Hi

I wrote a new LV2 mini host,

*Why?*

The LV2 ecosystem has many excellent hosts =E2=80=94 from full DAWs to mod=
ular=20
environments.
However, in most of them the LV2 hosting logic is deeply embedded inside=
=20
large and complex code-bases.

Luma keeps the core hosting logic simple and visible, making it easy to=20
read and understand how LV2 hosting actually works, strongly separated=20
from any widget toolkit or audio/midi engine in use.

*What it supports*

  * Multi-instance LV2 plugin hosting
  * LV2 plugins with X11 / GTK2 UIs
  * Preset load and save
  * LV2 state store and restore
  * Shared worker thread
  * Shared UI thread
  * Terminal NO-GUI mode
  * Debug build with DummyEngine

*Typical uses*

  * learning how LV2 hosting works
  * debugging LV2 plugins
  * testing LV2 extensions
  * running plugins headless
  * building your own experimental LV2 hosts

here you go: https://github.com/brummer10/Luma

regards

hermann
