Ok, here's the vocoder. I had lots of fun with the following ecasound
script:
--cut--
#!/bin/sh
ecasound -c \
-a:bus1 -f:16,1,44100 -i amen.ewf -eac:0,2 \
-a:bus2 -f:16,1,44100 -i /dev/dsp -erm:2 -eac:0,1 \
-a:bus1,bus2 -f:16,2,44100 -o loop,1 \
-a:bus3 \
-f:16,2,44100 -i loop,1 \
-f:16,2,44100 -o /dev/dsp \
-el:vocoder,6,0.7,1,1,1,1,0.8 -eac:0,2 -ea:1000
--cut--
Warning!!! Be careful with the volume levels. I had to add -ea:1000
(yup, that's 1000% amplify) to hear the results, but
this also produces _nasty_ blasts of noise when
starting ecasound (something wrong with the loop dev code
I think)
'amen.ewf' is the classsic amen drumloop (looping enabled in ewf) Now then
just plug your guitar (or whatever you have connected to line in) and
start controlling the drumloop. This is especially fun with a heavily
distorted guitar sound... :)

I have released version 0.1 of the LADSPA vocoder plugin I spoke of
before. You can find it at:
http://www.c0nfusion.org/~josh/
The original program that was shamelessly ripped from can be found at:
http://www.uni-karlsruhe.de/~uno4/linux/
If you don't know what a vocoder is: its an effect commonly used to add
a robotic effect to vocals. Settel's site (the original vocoder author)
has a more in depth description.
Its my first LADSPA plugin so let me know if you find any problems or
have some better ideas about the design.
