Spark Xl Au Plugs In Other Hosts, im having problems loading them Options

[stamrfar]

hi i have spark xl and i tried to load the plugins in sound track but the app
unexpetedly quits
is this a spark xl problem or soundtrack problem?
should this be possible or can i only use the audio units plugs in spark itself?
im getting my audio units upgrade for digital performer 4 soon as well...
wonder if it will work there.......
