What does it mean when the playing_slot_index property of a track is -2?
I’m using [live.object] to get the playing_slot_index property of the tracks in a Live session. The docs say that this property will have a value of -1 when no clip is playing in a given track; and the index of the clip slot being played (with offset 0) otherwise. I’m finding that it occasionally returns -2 when no clip is playing. What does this mean?
