Preparing the choir.
The renderer is ready.
Vocal parts follow the score’s clefs, with separate staves for independent lines. The paper travels steadily; rubric notes and words are sounding now. A small ← at the left edge marks a held note that has travelled out of view.

New sound and quality choices stop playback; press Play to restart. Desktop buffering favors steady playback, so controls may take a moment to reach the speakers. Room amount and decay apply to the three new rooms. Shared intention enables staggered breaths when a section has more than one singer.
Choose an example or keep this choir, then prepare a matched pair.
Listen for a settled solo vowel, a shared arrival and release, clear harmony through the tail, and any useful difference in high quality. A/B uses the same score, seed, tempo and mix, with one measured gain per complete phrase.

All controls glide into a performance already in progress. Air is shaped aspiration; Consonants governs only brief colored gestures.
The seed and numbered step make every result reproducible.
In, solo, and level are the conducting row. Each written range is checked against that singer’s persistent comfortable range.
| Singer | Part / range | In | Solo | Level |

Register and range describe color and comfort; they never transpose the score. Every change below is live.
Counts draw from a persistent six-singer pool per ordinary section and ramp live. Part mute and solo are live; an individual solo temporarily takes precedence.
| Part | Lanes | Singers | Mute | Solo |

Positive values delay the score to meet sound buffered after the browser, such as Bluetooth. Negative values show it earlier. This changes only the display, never playback or WAV files; acoustic delay cannot be measured without a microphone loopback.
Timing capture stays on this device. No microphone, score content or automatic upload.
The compact versioned JSON keeps this exact choir but not the score. Score, tempo, and ensemble seed are structural and stop playback before rebuilding.
Each visit begins with Choir 1. Restore saved setup recalls this browser’s last setup for the current score; Load settings restores an exported file exactly. Deliberate changes update the browser’s saved setup.
