True, if they have done any modifications to that "external" part. If
it's only using it (jmusic?) as a library, the license of the library
shouldn't affect the main software. But this has always been a hot topic
with GPL: how to link dynamic / static and how does linking affect the
license of the linkee.

There is no statement about GPL on the Impro-visor site nor could I find
such a statement in the archive.org copies of previous pages. Wikipedia
states it's GPL as does http://www.softsynth.com/links/java_music.html
but .. has the copyright holder(s) ever declared it as GPL? Furthermore,
as I said in my previous post: the copyright holders are free to stop
using GPL. You may fork if you receive GPL licensed source from the
authors or from a previous licensee (someone who made a copy while it
was under GPL with the licenses intact etc.). You however may not fork
it based on a disassembled code not released under GPL.

Maybe I've missed something crucial in this discussion, so I'll ask the
stupid question (directed towards Raymond):

  Was the impro-visor version 3.99 released under GPL?
  
  .. or

  Are you assuming the whole of Impro-visor is subject to GPL as it has
violated the GPL of jmusic?
