Common questions about MusicXML support, choir rehearsal tracks, PDF conversion, voice licensing, and how the workflow fits beside traditional production tools.
FAQ
Those tools are built for detailed vocal production and note-by-note control. SightSinger is built for score-led vocal demos and choir rehearsal tracks using natural-language directions instead of deep DAW or phoneme editing.
MusicXML (.xml or compressed .mxl) from MuseScore, Finale, Sibelius, Dorico, or Logic Pro is the best fit because it preserves the score structure and lyric data the workflow depends on.
Yes. The MusicXML solfege tool supports movable-do major, minor-la, and minor-do settings, so you can choose the convention that matches your choir, classroom, or sight-singing method.
Movable-do names notes by their scale degree in the current key, so do moves with the tonic. Fixed-do names written pitches directly, so C is do, D is re, and chromatic pitches use altered syllables.
The free browser tool labels the top note by default when a selected part contains chords or multiple voices. Use SightSinger Studio when you need to split harmony parts and hear the result sung.
SightSinger works best once the score is in MusicXML. If you start with a PDF, use an OMR workflow first, then clean the MusicXML before generation. The Learn hub includes a guide on moving from PDF-based notation into a better MusicXML-to-singing workflow.
Yes. That is one of the strongest near-term use cases: turning a prepared score into part-learning references and quick rehearsal demos.
Yes, when you use an AI voice that is marked as available for commercial use. Commercial-use voices can be used in releases, videos, rehearsal products, client demos, or other commercial projects, subject to each voicebank's credit notes and usage rules.
For those commercial-use voices, SightSinger does not charge extra royalties on the generated vocals beyond your plan or subscription. You are still responsible for having the rights to your uploaded score, lyrics, arrangement, and final use.
Check the Credits and AI Voice Permissions page before publishing to confirm whether the selected voice is cleared for commercial use and whether it requires AI disclosure, voicebank credit, illustrator credit, or character-use restrictions.
Your account will be topped up immediately to the monthly credit amount of your selected paid subscription plan.
No. Your remaining trial credits will stay active until your trial expiry date. After the trial expires, your account will move to the permanent free plan, and free credits will reset monthly from then on.
No. All features are available on the free plan too.
As a solo developer, I understand how frustrating it feels when features are locked behind a paywall. Thus paid subscriptions mainly give you more credits so you can generate longer songs, more parts, and use SightSinger more regularly.
