Song to Double Bass MIDI
Turn a song into double bass MIDI you can edit. Upload MP3, WAV, M4A or FLAC, leave double bass selected, check the orchestral bass line on the piano roll, then drop the .mid into your DAW.
Hear the double bass, see the MIDI
Play the source beside the piano roll. Low orchestral notes are easier to trust when you hear the same beat before export.

Reading the MIDI…
Double bass MIDI for the orchestral line you heard
Contrabass hard mask
This landing opens Audio to MIDI with double bass already chosen. MIDI stays on the orchestral bass line — not electric bass.
Low string pitches for a DAW
Download the unquantized .mid for a contrabass library. Set octaves and timing so the orchestral bass holds the floor.
When the bass is buried
Isolate double bass with Stem Splitter first if the orchestra is dense, then upload that stem here.
Not electric bass or upright jazz page
Plugged-in pocket lines use electric bass. Jazz upright often fits the acoustic bass landing. This page is orchestral double bass.
How to turn a song into double bass MIDI
From the contrabass take you have to a .mid you can rewrite.
- 1
Upload up to 10 minutes of audio
MP3, WAV, M4A or FLAC — orchestral excerpt or mix where the double bass is clear. Or pick from My Music.
- 2
Keep double bass selected
This page already chooses contrabass. Add another part only if it should share the MIDI.
- 3
Check low notes on the piano roll
Scrub octave placement against the recording before export.
- 4
Download .mid and refine in the DAW
Take the transcription MIDI into Ableton, Logic, or FL Studio.
Double bass MIDI you can export

MIDI (.mid)
Preferred DAW import — History surfaces the unquantized transcription MIDI first. Drop it into Ableton, Logic, FL Studio, or similar.
- 02
Anchor the low end on contrabass samples
Drop the .mid on a contrabass library, then set octaves and timing so the orchestral bass line holds the floor.
Clearer double bass audio, cleaner bass MIDI
If the contrabass is buried under celli, isolate it first — then convert that stem.
Start from a bass-forward take
A clear low-end balance beats a distant hall mix.
Isolate when the mix is busy
Use Stem Splitter for double bass, upload the stem here, or leave Auto on if the line is already obvious.
Confirm octaves on the low line
Confirm octaves and timing so the orchestral bass line holds the floor.
Orchestrators who needed double bass MIDI, not synth bass
“Orchestral bass line became MIDI I could mock up before rewriting the score.”
“Glad this stayed separate from electric bass — register finally matched.”
“Dropped the MIDI into Cubase, then locked a few octave jumps. Ready for the contrabass part.”
