[PD] vline~ helpfile

[hans w. koch]

hello,

maybe i am doing something stupid, but i don´t get the vline~ synthax:
the helpfile states: "Any number of future ramps may be scheduled and vline~ will remember them and execute them in order. 
They must be specified in increasing order of initial delay however, since a segment cancels all planned segments at any future time.“

then there is an example with a message box containing: 1 1000, 0 0 1000, 1 1000 1000
but it doesn´t do more than ramp from 0-1 in a little more than a second.
isn´t it supposed to ramp up then down to 0 in another second and then up again?

(using pd47-1-64 bits on osx 11.6. btw)

thanks for any pointers
