Ah, I didn't read carefully: I thought, all that was built was
supposed to work. Nevermind.

There are different output ranges in use. Especially if you once used
Csound this is annoying. I now looked, what ladspa.h has to say about
this. At the "typedef float LADSPA_Data;" it says:
For audio it is generally assumed that 1.0f is the `0dB' reference
amplitude and is a `normal' signal level.
So with LADSPA signals indeed should have a 1.0 amplitude at full
volume.
ciao
