Show Log

Show Log keeps a running history of what LTCast did during the show. It is passive — LTCast writes to it automatically while it runs, with no operator action. Review it after the event to confirm everything went to plan, or use it while troubleshooting to find out when something happened.

Accessing the log

The log is the lower half of the SHOW tab in the right-hand panel; the Show Timers are the upper half. The tab is hidden by default. Show it with View → Panels → SHOW, with a role preset that includes it (View menu & role presets), or with Show "Show" tab in Settings → Workflow → Appearance. The log records whether or not the tab is visible.

What gets logged

LTCast logs three kinds of event:

• transport — Play, Pause and Stop, each with the name of the song, plus New Show and PANIC.
• cue — every time a trigger fires: a MIDI note, program change, control change, MSC GO or an OSC message, with its channel and number or address and the timecode it fired at. Triggers fired by chase are marked [chase], ones sent with the test button are marked [test], and a trigger that fires well after its moment — for example because you started mid-song — carries a late by note.
• file — a song loading ("Loading: song name"), including Empty Songs.

LTC signal changes and viewer connections are not logged. For viewer activity use the Stage Monitor and the MIRROR pill.

Reading the log

Entries are listed in the order they happened, oldest first, and the list scrolls to the newest entry as events arrive. Each entry shows:

• Time of day — the clock time on this computer (your local time) when it happened, not the SMPTE timecode. Hover it to see the date and the milliseconds too.
• Event — the category (transport, cue or file)
• Description — what happened

Exporting and clearing

The CSV button saves the whole log, oldest first, as a spreadsheet file (show-log.csv, columns Time, Event, Detail). The Time column is your local date and time down to the millisecond, for example 2026-10-06 19:30:12.345. Clear All empties the log.

Log lifetime

The log lives in memory only. It holds the last 5,000 events, is not saved to disk, and is lost when LTCast quits. Starting a New Show does not clear it — it just adds a New Show line — so use Clear All at the start of a show if you want a clean log, and export the CSV before closing the app if you want to keep a record.
