Hey @nevillewhitemusic,
Quick follow up on this one: AbleSet 3.2.0 beta adds a device setting for the lyrics track shown in Performance View, so you can now switch it via OSC without needing a Canvas:
/devices/setSetting all performance.lyricsSlug lyrics-chords
/devices/setSetting all performance.lyricsSlug lyrics-only
The last argument is the slug of the lyrics track. You can double check it by opening that track in Lyrics View and looking at the end of the URL, e.g. /lyrics/lyrics-chords.
Replace all with a device name if you only want to switch it on one device. Like before, you can send these from a MIDI mapping (Custom OSC), a Canvas button, or an OSC track if you want it to switch automatically at certain points of a song.
You can download it here: AbleSet 3.2.0-beta.12
Hope that helps!
