[PD] program changes to vst~ plugins .

[joge .]

i am playing around with the vst~ object [which is great by the way !!]  ..
but i dont seem to know how to change the program number of a vst plugin
[like pro-52] with a message in pd .  would this be a system exclusive
message and therefore not implemented yet .?
i ask because i am tring to set up a patch that will set up the pro-52
plugin on load .  is there another way of accomplishing this that does not
involve the things mentioned above ?
