It seems to be a request popping out quite often on this list; I personally
prefer to use my dist pedals because dist/OD are tricky effects
sometimes. Anyway, for OD's you might like to have a look at some ladspa
pluging: there's a link to Steve Harris' page there
where you'll find out an OD effect along with a lot of other exciting
plugins. Note that what people sometimes refer to as distortion is just
compression in fact (especially for drums), ecasound has two compressors
on its own (see manpage)

That's what an EQ is, the only difference is that normal EQs found on music
gear and stereos have predefined parameters, with ecasound you're the boss,
it's even better than a parametric EQ though it requires more efforts to set
up but, hey, freedom always comes at a certain cost!
(If you'd just like a simple EQ you'll find one in Steve Harris' plugins as well.)

As far as I can tell that's quite right. However I suggest using the effect
presets for that as it does the trick much more nicely; rewriting your example:
my_eq = -efb:165,85 -ea:120 | -efb:475,225 -ea:80 | -efb:10400,9600 -ea:200
(note that the only frequencies heard now will be the one you have allowed
to pass through, maybe you should add a high and lowpass filter to allow both
ends of the range to pass through unmolested)

I believe so, I'm sure someone will correct me if I made a mistake. :)
