dssi is basically an API that adds some extra functionality on top of
LADSPA, namely OSC, usually via a GUI, and MIDI. The plugins require a
host to manage communication between the GUI and the plugin, and
connection to audio and midi drivers (usually jack/alsa). If you launch
a plugin via your Gnome menu or whatever, it will launch jack-dssi-host
as the host. For diagnostics, I recommend that you run this manually
from the command line with:

jack-dssi-host -v yourplugin.so

This will give verbose output, and perhaps a better clue as to what the
problem is.

Also, do you get any audio when clicking on the "send test note" button
in the GUI? If not, the verbose flag will tell you whether the midi
request is reaching the host or not.
