Exporting from Suno

Before using this tool, you need to export your song from Suno with stems and (optionally) MIDI.

How to export

  1. Open your song on suno.ai
  2. Click the download button and select Stems — this downloads a ZIP containing individually numbered WAV files for each instrument
  3. If available, download the MIDI file for the same song (Suno Studio can export MIDI derived from stems — useful for recreating melodies or drum patterns with your own instruments)
  4. Create a project directory and unzip/move all files into it:
1
2
3
4
mkdir ~/suno-exports/my-song
# Unzip the stems ZIP into this directory
# Add the .mid files too, if available — at the top level or in any
# subfolder (e.g. midi/); MIDI is discovered recursively

What Suno exports

Suno exports tempo-locked WAV stems — all stems share the same BPM, sample rate, and frame count. This means:

  • Stems stay aligned to the song's BPM when imported into a DAW
  • They line up on the grid without manual adjustment
  • Minimal warping is required in Ableton

The preprocessor verifies this: it checks that all stems have consistent sample rates and frame counts, and warns if anything is off.

MIDI is optional

Not every Suno export includes MIDI. When available, it's a transcription (not the original sequence), so it may contain wrong notes or phantom chords — the preprocessor's harmonic MIDI repair feature can help clean these up.

my-song/
├── 0 Song Name.wav          # Full mix (track 0)
├── 1 FX.wav                 # FX stem
├── 2 Synth.wav              # Synth stem
├── 3 Percussion.wav         # Percussion stem
├── 4 Bass.wav               # Bass stem
├── 5 Drums.wav              # Drums stem
├── 6 Backing_Vocals.wav     # Backing vocals stem
├── 7 Vocals.wav             # Vocals stem
├── 8 sample.wav             # Sample stem
└── Song Name.mid            # MIDI file (optional)

MIDI files don't have to sit at the top level — subdirectories are scanned recursively, so a layout like this works too:

1

my-song/
├── 0 Song Name.wav
├── 1 Drums.wav
└── midi/
    ├── Song Name (Drums).mid
    └── Song Name (Bass).mid

Output folders (processed/) and hidden directories are ignored, and a top-level MIDI file wins over a subfolder file with the same name.

File naming details

  • WAV files are numbered 0–8 and prefixed with the stem type
  • Track 0 is always the full mix; tracks 1–8 are the individual stems
  • The MIDI file has no number prefix — it matches the song name, often with the stem in parentheses (e.g. Song Name (Drums).mid)
  • All WAVs should be 48kHz stereo float with identical frame counts (tempo-locked)
  • Not all stems may be present in every export (e.g. some songs have no sample or FX stem) — the preprocessor handles missing stems gracefully
