Not to pour any cold water on this feature, I love the feature and use it a lot, but if you string more than 4-5 of these together and close the patch and reopen, it is basically a coin toss if it will recognize all the expanders on the open and you may have to drag and reconnect them somewhere in the chain to get them all flowing together again. Easy way to tell is hover over the Steps knob and see how many steps are actually connected. PGMR has the sickness as well, too may chained and you have to check patch on reopen.
I think this was fixed. But, I never did any testing to confirm. I’m not a fan of ADDR-SEQ. It is probably great module, but I always have to fight it to get it to do what I want and to confirm that it is still doing the same the next time I open it. My opinion may be outdated though.
