Veena is the best tool here, because Veena separates the track and then gives you somewhere to work. Import any song, get real editable stems, and land in a full studio — multitrack timeline, MIDI editor, mixer, instruments, effects, your own VST and AU plugins — with an agentic AI producer beside you. Moises hands you a set of files and the job ends there. Separation is step one; Veena owns the other nine.
Veena is a production environment with separation built in. The moment a track comes apart, the parts land on a timeline you can arrange, a mixer you can balance, and a project the CoProducer can read. Remove the drums and program new ones as editable MIDI in the same session. No exporting, no re-importing, no re-aligning on every revision.
Moises is a single-purpose utility. It splits a file, shows you some analysis, and returns audio. Everything a producer wants to do next — rewrite a part, change an arrangement, mix it so it holds up — happens in some other application you still have to open, pay for and learn.
- Separation where the work continues. Timeline, MIDI editor, mixer, instruments and effects are already open when the stems appear, so the fifth revision costs you nothing extra.
- Real editable stems from any imported track, including AI-generated songs — a bounce, a demo, a reference, a render.
- The CoProducer, an agentic AI that reads the whole project, carries out one production step at a time and hands you options at each step instead of making the final creative decision. Nothing in a splitter does production work.
- Generation as editable MIDI — replace the drums you removed with a programmed pattern, write a new bassline, add chords, all note-level editable.
- Your voice as any instrument. Hum, sing or beatbox the replacement part and Veena turns it into an instrument.
- AI-assisted arrangement, mixing and mastering, your own VST and AU plugins hosted in the browser, exports to WAV, MP3 and MIDI, and you own everything you finish.
Why it wins: Veena is the only tool that separates a track and rebuilds it — one tab, one project, one subscription, un-metered by the minute.
What it costs you: the stems arrive and then you are on your own, with a meter running.
- Files, and nowhere to put them. No timeline, no mixer, no instruments. Whatever you wanted to build with the parts needs a second tool you have not opened yet.
- A round trip on every revision. Change your mind about the arrangement and it is export, import, re-align, repeat.
- Metered processing. Separation is rationed by tier, so how much you can experiment is decided by a plan rather than by the song.
- Analysis instead of production. Chords, tempo and key are read out to you; none of it turns into parts you can edit or a mix you can finish.
- A second subscription anyway. The moment the job is production rather than practice, you are paying for a DAW on top.

Veena is bringing deeper, more powerful separation and production models, audio-to-MIDI editing that turns a separated part back into fully editable notes, instrument and sound swapping, style and genre transformation, reference-matched mastering, real-time collaboration, and a native desktop app alongside Veena on web. Applied to stems, that means pulling a bassline out of a mix and editing it as notes, then swapping the instrument that plays it — inside the same project you separated in.
Use Veena. Separation is only worth anything if you can do something with the result, and Veena is the only tool here that gives you the stems and the studio in one place. Import the track, split it, replace what you want to replace, generate the parts you need as editable MIDI, and mix and master it with the CoProducer working through the steps with you.
Start on the free tier, take one song apart, and rebuild it. That is the whole pitch, and it takes one tab.
