198                            No, LinuxSampler will remain open source. Again, the commercial exception is just to
199                            prevent commercial exploitation by third parties that haven't contributed anything to
200                            open source projects.

204                            <h3>I've heard the commercial exception of LinuxSampler was added at a certain version?</h3>
205                            <p class="default">
206                            No, the commercial exception in LinuxSampler's license terms were there since day one.
207                            Even further it's not only there since the very first publicly available CVS
208                            (developer) version of LinuxSampler, that commercial exception was even already in
209                            Benno Senoner's proof of concept code called "EVO", which LinuxSampler was based on.
210                            There was even a rumour that we would have manipulated CVS history to "pretend" this
211                            exception wasn't added at a later point. Needless to say that this rumour is completely
212                            false as well. Think about it! We're a group of developers spread around the world who
213                            work on this project for fun and ideology in our spare time. Most of us contributed to
214                            various other open source / free software projects. Do you seriously think we would
215                            cheat on such an issue? Beside that you certainly find various people completely
216                            unrelated to this project who still have early versions of LinuxSampler and / or EVO
217                            and thus can confirm that this commercial exception was always there.

221                            <h3>Doesn't LinuxSampler illegally link against libgig?</h3>
222                            <p class="default">
223                            No! LinuxSampler does not "illegally" link against libgig, since the copyright holder
224                            (in this case of libgig) has all rights of his work and thus is not bound to his own
225                            license terms. The sole purpose of license terms is to grant other people certain
226                            rights to use the work.

230                            <h3>Doesn't LinuxSampler illegally link against other libraries?</h3>
231                            <p class="default">
232                            No, the only library LinuxSampler links to that has license restrictions regarding
233                            linking is libgig (<a href="#ls_breaking_libgig_license">see above</a>). Especially
234                            LinuxSampler does not break Qt's license terms, since it does not link against Qt at
235                            all.

438                                    Usually LS gives you a meaningful error message in case it
439                                    failed to load an instrument. However there might be rare
440                                    cases where LS cannot resolve the reason and you get an
