Dynamic plugin structure:
------------------
It was asked if plugins would have parameters (and I/Os) that would change
at runtime. It was pointed out that several existing APIs allow IO configs
to change at run time.
A modular model was proposed, where the plugin defines 1 or more static
module classes. The module classes can then be instantiated in the running
plugin. A change such as this is not an automatable change, and is not a
realtime operation. It can be thought of as akin to a plugin
destroy/re-create process.
It was pointed out that DXi requires the host to confirm that a
plugin-initiated structural change is allowed. It was suggested that the
plugin might also need to confirm a host-initiated structural change.
Use cases for this included a modular synth/effect, a mixer, and complex VA
synths (which would otherwise have hundreds of parameters).
Q: is it required to support dynamic plugin structures, and thereby a
dynamic parameter list?
