You have LinuxSampler listed as GPL licensed, but it's actually source-available proprietary software. From http://www.linuxsampler.org/downloads.html http://www.linuxsampler.org/downloads.html: "LinuxSampler is licensed under the GNU GPL with the exception that USAGE of the source code, libraries and applications FOR COMMERCIAL HARDWARE OR SOFTWARE PRODUCTS IS NOT ALLOWED without prior written permission by the LinuxSampler authors." This directly contradicts the GPL v2.0 (the relevant version): "You may not impose any further restrictions on the recipients' exercise of the rights granted herein." Of course the copyright holders have the right to impose whatever self-contradictory license they like, but this combination isn't GPL and it isn't Open Source.
