Stem separation
How to split a mixed audio track into separate stems on Morphic, such as vocals and instrumental, by asking Copilot.
Stem separation on Morphic splits one mixed audio file into separate tracks, called stems, also known as a vocal remover or karaoke maker. You attach a track in Copilot and ask for the split, and each stem comes back as its own audio file, the same length as the source. There are two splits, and two stems is the default:
| Split | Stems you get | Ask for it with |
|---|---|---|
| Two stems (default) | Vocals, instrumental | "Remove the vocals", "Make an instrumental", "Give me the a cappella" |
| Six stems | Vocals, drums, bass, guitar, piano, other | "Split this into every instrument", "Give me the drums and bass separately" |
When to use it
- Lay a song under a scene without the singing
- Lift a vocal out of a finished mix for a remix or a new arrangement
- Keep one instrument, such as the piano, and drop the rest
- Work from a final mix when you have no session files
Split a track
- Open Copilot
- Attach the audio file with the paperclip
- Ask for the split, for example "Split this into vocals and instrumental"
- The stems appear in the chat as separate audio files
To split the sound of a video, attach the video and ask the same way. Copilot pulls its audio out first, then splits it.

Tips
- It splits music into parts. It does not remove background noise from a voice recording
- Split a short section first when you only need part of a song. Trim it, then split the part you will use
- Bring the stems into Compose to mix them back against your picture
That's how you use Stem separation on Morphic. Reach for it when you have the finished mix and need one part of it on its own.
