I should have attached that in my first link!

In their FAQ:
- LV2 is planned for the next version (nice!)
- LADSPA is not planned for the moment (make sense if they support LV2)

Bitwig seem to be designed to be able to jam with loop of your own creation, similarly to what's available in Ableton Live - this is something I'm always missing in Linux, being able to easily and quickly trying out different loop combination with different order to find out the best composition possible.
