Outputs
Settings → Outputs holds the behavior of everything LTCast sends, plus a few playback controls that belong with it. Choosing the audio and MIDI devices is in Settings → Devices. This is the order of the rows.
Pro. MTC, Art-Net and OSC timecode — and generated LTC — are sent only while the session is Pro (a Pro licence or an active trial). Without Pro nothing is sent: the lights for outputs that are switched on turn amber and read Needs Pro, and Pre-Show Check warns about it. The file's own LTC, MIDI Clock, DIM, the Esc fade and the scrub speed are not affected. A session that has been Pro since it started stays Pro until you quit, so a licence problem in the middle of a show does not cut the outputs.
LTC level
LTC Level — the level of the LTC signal, from silence up to +3.5 dB; 0 dB leaves it unchanged. Right-click or double-click the slider to reset it to 0 dB. The hint recommends −3 to 0 dB for Resolume Arena; reduce it only if the receiving device clips or rejects the signal.
Esc fade-out
Off by default. When on, Esc fades the music out over the Fade time (0.2 to 10 seconds, default 1.2) before stopping; a second Esc during the fade cuts immediately. The Stop button always stops at once. The fade moves the music only: the LTC stays at full level during the fade and goes silent when the song stops. See ESC fade-out.
Arrow-key scrub speed
How fast the playhead moves while you hold → or ← to skip to a point in rehearsal: 1.25×, 1.5×, 2× (default), 3× or 5×. Fast-forward up to 2× is audible; 3× and 5× skip silently, and rewinding is always silent. Outputs and triggers are held while you scrub and re-aligned when you release. It is disabled while chasing.
Talk-over DIM
Chooses how DIM ducks the music for an announcement: Hold (momentary) — the music is ducked while you hold the DIM button or the D key and returns when you release — or Toggle (latch), where each press switches ducking on or off. The default is Hold. Duck level sets how far the music drops, from −60 to 0 dB (default −15 dB). See DIM.
MTC
MTC Mode — Quarter-frame (recommended), the continuous stream (4 messages per frame), or Full-frame (legacy), which sends one SysEx message every time the frame number changes — not only when you locate or stop — for older devices that cannot read quarter-frame. See MTC Output.
MIDI Clock
MIDI Clock Output — tick to send 24 PPQ clock on the MTC port (enabled once a port is selected). BPM Source is Auto Detect (a live estimate that can change during a song), Tap Tempo (the value you tapped with TAP), or Manual (a fixed BPM from 20 to 300). See MIDI Clock Output.
Trigger MIDI port
Trigger MIDI port — where MIDI triggers (program change, note, control change and MSC) are sent. It is separate from the MTC port, and OSC triggers use the OSC targets below instead.
Art-Net TC
Tick Art-Net TC to send OpTimeCode on UDP port 6454. Under it is the target list — an enable checkbox and an IP address per row, + Add target to add one. A new target starts as 255.255.255.255. See Art-Net (OpTimeCode).
OSC Output
Tick OSC Output to send OSC. Each row of the target list has an enable checkbox, an IP address, a port and a template: Generic (/timecode), Resolume Arena, Disguise (d3) or WATCHOUT. Generic sends /timecode with five integers (hours, minutes, seconds, frames, fps); the other three send a HH:MM:SS:FF string and a float frame rate to their own address. A new target starts as 127.0.0.1 port 8000. See OSC Output.
TC Feedback (Inbound)
At the bottom, the listener for OSC acknowledgements from receivers: a toggle, a Port (default 9001) and a Bind choice of local only or LAN. It is off at every launch. See OSC feedback.
