Afinar
Not on a timer, on the actual recording. Your score turns its own pages in time with the song: bar for bar, repeats jumping back on time, pages turning slightly early because players read ahead.
Add the score, add the song, and the pages start turning on their own. The work happens on the way in, on your Mac, before you have even opened it. There is nothing to set up and nothing to tell it.
Play the song through once and scroll along with it. That is the whole of it. From then on the score follows on its own, like any other.
The sheet-music apps that turn pages by themselves need you to tell them when. You set a duration and hope you play at that speed, or you sit down and perform the page turns once so they can be replayed against that one recording. Neither one knows what the music is doing: not the band pushing the last chorus, not the repeat you’re on, not the drummer dragging the bridge.
The moment your playing and its counting come apart, you’re managing a page instead of playing music. Which is the one thing it was supposed to prevent.
Afinar follows the recording you’re playing along to. When the music moves, the page moves, because they’re running off the same clock.
