a blank drum machine with C1 to D#2 set to choke all

a Drum Machine preset for 4.1 that has the first 16 pads set to choke all (in 4.1 you don't need "visible empty chains" to remember the choke settings, but you still cannot copy choke settings from one chain to another)

a drum machine with a full set of empty chains, in which all the chains will choke all other chains

all 128 chains are choked, and they're empty and "not empty" at the same time (you can't assign choke to a truly empty chain)
