I'm pretty clueless about how midi works. I once did a quick test and 
(if my memory serves me well) I (think) used this to control the volume 
and pan (via ecasound and a wheel on my midi keyboard). If this is true, 
then I believe you can control other ecasound effects via midi. Someone 
please correct me if I'm completly off the mark. I hate showing my 
ignorance, but I also hate seeing useful features not being used...

 From the ecasound man page...

  MIDI continuous controller (control change messages). Messages on the 
MIDI-channel 'channel' that are coming from controller number 
'controller' are used as the controller source. As recommended by the 
MIDI-specification, channel numbering goes from 1 to 16. Possible 
controller numbers are values from 0 to 127. The MIDI-device where bytes 
are read from can be specified using -Md option. Otherwise the default 
MIDI-device is used as specified in ~ecasound/ecasoundrc (see 
ecasoundrc(5)). Defaults to /dev/midi.
