Hi Jamie. I'll try trivial_synth, but just a bit of an update. I'd botched the 
syntax for starting fluidsynth, forgetting to put fluidsynth-dssi to run it. 
Got that up, and it asked for a soundfont, so I put the same one in it that's 
loaded into the soundcard, and this does work ok. Test sound works, and 
keyboard plays ok. Both Hextor and Xsynth show they have sounds installed, 
but don't play them. I've DL'd some dx7 patches for Hextor. I think I'll 
import them and see if they will play. LADSPA and all of it's plugins are 
installed, but I can't remember using them up to now. It was enough of a 
hassle getting to record something on Rosegarden without adding effects to 
it. I know absolutely nothing about PD, but will certainly look at it. Thanks 
for the help. Nigel.
