[linux-audio-user] dssi: 2 questions

[emanuele ..:: www.rumoridifondo.com ::..]

hi folks,
i've installed rosegarden on my mandriva 2006. then i've download dssi 
from "thac's rpm" (www.mde.djura.org/index2006.0.html). in particular 
i've installed these files:

dssi-0.9.1-0.1.20060mde.i586.rpm
dssi-vst-0.3.1-10.mdk2006.0.mde.i586.rpm
libdssi0-0.9.1-0.1.20060mde.i586.rpm
libdssi-vst0-0.3.1-10.mdk2006.0.mde.i586.rpm
libfluidsynth-dssi0-0.9.1-0.1.20060mde.i586.rpm
liblo0-0.22-0.1.20060mde.i586.rpm

after the installation process ended, i've read the file 
"/usr/share/doc/dssi-0.9.1/README".
i've run first jack and then "less_trivial_synth", "trivial_sampler" and 
"jack-dssi-host less_trivial_synth.so".
my dssi-path was set by default and so all these plugins started (i saw 
this by looking on jack connections) and i managed also to play 
"less_trivial_synth" by my m-audio keystation. i've managed also to rec 
and play with rosegarden.

the problem is that in all the cases, the gui of these soft-synth 
doesn't appear!

how can i solve the problem?

thank you
bye
