/* @drobilla: Does it make sense to re-instantiate all plugins
* whenever the buffersize changes?
* Is there a way to find plugins that require the min/max blocksize option?
/* Consider updating max-block-size whenever the buffersize changes.
* It requires re-instantiating the plugin (which is a non-realtime operation),
* so it should be done lightly and only for plugins that require it.
*
* given that the block-size can change at any time (split-cycles) ardour currently
* does not support plugins that require bufz_fixedBlockLength.
