Hola Luis,
Creo que puede venir muy bien tener el linuxsampler como dssi con interfaz gráfica
Algo he hecho mal o algo no funciona. He compilado sin errores y parece que se ha instalado bien:
$locate ls16
/usr/local/lib/dssi/ls16
/usr/local/lib/dssi/ls16.so
/usr/local/lib/dssi/ls16/ls16_gui
/usr/local/share/ls16
/usr/local/share/ls16/stylesheets
/usr/local/share/ls16/stylesheets/Burgundy
/usr/local/share/ls16/stylesheets/HighContrast
/usr/local/share/ls16/stylesheets/Metal
/usr/local/share/ls16/stylesheets/Burgundy/ls16.qss
/usr/local/share/ls16/stylesheets/HighContrast/ls16.qss
/usr/local/share/ls16/stylesheets/Metal/ls16-logo-Metal.png
/usr/local/share/ls16/stylesheets/Metal/ls16.qss
/usr/local/share/ls16/stylesheets/Metal/pan-scale.png
/usr/local/share/ls16/stylesheets/Metal/volume-scale.png
$ echo $DSSI_PATH
/usr/lib/dssi/:/usr/local/lib/dssi
Pero no aparece en Rosegarden ni en qtractor y además:
$ jack-dssi-host /usr/local/lib/dssi/ls16.so
Cannot find DSSI or LADSPA plugin at '/usr/local/lib/dssi/ls16.so'
jack-dssi-host: Error: Failed to load plugin library "/usr/local/lib/dssi/ls16.so"
Saludos, Pablo
