The application I’m using needs the messages to come in the normal way. For some reason, GP is putting a space before the final address part, rather than a slash.
OSC_SendStringSpecific("/GigPerformer/Main/Voice/SongPartName/", GetSongPartName(0), OpenStageControlAddress, OpenStageControlPort)
It shows up like this on the receiving end…
/GigPerformer/Main/Voice/SongPartName Intro /GigPerformer/Main/Voice/SongPartName "Chorus End"
