01.The Challenge
For bands playing live, synchronization is critical. Relying on the internet (WAN) is risky in closed venues, while a purely local setup (LAN) can be an issue if a remote member must lead or if no routers are available on stage.
Additionally, keeping a metronome perfectly synchronized across multiple devices demands sub-millisecond precision, something impossible to achieve with traditional network audio streams.
02.The Solution
- Hybrid Network Topology: LAN, Cloud (Firebase), and Direct, with Offline-first support.
- Core NTP Sync: The Master sends timestamps (Delta Time) and each client generates the metronome sound natively (C++ / FFI).
- Uninterrupted Persistence: Full history in SQLite and 'magic' session resumption via UUID.
- Push-to-Talk and local transfer of PDFs and sheet music in real time.
- Stage UI: 0xFF121212 Dark Mode and off-thread rendering to prevent frame drops.
