Song to Brass Section MIDI
Turn a song into brass section MIDI you can edit. Upload MP3, WAV, M4A or FLAC, leave brass section selected, check the stack on the piano roll, then drop the .mid into your DAW.
Hear the brass, see the section MIDI
Play the source beside the piano roll. Stacked hits and pads are easier to trust when you hear the same beat before export.

Reading the MIDI…
Brass section MIDI for the stack you heard
Section hard mask
This landing opens Audio to MIDI with brass section already chosen. MIDI targets the choir-style stack instead of a single solo trumpet.
Sketch MIDI to split in your DAW
Download the unquantized .mid and break voicings across trumpet, horn, and trombone tracks — a section MIDI you can explode and revoice in your DAW.
When the brass is buried
Isolate brass with Stem Splitter first if vocals dominate, then upload that stem here.
Solo brass pages exist
For a single trumpet, trombone, horn, or tuba line, use that instrument's MIDI landing instead.
How to turn a song into brass section MIDI
From the brass take you have to a .mid sketch you can split.
- 1
Upload up to 10 minutes of audio
MP3, WAV, M4A or FLAC — horn section hit, pop brass stack, or a mix where brass is clear. Or pick from My Music.
- 2
Keep brass section selected
This page already chooses brass section. Add another part only if it should share the MIDI.
- 3
Check the stack on the piano roll
Scrub hits and pads against the recording before export.
- 4
Download .mid and split in the DAW
Take the transcription MIDI into Ableton, Logic, or FL Studio. Revoice across instruments there.
Brass section MIDI you can export
When the roll looks right, take the .mid into your DAW. Printable parts are the sheet sibling's job.
- 01
MIDI (.mid)
Preferred DAW import — History surfaces the unquantized transcription MIDI first. Drop it into Ableton, Logic, FL Studio, or similar.
- 02
Revoice stabs across your brass choir
Import the section .mid, then revoice stabs and split parts across your brass choir.
Clearer brass audio, cleaner section MIDI
If the brass is buried under vocals, isolate it first — then convert that stem.
Start from a brass-forward take
A clear section balance beats a distant, reverb-washed mix.
Isolate when the mix is busy
Use Stem Splitter for brass, upload the stem here, or leave Auto on if the stack is already obvious.
Revoice stabs across the choir
Revoice stabs and split parts across your brass choir for a powerful section hit.
Arrangers who needed brass MIDI, not another stab preset
“Pop brass stack became MIDI I could explode into three tracks.”
“Hard mask kept strings out of the brass clip. Hits stayed readable.”
“Dropped the MIDI into Ableton, then I revoiced the stab. Faster than starting empty.”
