plate 2x2

Anything that doesn't fit into other topics goes here!
hi all,
where can I find the "plate 2x2" plugin?
I just installed lmms, and the "demo projects" give an error that this plugin is missing, but I can't find it.
(lmms-1.1.3 compiled from source on slackware13.37)
plate is one of the default plugins
it is placed in your LADSPA folder and named 'plate_1423.dll'
Look for it there. If you dont have that dll, something was missing in your download
Did you get that from the official site?

AND
are you using an official release or a pre-release -only 1.1.3 is guaranteed for production, the 1.1.3zxy is not
