looks like i misunderstood CZ clipping. using a second CZ as depicted in any of these SSs does clip the last stack of CZ. bollocks. i thought the simulation was mishandling the second CZ since after a bunch of changes in the sequence editor it starts throwing out lots of erroneous numbers and you have to rebuild it from scratch.

well back to the CZ drawing-board. i just hate the thought of refreshing CZ during steady hands. i want something better than that..
