XAPBob, funny you should bring this up since I was revisiting this again last night and had forgotten about my post here!
Sadly the answer is no which is a real shame. Part of me thinks it ought to be possible with either MIDI or OSC calls. I current use of SCS to play lyric videos and to send OSC commands to atemOSC for our livestream. However, I am trying to prepare for being back in church with live services again.
Another thought would be to somehow run commands from OpenLP (eg javascript) to send the OSC messages. However, I can't work out how to do that either!
Any input gratefully received since sadly it looks as if we will be going either to ProPresenter or Proclaim.
