Turn Separated Instruments into Editable MIDI
Choose an instrument stem from a completed multi-stem separation and convert its performance into structured pitch, timing, and velocity data.
Move from Generated Audio to Hands-On Production
MIDI captures a performance as editable note events rather than recorded sound, giving you a practical starting point for arranging, transcription, and study.
Re-orchestrate with New Sounds
Import the note data into a DAW and assign a different virtual instrument without being tied to the original stem's timbre.
Study Notes and Rhythm
Inspect detected pitch, note timing, duration, and velocity when transcribing melodies, bass lines, keyboard parts, or drum patterns.
Build New Arrangements
Edit, quantize, transpose, duplicate, or combine the extracted performance with your own instruments and song structure.
Choose a Clear Stem for a More Useful Transcription
MIDI generation analyzes a separated instrument track. Source separation quality and musical complexity directly affect the detected notes.
Complete Multi-Stem Separation First
The MIDI source must come from a completed Vocal Separation task created with multi-stem separation, not from an original mixed song.
Select One Instrument Stem
Choose the isolated drums, bass, guitar, keyboard, strings, brass, woodwinds, percussion, synth, or other available stem you want to transcribe.
Understand the Result
Each detected note contains a MIDI pitch number, start and end time in seconds, and velocity value representing playing intensity.
Expect Better Results from Clean Parts
Clear, well-separated audio with a distinct instrument part is generally easier to analyze than dense, overlapping, or heavily processed material.
Add Your Own Instrument Sound
MIDI does not preserve the source recording or timbre. Load a virtual instrument in your music software to hear and shape the notes.
Review and Refine the Notes
Instrument detection is not guaranteed to be complete. Check the transcription and correct missed, extra, or imprecise notes in your DAW.
How to Generate MIDI from a Stem
Separate the song into instruments, select the clearest stem, and convert its performance into editable note data.
Separate the Instruments
Open Vocal Separation and use multi-stem separation to extract individual instrument tracks from one of your songs.
Choose a Stem
Return to the MIDI Generator and select the separated instrument you want to transcribe. Only eligible completed stems are listed.
Generate and Edit
Generate the structured note data, then use it as a transcription reference or continue editing it in your music-production workflow.
MIDI Generator FAQ
Understand what MIDI contains, which sources are supported, and what to expect from an audio transcription.
What is MIDI?
MIDI is performance data rather than recorded audio. It represents notes and their pitch, timing, duration, and velocity so they can be edited or played with software instruments.
Which source tracks can I select?
This page lists instrument stems from completed multi-stem Vocal Separation tasks. Original songs and basic two-track vocal/accompaniment results are not eligible.
Does MIDI keep the original instrument sound?
No. MIDI describes the performance but does not contain the original audio or timbre. The sound comes from the instrument or synthesizer you assign later.
Which instruments can be detected?
Detection can include drums, bass, guitar, keyboards, strings, brass, woodwinds, percussion, synths, and other separated parts, depending on the source audio.
Will every note be transcribed perfectly?
Not necessarily. Accuracy depends on separation quality and the complexity of the performance. Treat the result as an editable starting point and review it before production use.
Turn an Instrument Performance into Editable Data
Start with a clean separated stem and create note data you can analyze, rearrange, and voice with your own instruments.
