Sky Auto Player Guides

First-party guides covering setup, the timing model, supported sheet formats, technical boundaries, and troubleshooting — written against the current source code.

Getting started

Installation, download and first steps

How Sky Auto Player WorksSky Auto Player reads user-provided sheet files, schedules every note against a timing model, and delivers keystrokes through the Windows SendInput API. It never reads game memory, modifies game files, or injects code.
Supported Sheet FormatsSky Auto Player reads JSON, .skysheet, and JSON-compatible TXT files imported through the Library. All three formats originate from the Sky Music editor and share the same underlying data structure.
Windows Setup and First LaunchDownload the canonical Tauri NSIS installer, install for the current user, and use the desktop Library to import sheets.

Playback & timing

How Sky Auto Player handles music and timing

The Timing EngineSky Auto Player's timing engine schedules notes against a frame-aligned timeline, submits chords in one SendInput batch, holds notes for their full duration, and measures sender-side latency to reduce systematic drift. Game-side accuracy depends on Windows and the game's own sampling loop.

Technical & safety

Technical boundaries, security and source code

Security BoundariesSky Auto Player uses only the Windows SendInput API for keystrokes. It never reads game memory, modifies game files, hooks processes, or injects code. Three security mandates are enforced in CI on every commit.
