. Doseedo builds a song as separate parts, renders each one on its own, and exports a Logic Pro or Ableton Live project with every part as an audio track and as the MIDI it was played from. The studio also exports to Pro Tools, FL Studio and REAPER.

Are the stems separated from a mix?

No. Each part is rendered on its own from its own notes, and the mix is built from those renders, so a stem has no bleed from the others. Separation is only used when you bring an existing song.

Can I choose the key and the tempo?

Yes. Name them in the request ("in D minor at 92 bpm") and the song is written in that key at that tempo. An AI agent writing the notes itself sets them exactly.

Does it make vocals?

In the studio chat a song is sung unless you ask for an instrumental: the engine writes the melody and the chat writes one lyric line per phrase. You can also name the band, for example "with Rhodes, upright bass and brushes".

How much does it cost?

Renders cost ten credits per 30-second window for each group of up to six parts; mixing and building the project are free. A free account has 120 credits a month. The 45-second, four-part country song on this page cost 40.
