[PD] wrapper for vst~ with load & save

[Peter Worth]

i've been trying to write an abstraction which is a kind of wrapper
for the vst~ object. i've attached what i've done so far.

the only creation argument of the object is the dll name of the plugin
you want to use. the idea is that you can then open the abstraction,
edit the parameters of the plugin, then click on save, which writes
all the parameters to a array, so that when you click on load the
values are read from the array and set in the plugin. when the object
is created it automatically loads the current array (which will have
been saved from last time the patch was open). this means you dont
have to set all your plugin values every time you open a patch.

does anyone have a more elegant solution to this? it works fine excet
for one problem: when i use the SIR convolution plugin, i think it
remembers the filename of the impulse response that was previously
selected but it doesnt seem to load it.

thanks.
