Timecode

All timecode settings live in Preferences → Timecode.

ShowRevue reads timecode from four sources in this priority order:

  1. LTC (audio). Highest priority. Recorded with the video and decoded during playback.
  2. sACN E1.31. Multicast UDP timecode. Requires Solo or above.
  3. ArtNet Timecode. UDP port 6454, opcode 0x9700. Requires Solo or above.
  4. MTC (MIDI Timecode). Built from MIDI quarter-frame messages.

LTC setup​

  1. Connect the LTC source to an audio interface input.
  2. Open Preferences → Timecode.
  3. Under LTC Source, choose the audio device.
  4. Select the correct channel.
  5. Wait for the toolbar LTC chip to turn green.

ArtNet Timecode setup​

ArtNet Timecode is a UDP-based protocol broadcast on port 6454. GrandMA3 version 2.4 and later can output ArtNet Timecode natively.

  1. Open Preferences → Timecode.
  2. Enable ArtNet Timecode.
  3. The status shows Listening… when waiting, and Receiving (green) with the sender IP once packets arrive.

GrandMA3 (v2.4+)​

On the MA3 console:

  • Go to Setup → Network → Timecode.
  • Set Output Protocol to Art-Net Timecode.
  • Ensure the console and Mac are on the same subnet (Art-Net uses broadcast).
  • Start a timecode session — ShowRevue picks it up automatically.

Make sure the Mac's firewall allows incoming UDP on port 6454.
