DiGiCo LiveTrax integration

[benfeinberg]

The latest DiGiCo update (v22) adds an integration for Harrison LiveTrax 3 that sends the current snapshot over OSC. Using the LiveTrax integration allows us to use MarkerMatic without taking up the iPad slot on the console.

When the integration is enabled, the console appears to send OSC messages of the form /snapshot [s] "1.00 Cue Name" to UDP port 3819 at the configured LiveTrax IP address. We can configure an OSC server in MarkerMatic to listen for these messages and forward them to Reaper.

The console integration also adds a couple of built-in macros that send OSC, only some of which obviously map to MarkerMatic macros. For now I just mapped the ones that seemed useful, but the rest would be easy to add too.

• Play (/transport_play)
• Stop (/transport_stop)
• Rewind
• Forward
• Return to Start
• Record Arm (/rec_enable_toggle)
• Add Marker
• Locate Marker (specify the name of a marker to go to)
• Send Cue Markers (enable or disable the console sending snapshot messages)

It also appears to be possible to add a MacroOSC instance pointing at the same IP address and port to send custom messages to the same place.

Currently MarkerMatic will show the console as connected as soon as it receives any OSC, and will never notice if it disconnects. I didn't see any useful status messages from the console, but it's possible I missed something.

This was tested and worked on a Q225T running V2232.

Hi Ben- Thanks for this, and this is conceptually implementation we've been thinking about too. I'd love to take you input- and note that you've marked this as Draft for now- let me know when you're ready for us to take a look at what you've got, and we'll be happy to!

Sorry for stalling on this. I was hoping to go back and figure out how the LiveTrax integration syncs channel names from the console, but life got in the way unfortunately.
