I’ve been having similar problems with arranger mutes when using THRU machines. Two work-arounds I’ve used is to make a scene that mutes the track and put that in the arranger instead. Or to make a copy of the pattern with a P-LOCK VOL 0 on the first step of the THRU machine I want to mute.

Still would be interesting to know what going on here, because sometimes the mutes work, sometimes they don’t and I can’t figure out why. I only get this on Thru and Neighbour machines. So that must be part of the puzzle.
