AI Summary

Enhances OSC reliability by adding beat counting addresses and fixes a bug where band pan sources were not functioning. The update ensures external lighting rigs capture a higher percentage of audio events.

Key Highlights

  • Added new OSC addresses (`/phosphor/audio/beat_count`, `/downbeat_count`) for reliable beat detection.
  • Fixed band pan sources (Sub Bass through Brilliance) that were always reading zero.
  • New beat counters restart at zero when switching audio devices.
  • External lighting rigs will now catch 100% of beats instead of only 31%.

New Features

  • New OSC beat count addresses

Full Release Notes


### Added
- **Beats sent over OSC no longer go missing.** `/phosphor/audio/beat`, `/downbeat` and `/drop` last a single render frame while OSC transmits at 30 Hz, so external lighting rigs caught only 31% of beats and 16% of downbeats in a 60-second test. New `/phosphor/audio/beat_count`, `/downbeat_count` and `/drop_count` addresses carry a running total instead — bind those and you catch every event. They restart at zero when you switch audio device, so trigger on the value changing rather than increasing.

### Fixed
- **The seven per-band pan sources never moved.** `Band Pan Sub Bass` through `Band Pan Brilliance` appeared in the binding matrix but always read zero, so anything bound to one did nothing.

## Downloads

| Platform | File | Notes |
|----------|------|-------|
