Sky Auto Player for Sky: Children of the Light · Windows 10/11
Play the sheet. Not the keyboard.
Load a Sky music sheet, switch to the game, and let every note, chord, and hold land on the beat — scheduled from the sheet's timing model and dispatched through Windows SendInput.

- Holds keep their full duration, never clipped
- Player and display on separate threads — HUD stays smooth
Built around the music
Timing is the instrument.
A sheet is more than a list of keys. Chords must arrive together, fast passages need consistent spacing, and holds need their full duration. Sky Auto Player schedules those musical events as a performance rather than replaying a generic macro. Dispatch timing is measured at sender-side completion — not just the scheduled timestamp.

Technical boundaries
Clear about what it does—and what it does not do.
