Are they? See below.

According to the slightly skewed view of the FSF, even the former could be a
violation: 
  
  If the program dynamically links plug-ins, and they make function calls to
  each other and share data structures, we believe they form a single program,
  which must be treated as an extension of both the main program and the
  plug-ins. This means that combination of the GPL-covered plug-in with the
  non-free main program would violate the GPL. However, you can resolve that
  legal problem by adding an exception to your plug-in's license, giving
  permission to link it with the non-free main program.

Quotint the GPL-FAQ. However applied to LADSPA this would mean, that
GPL-plug-ins are not allowed in commercial software *at all*, and this would
also be the case for e.g. Renoise, even when it doesn't ship the plugins, but 
uses the system-wide installed plugins. 

So if Beat Kangzs isn't allowed to load swh-plugins, then Renoise wouldn't be
allowed neither, as far as I understand it. And Renoise does load them, I just
checked. So we'd have another violation alert for Renoise. Happy hunting. :)
