Timecode Config

Configures which source provides the timecode signal to the whole system. At the top of the page, the currently active source is shown with its live timecode value and framerate. The TC display updates every second.

Select one source and click Save & Restart Listener. Restarting the listener briefly interrupts the TC signal.

Art-Net

Listens for Art-Net timecode broadcast on the local network. No per-field configuration is needed — the page shows the UDP port the listener is watching. Ensure your firewall allows incoming UDP broadcast traffic on that port.

A reliable method when your lighting desk or TC distribution rack outputs Art-Net.

MIDI Timecode (MTC)

Reads timecode from a MIDI interface. Useful when your TC distribution runs over MIDI.

• Prefer Input Number — select the 1st, 2nd, etc. detected MIDI input on the server. Use this when the MIDI interface name is not consistent across restarts.
• Interface Name — alternatively, specify the interface by name (disabled when Prefer Input Number is set above 0).

LTC (Audio)

Reads timecode from an audio input device connected to the server machine. A dedicated audio interface is recommended for reliable decoding.

• Audio Device — select from detected audio inputs on the server machine
• Channel — which audio channel carries the LTC signal (1–8)
• Sample Rate — the audio sample rate: 44100 Hz, 48000 Hz, or 96000 Hz. Match this to your audio interface settings.
• Gain — a pre-amplification factor applied before decoding (range 0.1–10, default 1.0 = no boost). Increase if the LTC signal is too quiet to decode reliably.

MANet (GrandMA)

Receives timecode from a grandMA2 or grandMA3 lighting console over the local network using the MA proprietary protocol.

• GrandMA Version — select GrandMA 2 or GrandMA 3
• Session ID — the MA session the listener should join (1–32 for GMA2, index 0–31 for GMA3)
• Timecode Slot — which of the 8 timecode slots on the console to read from (Slot #1–8)

Caution

This is an unofficial, undocumented integration not affiliated with MA Lighting. It is suitable for reducing carry-on equipment during testing or rehearsal, but is not recommended for production use. The protocol may change without notice in any grandMA software update. For mission-critical shows, use MIDI or Art-Net timecode instead.

Realtime Clock

Uses the server’s own system clock as the timecode source. No external hardware needed.

• Framerate — choose 1, 10, 24, 25, or 30 fps

Useful for development, testing, or when no external TC source is available.
