Hmm, when trying out new effects, I usually try drumloops first. Human
voice is also good material for effects (it's easier to notice what
is being altered). One problem with Hermes is that it really sounds
strange. It models an old Swiss analog synth, so don't expect to get
digital clarity. :)
But, but, have you tried with applyplugin (that comes with LADSPA
toolkit)? By doing this, you can make sure that ecasound is working
properly. Another thing to try is to tweak the parameters. For instance,
set the last three parameters to zero. Another set of useful parameters is
the waveform selectors...

Hmm, don't no about you, but I wouldn't give up my rack gear, no matter
how good effects I have on the computer. It's just so different. Btw;
what do you think about the "imitate-hardware-as-closely-as-possible"
approach that seems so dominant in the mac/win audio world. Here's
a very good example, Propellerheads' Reason:
Now to be honest, I couldn't picture myself working with this kind of
computer-sw. What do you think?

Well, that's about it really. And for most plugins, the parameter
descriptions are enough, but of course for the more complex plugins,
documentation would help. But you must remember, that we are not talking
about commercial plugins here. Like with free-sw apps, authors tend to be
lazy doc writers. But this isn't necessarily bad, as you also have the
same benefits as with free-sw. For instance, if you spend lots of time
studying some LADSPA plugin, you could sum up your experiences and
write a short document yourself. When more people do this, we'd have
more and more docs available. Making some good presets (based on the
plugins) is another way to share your knowledge.
And of course, a very big plus for LADSPA plugins, you can contact
the author yourself! He'll probably be glad to answer your
