i know that our ladspa-gui discussions have floundered, but i thought
this was an interesting point (confirming what some people have said,
and disputing other's opinions):

imho a major problem here is that most (all ?) hosts don't provide a
way to access the standard interface when the plugin has its own
editor. in effect, nobody has a real motivation to implement the
'string' interface correctly.

the most important argument to support the string interface is that the
editor is just a GUI, the user can see and manipulate it, while the
string interface (ideally in combination with VstParameterProperties)
provides an abstracted, logical interface to the parameters.

in my vst-host implementation for beos I export the parameters a plugin
provides as a 'parameter-web', which is a sophisticated set of classes
to allow any application to browse, display and/or automate parameters
of any 'controllable' media entitity (the same mechanism is used to
configure e.g. sound cards or the system mixer). so I don't have to
build automation or MIDI control of parameters into the host, I export
the needed information and let 'specialists' do the job.

for this to work, the plugins should provide as much information about
their parameters as possible. but even the string interface alone
doesn't provide much info, that's why I'd love to see developers make
some use use of the VstParameterProperties interface.

I could imagine that would also help other hosts to implement more
sophisticated parameter automation and the like...
