Hi Rafa,

I'm not a plugin developer so I can't comment on the best workflow. I can say that I'd try use a more lightweight host than Ardour. Have you tried running your plugin using the example jack host that comes with the LV2-core source?

<shameless self-promotion>
In case your intrested: I've written a simple C++ host class, in case you want to write a host specifically for testing purposes: https://github.com/harryhaaren/Lv2Host

Are you documenting what your doing in a blog or so?
I'm hoping to get writing LV2 plugins, but I've never found a "newbie" style tutorial..
Cheers, -Harry
