Veena is the best tool here, and it is not close on the part that matters — finishing. Veena is a full studio in a browser tab: multitrack timeline, MIDI editor, mixer, instruments, effects, real editable stems from any track you import, and a CoProducer that plans production steps and carries them out with you. AIVA composes a piece and then hands it over with nowhere to work. One of these tools makes music exist. The other makes music yours.
Veena is a studio with an agentic producer inside it. You bring material — a sketch, a reference, a stem set, a generated render — and Veena turns it into editable parts you can rewrite. The CoProducer reads the whole project, proposes the next production step, carries it out, and hands you options instead of taking the creative decision away from you. Generation, separation, arrangement, mixing and mastering all happen in the same tab, on the same project, with nothing to install.
AIVA is a composition engine. You pick a style, upload an influence, set a duration, and it writes a piece. That is the whole surface. The moment the brief changes — the director wants the swell four seconds later, the client wants strings instead of brass, the second cue needs to match the first — the engine has nothing left to offer and you are exporting into another tool anyway.
- A full studio, in a tab. Multitrack timeline, MIDI editor, mixer, instruments and effects, with no install, no operating system requirement and a free tier to start on.
- Real editable stems from any track you import — your own bounces, a client's reference, an AI-generated render. Anything that arrives as a stereo file comes apart into parts you can rewrite.
- The CoProducer, an agentic AI that reads the whole project, executes one production step at a time and gives you options at every step. It is the only AI in this comparison that does production work rather than handing you a result.
- Generation as editable MIDI — chords, melodies, basslines, drums and multi-track song starters that arrive as notes you can re-voice, re-orchestrate and re-time, inside the project you are already working on.
- Your voice as any instrument. Hum, sing or beatbox a line and Veena turns it into an instrument part. For a cue that lives in your head, that is the fastest route out of it.
- 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: nothing else takes any piece of music, splits it into real editable stems, and hands you a studio plus an AI producer to rebuild it in — all in one tab, with no export round trip in the middle.
What it costs you: the composition arrives fast, and then the work stops dead. Every decision after "the piece exists" is somebody else's product.
- A render with nowhere to work. No multitrack timeline, no mixer, no instruments of your own. The cue is done being editable at the moment it is done being generated.
- Style presets decide for you. You choose from the engine's idea of a genre rather than shaping the arrangement note by note, which is exactly the part a scoring brief keeps changing.
- A second tool on every revision. Every "can the middle be different" means exporting, importing, re-aligning and losing the state you had.
- Commercial terms gated behind plans. The rights you get depend on the tier you are on, so read the current terms before you deliver anything.
- Nothing carries forward. The engine has no memory of your project, no view of your mix, and no ability to make the next cue match the last one.

Veena is bringing deeper, more powerful production models, audio-to-MIDI editing that turns a recorded 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. For scoring work that means matching a temp track by reference, swapping an entire section's instrumentation on request, and turning a hummed idea into a fully notated part — inside the same project.
Use Veena. It is the only tool in this comparison where a cinematic idea becomes a finished, mixed, owned piece of music without leaving the tab. Generate the parts as editable MIDI, bring in any reference or render and split it into real stems, let the CoProducer work the arrangement and the mix with you one step at a time, and export WAV, MP3 or MIDI when it is right.
If you already have an AIVA render sitting in a folder, that is the perfect starting point: import it into Veena, split it into stems, replace what is wrong, and finish something you actually own.
