Download

Pre-built binaries for macOS and Windows: GitHub Releases. No Python install required — just download, unzip (macOS) or run (Windows).

Features

• LTC Timecode Decoding — reads SMPTE/LTC timecode from any audio input via libltc
• Non-Linear Cue Triggering — cues trigger by timecode hit in user-defined order, not sorted
• Cue List — timed cues with names, descriptions, colours, section dividers with cue counts
• Per-Operator Comments — configurable operator list with role-semantic colours (Lighting blue, Audio amber, Stage Manager purple, customisable per role) so each operator picks out their column at a glance
• Performance Mode — full-screen operator view with large fonts, countdown timer, role-coloured operator columns, and a one-tap full-cue-list overlay
• Web Remote — serve Performance View to any device on the local network via WebSocket; password-protected access; operator-specific filtering so each phone shows only the cues its operator owns
• Duplicate Timecode Detection — amber row tint, left stripe, and "DUP" pill in the cue list; identical detection in the cue table and any future cue-list export
• Signal Monitoring — five-bar VU meter, semantic LIVE / WEAK / CLIPPING / NO SIGNAL states, signal-loss blink
• Show File Format (.ojeshow) — single JSON file with all settings + cue list, autosave on dirty, crash-recovery prompt on next launch
• Unified Dark Design System — single token vocabulary across the desktop UI, the cue table, Performance Mode, and the web remote so colours mean the same thing everywhere they appear (green = active / locked, amber = warning / duplicate, red = stop / no signal)
