How about jack-dssi-host? $ DSSI_PATH=/usr/lib/ladspa jack-dssi-host guitarix_amp.so jack-dssi-host will then print out (among other things) its OSC path. Use this path with dssi_osc_send to set the plugin parameters (append '/control' to the path): $ dssi_osc_send osc.udp://youraddresshere.com:13160/dssi/guitarix_amp/guitarix_amp/chan00/control 5 -20 which sets control port 5 to -20. You can query the current state of the plugin: $ dssi_osc_update osc.udp://youraddresshere.com:13160/dssi/guitarix_amp/guitarix_amp/chan00 and don't forget analyseplugin to get the port numbers.
