yes it works but only if you cue a pattern. it doesn’t work at all if you chain 2 patterns together, or in song mode.
so, if you make a song, and one of the patterns has master set to INF and CHNG set to 64, the song will simply get stuck on that pattern and repeat indefinitely, and never move on.
the manual explicitly states that the CHNG parameter is meant to work with cueing AND chaining:
this is currently not functioning as described. latest version of the manual, updated March 8, 2018 i believe.
