Summary0008543: Allow OSC /add_marker to specify the marker's name
DescriptionThe OSC /add_marker message adds an unnamed marker at the moment. I'd like to be able to specify the marker's name.

My patch for this is attached - it just adds a third version of /add_marker which takes a string parameter. It would also be possible to add a fourth version that takes both a position and a name, but I don't have a use for that myself - I can update the patch if you'd like the symmetry, though.

I've been using this since last year as part of a presentation recording setup. I've configured a slide viewer to send OSC messages on page changes, so I get a "page 42" marker at each slide transition, then I have a script ( which reads the Ardour project and slides PDF, and renders out a video file.
TagsNo tags attached.
