Empty songs

An empty song is a placeholder in the setlist with no audio file and a length you set. It runs its own clock, so the timecode display, the countdown, markers, cues and MIDI / OSC triggers all work as they do for a real song. But an empty song sends no sound and no timecode: while one is the active song, LTC audio, MTC, Art-Net and OSC timecode are all muted. The OSC /transport and /song messages and any triggers you attached still go out.

Adding an empty song

Click the ∅ button next to + in the setlist header (tooltip: Add Empty Song). The new card, named Empty Song 1, Empty Song 2 and so on, appears at the end of the setlist. Drag it by its six-dot handle to the position you need. The button is disabled while Chase is locked to an external signal.

Setting the duration

A new empty song runs 60 seconds. Click the duration under the song's name and enter how long it should run: seconds (90), minutes and seconds (1:30), or hours (1:30:00). The length can be from 0.5 seconds up to 24 hours. 0 is not accepted — there is no unlimited length — and an invalid entry shows Invalid duration — try 1:30 or 90.

Common use cases

  • Placeholder for a non-musical moment — a speech, a set change or an intermission, so it has its own place in the setlist like any other item
  • Cue-only block — attach markers, cues and MIDI or OSC triggers to a timed block with no audio, for example to fire a lighting or video cue at a set time
  • Rehearsing cues — because an empty song sends no timecode, you can build and test a cue structure without feeding timecode to the show network

Behavior during playback

Empty songs participate in auto-advance. When the configured duration ends, LTCast follows the after-finish destination set for that song. With no destination set, it moves on to the next song only when the global Auto-advance checkbox is on; otherwise it stops. Markers, cues, and triggers can all be attached to empty songs the same as any other song.

The timecode shown on screen during an empty song starts at the song's own Start TC, which is 00:00:00:00 unless you set one in the TC Generator controls. It does not continue from the previous song.

Song card appearance

The card for an empty song has a ∅ marker before its name; cards never show a waveform. Its duration under the name is clickable so you can change it, and there is no start-timecode chip. Empty songs are not LTC-scanned, so they show no scan badge, and the missing-file check does not apply to them.

Empty songs and per-song settings

Song offset, downbeat, time signature and after-finish all work on empty songs. Trim and fades have no effect, because there is no audio.
