Question 1

Why not use ACE Studio, Cantai, or OpenUtau?

Accepted Answer

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.

Question 2

What file format works best?

Accepted Answer

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.

Question 3

Can I upload a PDF score instead of MusicXML?

Accepted Answer

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.

Question 4

Can I use this for choir rehearsal tracks?

Accepted Answer

Yes. That is one of the strongest near-term use cases: turning a prepared score into part-learning references and quick rehearsal demos.

Question 5

Are the current AI voices royalty-free for release?

Accepted Answer

Not yet. The current voices are appropriate for evaluation, rehearsal, and demo use. Royalty-cleared options will be introduced as paid plans mature.
