Leader playback control
The leader controls tempo, repeats, and the starting measure, so the whole ensemble moves as one. In personal-practice mode, each player loops just the passage they need.

Where rehearsals become works.
Each part, prepared apart, comes together on the same measure.
The friction of rehearsing together
You spend more time
getting in sync than playing.
Finding scores, aligning parts, checking who's ready. The time to actually play together keeps getting pushed back by prep.
Scattered scores
The latest scores, parts, and edits are strewn across chat and email, so you hunt them down before every rehearsal.
Rehearsals that keep breaking
Page turns, finding repeats, checking notes — every leak of time is time you can't spend playing together.
Prep you can't see
It's hard to tell how far each part has prepared, so rehearsal time goes to status checks.
So Opusis gathers all of that prep into one rehearsal room.
Prepare ahead
All your pre-rehearsal prep,
done in one room.
From uploading scores to planning rehearsals and scheduling — everything that used to be scattered lives in one rehearsal room. On the day, there's nothing to line up; you just start playing.
