Great thanks I'll take look, something to generate the lv2 manifest from
json sounds good!

Maybe this is useful: https://github.com/milasudril/lv2plug/blob/master/

It takes a JSON file containing properties needed to describe an LV2 plug,
and generates a C++ include file. There is also a companion script that
generates the lv2 manifest from the same file. The class generated by the
php script, is used to instanciate the portmap
https://github.com/milasudril/lv2plug/blob/master/portmap.hpp. The portmap
is then used from

template<class Client> void portConnect(LV2_Handle handle,uint32_t port,void*

https://github.com/milasudril/lv2plug/blob/master/client.hpp, which is the
module that interfaces with the host.

The system works well for audio and control ports. Atom (MIDI) ports are
also connected to the correct pointer type, but atoms themselfs are void
pointers, so the type safety does not go further than const correctness. If
possible, I would like to fix this, within the Zero Overhead Abstraction
Principle, but I do not know how.
