Brian> My unbiased 3 paragraph summary of DFSG licenses:
Brian> The two major licenses that comply with the DFSG

Brian> license and the GPL style license.
Brian> The BSD style license generally are the most unrestrictive

Brian> are BSD licensed.
Brian> The GPL style license, as applied to this case, says if you
Brian> make modifications or make "derivative works" of it, then
Brian> the result must be licensed under the GPL (or similar
Brian> license). I don't know if a wav file created from a FreePat
Brian> file would be considered a "derivative work" or not. The
Brian> GPL also says if you distribute it, then you must also
Brian> distribute source code to (as appropriate to the file
Brian> format). I believe the GS fonts are GPL.
Brian> My biased opinions and questions for debian-legal:
Brian> There are other issues with the GPL that might effect
Brian> soundfont files, not sure. For instance, would the
Brian> soundfont file be considered "source code" when making a
Brian> *.wav file? What if the *.wav file has since been edited in

Brian> Also just like I expect to be able to type and print a

Brian> Personally, my opinion (depending on the above) would be to
