Wait a minute, aseqdump shows almost all the information you need to fill the
ecasound parameters properly. After the "Control change" text, you find
three columns:
* First column (under "Ch") is the channel number, starting from 0. MIDI
channels are usually numbered from 1 thru 16, but this program shows it
starting from 0, and up to 15, so you need to add 1 to the channel number
when using it on Ecasound.
* Next one, under "_Data_", is the controller number. MIDI controllers range
goes from 0 to 127. Each controller number means something, where 1 means
"modulation", 7="volume",...
* Last column, also under "_Data_", is the controller value, or amount. This
value changes while you move the fader, stick, or button on your MIDI device.

Ecasound syntax for MIDI continuous controllers is:
-km:fx-param,start-value,end-value,controller,channel
The number(176) displayed by gmidimon is the decimal value of the status byte
for the controller message (0xB0 in hex) and means that it is just a
controller message on channel 0. This program also displays MIDI channels
starting from 0 instead of 1. The 'Data1' column shows the controller number
(1), and 'Data2' shows the controller amount (54). Your command line could
be: "-km:1,0,1000,1,1"
> What am I doing wrong ? And why the midi monitoring is so erratic ?
Yes, you are being a bit erratic switching from one program to another
without stopping to learn what means the output of each one.
