Split & rebuild
Any recording, back to editable tracks.
Drop a song you own. Koprod separates it, finds its tempo, key and sections, and rebuilds the parts as notes you can change.
Listen
Made in Koprod.
Every sound here came out of the app.

How it works
Four steps, a minute or two.
Drop it
A recording you own or may use, up to 12 minutes, on the prompt box.
It separates
Vocals, drums, bass and everything else, on your computer.
It listens
Tempo, downbeat, key and sections.
It rebuilds
Drums, bass and the rest come back as MIDI on Koprod instruments. The vocal stays as audio.
Nothing is uploaded
Separation and note detection run on your computer. The stems and the original mix sit under the new song, muted, for reference.
Only what you may use
Split & rebuild is for recordings you own or have permission to use. Koprod asks you to confirm it before it starts.
More to try.
Open any part, move any note
Every track is real notes on real instruments. Drag one and hear the song change.
Hum it, get a part
Sing, hum or beatbox over your song. Your voice becomes notes on any instrument.
Describe the song you hear
Name a style, a tempo, a key, or just a mood. Koprod writes every part in about a minute.
What can I split?
A recording you own or may use: your demo, a rehearsal, a track you produced. At least 5 seconds, up to 12 minutes.
Is my recording uploaded?
No. Separation (Spleeter) and note detection (Basic Pitch) run on your computer.
How long does it take?
A minute or two for a three-minute song.
What do I get?
A new song: drums, bass and the other parts as MIDI on Koprod instruments, the vocal as audio, and the stems and original mix underneath, muted.
Will it sound like the original?
Not exactly. The parts are played again on Koprod’s instruments, so it sounds like a new production of the same song, one you can change note by note.
