The controller numbering starts from 0 and ends at 127. The same
convention is used in the MIDI spec, and by most/many MIDI devices. IOW,
the numbers in your synth's manual should work.

Ecasound only supports raw MIDI-devices, not MIDI-ports of the ALSA
sequencer subsystem. You can get around this by using ALSA's snd-virmidi

ports can be accessed by virtual MIDI-devices /dev/snd/midiCXDY, where X
is the card number of the snd-virmidi module, and Y a number deriver from
the sequencer client id. To make Ecasound use these, add the
