ähmm, are you sure you have looked at 2.control.examples/16.more.arrays.pd ?

as far as i can tell the "bounds" message is exactly what you are
looking for.
the only weird thing is the order of arguments:
[bounds <Xmin> <Ymax> <Xmax> <Ymin>(
(i guess this is due to the constant turning the graph upside down: if
your origin is the upper-left corner of the screen, you will have
[bounds <Xmin> <Ymin> <Xmax> <Ymax>(, but unfortunately we are so used
to having the Y-axis pointing upwards)

so:

[bounds 0 128 100 0(

[s array]

should rescale your 100-points array for MIDI-values (visually!, the
values stay the same)

btw: you can also change the scaling factor via the properties menu of
the array (right click on a graph and select properties)
