An Update on Sheet Music Annotation in METRO X

Annotation and markup in the METRO X sheet music reader is temporarily paused while we rebuild it properly. The PDF reader, library, and patent-pending floating Orb are unaffected — and annotation will return in a future update.

We've temporarily turned off sheet-music annotation and markup in the METRO X NOTE reader. It wasn't built the way we wanted it to be, so rather than ship something half-right, we've pulled it back to rebuild it properly. Here's exactly what that means for you.

What changed

The annotation tools — highlighting, marking up, and writing on your scores — are paused for now. Nothing else about the NOTE sheet music reader has changed. We made this call because the first version of annotation didn't meet the standard we hold the rest of the app to, and we'd rather take it offline than leave a rough feature sitting in your practice flow.

What still works

  • Import any PDF. Files, iCloud, email, AirDrop, web download — all unchanged.
  • Your library. Organize, tag, and pin your scores exactly as before.
  • The floating Orb. The patent-pending visual beat still sits right on top of your score while you play.
  • Loop a passage. Mark a section and ramp the tempo up over each pass.

When it's coming back

Annotation is firmly on the roadmap. We're rebuilding it from the ground up so it feels as natural as writing on paper, and it will return in a future update. We didn't want to remove it quietly, so we're telling you up front — and we'll announce it here the moment it's back.

In the meantime, the heart of NOTE is still here: read your score and follow the floating Orb, all on one screen. Read how the floating Orb works, or how to practice with a metronome.
