168                          <p class="default">                          <p class="default">
169                                  There are currently four subprojects in the LinuxSampler project; linuxsampler,                          Hell, yes! Every indirect commercial usage of LinuxSampler, which essentially means
170                                  qsampler, libgig and liblscp. linuxsampler is the core of the sampler, it includes the                          using its audio output, can of course be used in commercial applications like music
171                            productions, live shows, etc. Don't get us wrong, with the mentioned commercial
172                            exception we don't want to restrict the normal user / musician, we just want to avoid
173                            somebody to directly make money with our work, that is by selling our software in a
174                            sampler product like a sampler + sample library bundle, a hardware sampler or
175                            something equivalent, at least not without giving something back to the open source
176                            Community.

180                            <h3>LinuxSampler is not open source, you are evil!</h3>
181                            <p class="default">
182                            There are of course many definitions of the term "open source", but according to the
183                            <a href="http://en.wikipedia.org/wiki/Open_source">definition on Wikipedia</a>
184                            LinuxSampler is in fact open source, since you've got complete access to its source
185                            code. So due to this fact, a normal user / musician is free to do with LinuxSampler
186                            what he likes to do, he can even adjust and tweak every single part of the software
187                            by modifying and compiling its source code. And just the fact that we want to avoid
188                            our work to be directly exploited in commercial software or hardware products is
189                            definitely not an "evil" intention. For the normal user / musician the commercial
190                            restriction is even an advantage, since that way commercial actors are forced to
191                            support this or another open source project either directly by coding or indirectly
192                            by funding and thus increase development speed.

196                            <h3>Will LinuxSampler turn closed-source?</h3>
197                            <p class="default">
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.

203                            <a name="ls_license_change"></a>
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.
