VCA gate time is set to 'long' not 'medium', so switching between env and gate has no effect if your adsr setting mimc medium which mine did. you have to reset it in the software.
i thought mine was broken since the sequencer would not trigger (because it was set to gate not clk) and the VCA gate/env switch didn't do anything.
after resetting them in the software everything is hunky dory.
Really, in a firmware update, defaults for existing parameters should not change. If they do it should be in the readme.
