That could be a very wise solution, but there's one big problem with
it: when you load a LV2 plugin, you load only one plugin!
To be clearer I make an example: I have 10 VST plugin, and I want to
write a LV2 plugin which loads VST plugins. When the LV2-aware
application asks me which plugin I want to load I should specify the
VST plugin loader... but then? There's no way for my LV2 plugin to
determine which VST plugin it should load.
But also if this is an overcomeable problem, for each VST plugin I
load I have to waste memory space with a new instance of the LV2 VST
Then, it is quite absurde from the user point of view to open a plugin
which lets you open other plugins... it's just illogical!
Don't misunderstand me, LV2 is great, I think that it's the best
processing architecture out there, but it's designed with a 1:1
relationship in mind (one plugin = one effect). That's absolutely not
an LV2 weakness, it just does its job and nothing else (as it should
Here I'm talking about a different problem: interoperability beetween
different processing paradigms, letting the user choose what he likes
