Also thought if there can be sheet music or music linked to the midi file playing
ie maybe can use automation to show lines/sheet music
but would be out of this world to follow a sheet music/lyric as it plays
In the new app version 2022-12-12 released today, you can use a standard MIDI file instead of an automation track to trigger any app action listed on the Settings > Remote Control page. This includes scrolling to pages or markers, but not lyrics highlighting because that requires a line number value that remote control doesn't support.
To use this new capability, you need to set Settings > Audio & MIDI > Send SMF Data To Port to Set List Maker. This means you cannot send MIDI data from an SMF to other devices while also sending it back into Set List Maker. If the port is set to anything other than Set List Maker, the app will not respond to its own SMF files.
