Dave Smith Instruments SYNTHESIZERS

messing around with my desktop evolver today pressing multiple buttons
i found, beyond knowing:
[1][2] shows the pic version
[1][3] shows the dsp version

i found that:
[2][6] puts it in sequence edit mode
[3][6] is start/stop

and the ones that i haven't much of a clue what they do:
[main][1] does a count down from 4 to 1
[main][5] countdown from 4 to 1
(though it made all of the patches pretty much pure noise, noise level
was at zero. turning the evolver off then back on got it back to normal)
[1][5] countdown from 4 to 1
[4][7] countdown from 32 to 1
[4][8] countdown from 59 to 1

what are these doing? i suppose they are resets or calibrations of
some sort. does anybody know? and sorry if this has already been
covered here.
