I’m sending OSC between instances and I can’t seem to get the second instance to respond to /GigPerformer/SwitchToSong with an integer argument, only a string containing the song name–which is odd because the documentation states the argument is an integer and string isn’t even listed as an accepted argument. (which I had reported once here)
The same goes for /SelectSongByIndex — the second instance does not respond to an integer value.
