Use a vocal synthesis tool to create a separate guide track for each choir part, then combine those parts with an accompaniment track in an audio editor. For a Xiaomi, Redmi or POCO phone, the practical role is to review and rehearse the exported audio; the listed tools do not establish a complete choir-track workflow that runs entirely on Android. Choir-specific presets, part-count limits and rehearsal features are not established, so check each vendor’s site before choosing a tool.
Choose A Workflow That Fits Your Choir Track
| Tool | What The listed features support | Important limit |
|---|---|---|
| Synthesizer V Studio 2 Pro | MIDI-based synthesized vocals with detailed pitch, timing, pronunciation, timbre and expression editing; standalone and plug-in versions. | Windows and macOS desktop only; no voice cloning. Choir-part workflow is not specifically stated. |
| ACE Studio | Generates singing vocals from MIDI and lyrics and can render separate tracks. | Windows and macOS desktop only. Voice- and feature-specific licensing exceptions apply. |
| LyricToMelody AI | Generates melodies and sung vocal drafts from lyrics or MIDI, with MIDI, audio and separate-stem exports. | Web application; Starter projects are retained for 7 days. Commercial rights are included on paid plans. |
| Audimee | Harmony maker supports up to five harmony tracks; also offers voice conversion, pitch editing and stem splitting. | Web only. Its listing does not establish choir-part notation or a full choir rehearsal workflow. |
| LALAL.AI | Can separate vocals and instruments from audio, which may help prepare a practice reference from a recording. | Free Starter previews do not include full result downloads. Separation does not create or verify choir parts. |
Prepare The Music And Decide What Singers Need
Before generating audio, settle the song version, key, tempo and part assignments. Choir singers need a clear pitch reference and enough space to hear their own line. A full mix can hide an inner part, so plan one file with all voices and accompaniment, plus focused files where a single part is louder or the other parts are quieter.
General shopping ads
- Use a legally obtained score or MIDI, or enter the notes and lyrics you have permission to use. None of these listings establishes automatic choir-score transcription.
- Write down the exact notes and lyrics for soprano, alto, tenor and bass where those parts apply. Confirm ranges with the choir director; no listed tool establishes that it will arrange or transpose a choir safely for you.
- Choose whether the singers need sung guide vocals, a piano or instrument reference, or both. These tool listings do not establish a dedicated piano-accompaniment feature.
- Set a consistent tempo and count-in plan. A count-in feature is not established for these tools, so add one during assembly if needed.
Build The Parts In A Singing-Vocal Tool
With Synthesizer V Studio 2 Pro
- Prepare a MIDI line for one vocal part at a time. Synthesizer V supports MIDI and detailed editing, but its listing does not establish choir arrangement from a score.
- Enter the lyrics and adjust note timing, pitch, pronunciation, timbre and expression until the line is a useful pitch guide. Listen for syllables that fall awkwardly across notes.
- Render each part separately if your project setup permits, naming files clearly, such as “Alto Guide” and “Tenor Guide.” The listing supports a standalone app and plug-ins but does not state export formats, so check the vendor’s current details.
With ACE Studio
- Provide a MIDI line or lyrics for a vocal part; the listed features support singing generation from both.
- Generate the part and use separate-track rendering to keep it distinct from other lines.
- Repeat for each part and check the plan’s voice and feature licensing terms before using cloned or other voices. Exact choir-specific capabilities are not established.
With LyricToMelody AI
- Enter lyrics or MIDI to make a sung vocal draft or melody for one part.
- Export audio, MIDI or separate stems for assembly. The available listing does not establish a dedicated SATB arrangement mode, so create and check each line yourself.
- If using Starter, save your work locally within the stated 7-day project-retention period. Commercial rights are stated for paid plans; check the vendor’s terms for your intended use.
Make A Harmony Layer Or Prepare A Reference Recording
Use Audimee For Harmony Tracks
Audimee’s Harmony Maker supports up to five harmony tracks. Use it where a harmony layer is useful, then listen to each result against the intended score. The listing does not establish that it can follow assigned soprano, alto, tenor and bass notation, so do not treat generated harmonies as verified choir parts.
Use LALAL.AI To Separate Existing Audio
If you have a recording you are allowed to use, LALAL.AI separates vocals and instruments. This can help you make a reference version with the vocal or instrumental component isolated, but separation is not the same as extracting individual choir sections. Its free Starter plan offers previews and does not include full result downloads; check current vendor terms and plans if you need saved files.

Assemble And Check The Rehearsal Files
- Put the accompaniment and each generated part into an audio editor or multitrack tool you already use. The listed products do not establish a particular Android editor or a shared export format across all tools.
- Align the files at the same starting point and match their tempo. If parts drift, return to the MIDI or source arrangement and correct timing before exporting the set.
- Make a full choir mix, then a practice mix for each section. Keep the target section prominent and lower other guide parts enough that singers can follow their own line.
- Listen through each file on your phone speaker and headphones. Check the opening, entrances, cutoffs, lyric pronunciation, volume balance and whether the accompaniment masks the guide voice.
- Export clearly named files and play them in the same way singers will access them at rehearsal. The exact audio formats and export controls vary by tool and are not established for every product here.
Handle Voice Consent And Usage Terms
Get consent before recording or uploading a singer’s voice for custom voice training or cloning. Check the relevant platform’s terms for voice use, covers, source recordings, samples and commercial use. The stated commercial-use detail here is limited to LyricToMelody AI paid plans; ACE Studio notes voice- and feature-specific licensing exceptions. The other listed features do not establish blanket permission for a song or voice.
