Stem Generation creates new instrumental tracks from your own audio, in your key, your tempo, and your feel. Record a guitar part and generate the drums and bass to go with it. Every part is shaped by what you played, so the result sounds like your song, not a sample library.
Let your ideas lead
Stem Generation: Tracks that respond to your sound
Play a riff, hum a melody, or drag in your beat. Moises generates an instrument that follows your timing, chords, and vibe.


How it works
From One idea to a full arrangement
Start with your idea
Record or upload your audio: a guitar riff, a chord loop, a drum groove. That's all it takes.
Choose an instrument and dial in the style
Pick Drums, Bass, Guitar, Keys, Strings, or Others. Genre presets shape the sound, and expressiveness controls take it from subtle to dynamic.
Generate, refine, and build
Stem Generation creates a new track that locks in with what's already there. Regenerate any part, keep what works, and layer instruments until the arrangement is complete.
WHAT IS STEM GENERATION?
New tracks, created from what you play

Stem Generation
You play your idea. Moises creates new tracks around it.

Stem Separation
You upload a finished song. AI splits the existing tracks apart.
Built to keep you playing
Genre presets, per-stem control, and smart section fills, designed so the session never stalls.

Shape your track in seconds
Genre presets for drums, bass, guitar, and more. Pick a style in one tap, hear it in place, and move on to the next part. Funk, trap, R&B, rock overdrive: the styles are built in, just select and create.

Put your stamp on every stem
Set how closely each generated part follows your playing, your harmony, and your phrasing. Dial it tighter for faithful backing, or looser for something you didn't expect. Or skip the presets and describe the exact part you want.

Fill any section, keep the groove
Highlight any part of your track and Stem Generation fills it with new ideas, transitions, or variations, without breaking what you already have. Stuck on the bridge? Select it, generate, and hear a way through.
Record a riff. Build the backing track in minutes.
For every kind of musician

Hear the whole song while it's still fresh
That chorus sitting in your voice memos deserves a full arrangement. Generate drums, bass, and keys around it and hear where the song wants to go. Write the next section instead of imagining it.

Parts that fit the session, no digging
Stop auditioning samples that almost work. Every part arrives in key and in time, shaped by everything you've laid down. Spend the night arranging, not searching.

A rhythm section behind whatever you play
Record a few bars and generate the drums and bass to play against. Practice with it, write over it, or just jam. Your part stays in front, and the backing follows you.
Make it sound like you
Full creative control, no plugin chains required.

Responds to your sound
Every generation starts by listening. Your chords, your groove, and your energy shape what comes back, so each new part lands like it was played for the song.

You stay in control
Nothing you generate is locked in. Audition another take, swap the style, or scrap it and head a different direction. The last call is always yours.

Everything in one session
Generate your parts, arrange them, and export the mix inside Moises Studio. No second app, no file juggling, no setup between the idea and the take.

Your audio stays yours
Moises never trains on your audio. What you upload powers your session and nothing else. Your recordings, your ideas, and your rights stay with you.

Charlie Puth
“I’ve been using Moises in my own creative process for years. It’s here to help artists learn, explore, and bring their ideas to life.”

Eloy Casagrande
“It's a product that I've waited for my whole life. It would have made my life a lot easier if Moises had been around for 15, 10 years.”

Cory Henry
“I find myself using Moises in creative ways, generating stems and making bass parts, while I'm trying to write a song in its infant stage.”
