Hey!
Tried it out in Qtractor as LADSPA. It has no presets, of course.
Anyway, I couldn't get the sound I wanted. maybe it is ok for small room effects, but I could not get the cathedral sound.
Maybe it is not a correct method to test a reverb or maybe I am not that good in tweaking reverbs )

Would be nice to know other people's experience with LADSPA!
