Outputs
Settings β Outputs configures the behavior of all protocol outputs. Each protocol has its own section within this settings page.
LTC section
LTC Level β the output level of the LTC signal in dBFS. Right-click the knob or slider to reset to 0 dB. A level of -3 to 0 dBFS is recommended for most mixing consoles and Resolume. Reduce this only if the receiving device clips or rejects the signal.
ESC Fade-out β enable to fade the music track smoothly when you press Stop (Esc), instead of cutting abruptly. Set the fade duration in seconds. The LTC signal is not faded β it stops immediately on Stop regardless of this setting.
DIM (Talk-over DIM) β enable to duck the music output level temporarily for an announcement. Choose Hold mode (active while the key is held down) or Toggle mode (press once to activate, press again to restore). Set the duck level in dB β how many decibels the music drops when DIM is active.
MTC section
MTC Mode β choose how MTC is transmitted:
- Quarter-frame β continuous MIDI quarter-frame messages during playback; the standard mode for real-time sync
- Full-frame β sends a full-frame SysEx message on locate and stop; used for legacy devices that only need position updates
MIDI Clock section
MIDI Clock Output β toggle to enable MIDI Beat Clock output on the selected MTC MIDI port.
BPM Source β how LTCast determines the tempo for MIDI Clock:
- Auto Detect β derives tempo from the audio file
- Tap Tempo β uses the BPM tapped in the Transport area
- Manual β enter a fixed BPM value in the field that appears
Art-Net TC section
Toggle Art-Net TC on to enable Art-Net timecode output (OpTimeCode packet). Add target IPs in the list β each row has an enable/disable toggle and an IP address field. Multiple targets are supported simultaneously.
OSC Output section
Toggle OSC Output on to enable OSC timecode messages. Enter the Target IP and Port of the OSC receiver. Use the Format template selector to choose a preset message format: Generic, Resolume, disguise, or Watchout. The Generic template sends /timecode HH MM SS FF; the other templates use the address and argument format expected by that software.
