Ok, here's undoubtly the biggest and meanest LADSPA plugin so far! :)
You'll need the current CVS-version of ecasound, because this plugin
(with over 50 parameters!) triggered a bug in ecasound's LADSPA support.
For a slightly easier way to test this, here's a ready-to-use
ecasound effect preset:

hermes.ecp:
--cut--
hermes = -el:hermesFilter,3,0,0.27,1,100,1,40,1,1.5,1,2,-4,-4,-50,-20,-20,-20,200,1000,3,1,3,5,1500,0.65,0,130,0,5,400,0.8,0,0,-177,1,150,0.9,0.97,30,30,0.025,0.9,0.5,0.05,0.7,0.5,0.1,0.5,0.5,0,-20,-20
--cut--

ecasound -i somefile.wav -o /dev/dsp -pf:hermes.ecp

PS This basicly emulates a small analogue synth (and sure sounds like it!)...

Hi all, I've just finished a new plugin, its in the snapshot, but I
haven't released it properly, because. 1, it's not fully tested, some extreme
settings will cause cliping. 2, it's only one plugin, other changes have
only been XML cleanups etc. 3. it's really hard to use at the moment, it has
a lot of parameters (52), and working them on a command line is not fun.

Theres a block diagram at http://inanna.ecs.soton.ac.uk/plugins/hermes.png

Theres a prize for anyone who can guess why it's called hermes ;) I 
normally believe in calling a spade a spade, but calling a twin oscilator
modulator with crossover, distortion, filters and delays a [one of those]
is a bit silly.

Values that actually do something audible are:
3 0 0.27 1 100 1 40 1 1.5 1 2 -4 -4 -50 -20 -20 -20 200 1000 3 1 3 5 1500
0.65 0 130 0 5 400 0.8 0 0 -177 1 150 0.9 0.97 30 30 0.025 0.9 0.5 0.05
0.7 0.5 0.1 0.5 0.5 0 -20 -20

But to hear it in applyplugin you will need:
applyplugin any-old-crap.wav foo.wav ./hermes_filter_1200.so
hermesFilter 3 0 0.27 1 100 1 40 1 1.5 1 2 -4 -4 -50 -70 -70 -70 200 1000
3 1 3 5 1500 0.65 0 130 0 5 400 0.8 0 0 -177 1 150 0.9 0.97 30 30 0.025
0.9 0.5 0.05 0.7 0.5 0.1 0.5 0.5 0 -20 -20 ./amp_1181.so amp 90

It takes about 90-100 PIII MHz when running, but sounds really nice.

More soon,
   Steve
