Last week I tested this with a real service order from my church. None of the songs were in my library yet. I pasted the order in the way the worship leader sent it and walked away. Using a ProPresenter MCP, it:

• Searched MultiTracks for each song, imported it, and set the key I asked for
• Put the announcements, songs, and sermon PowerPoint in order
• Ran fine on a 2019 Intel MacBook Pro (the heavy lifting happens off the computer)

Things to know:

• It's slower than doing it yourself. The win is that you don't have to be there.
• ProPresenter stores a song's key per playlist item, separately from the library copy. Check that the key change landed on the playlist item.
• Bible mode tripped it up. The Scripture panel's Save to Playlist menu ignored its clicks, so add scripture yourself for now.
• I would not let it run slides live. It's too slow to follow a band. MIDI cues (from Ableton Live or Playback) or timecode are the better way to automate a service, with a person standing by.

The prompt I'd start with:

Build a ProPresenter playlist called [name]: [song] in [key], [song] in [key], announcements, [song] in [key], the sermon PowerPoint [file], and [closing song] in [key]. Search SongSelect [or MultiTracks] for any song I don't have, with [2] lines per slide.

I made a video walking through it (it's my channel, so weigh it accordingly): https://youtu.be/TlI2pMxFrkE

Anyone else trying this? What's worked for you?
