208                            <h3>Can I use LinuxSampler for commercial music production?</h3>
209                            <p class="default">
210                            Hell, yes! Every indirect commercial usage of LinuxSampler, which essentially means
211                            using its audio output, can of course be used in commercial applications like music
212                            productions, live shows, etc. Don't get us wrong, with the mentioned commercial
213                            exception we don't want to restrict the normal user / musician, we just want to avoid
214                            somebody to directly make money with our work, that is by selling our software in a
215                            sampler product like a sampler + sample library bundle, a hardware sampler or
216                            something equivalent, at least not without giving something back to the open source
217                            Community.
218                            </p>
219    
220                            <a name="open_source"></a>
221                            <h3>LinuxSampler is not open source, you are evil!</h3>
222                            <p class="default">
223                            There are of course many definitions of the term "open source", but according to the
224                            <a href="http://en.wikipedia.org/wiki/Open_source">definition on Wikipedia</a>
225                            LinuxSampler is in fact open source, since you've got complete access to its source
226                            code. So due to this fact, a normal user / musician is free to do with LinuxSampler
227                            what he likes to do, he can even adjust and tweak every single part of the software
228                            by modifying and compiling its source code. And just the fact that we want to avoid
229                            our work to be directly exploited in commercial software or hardware products is
230                            definitely not an "evil" intention. For the normal user / musician the commercial
231                            restriction is even an advantage, since that way commercial actors are forced to
232                            support this or another open source project either directly by coding or indirectly
233                            by funding and thus increase development speed.

237                            <h3>Will LinuxSampler turn closed-source?</h3>
238                            <p class="default">
239                            No, LinuxSampler will remain open source. Again, the commercial exception is just to
240                            prevent commercial exploitation by third parties that haven't contributed anything to
241                            open source projects.
242                            </p>
243    
244                            <a name="ls_license_change"></a>
245                            <h3>I've heard the commercial exception of LinuxSampler was added at a certain version?</h3>
246                            <p class="default">
247                            No, the commercial exception in LinuxSampler's license terms were there since day one.
248                            Even further it's not only there since the very first publicly available CVS
249                            (developer) version of LinuxSampler, that commercial exception was even already in
250                            Benno Senoner's proof of concept code called "EVO", which LinuxSampler was based on.
251                            There was even a rumour that we would have manipulated CVS history to "pretend" this
252                            exception wasn't added at a later point. Needless to say that this rumour is completely
253                            false as well. Think about it! We're a group of developers spread around the world who
254                            work on this project for fun and ideology in our spare time. Most of us contributed to
255                            various other open source / free software projects. Do you seriously think we would
256                            cheat on such an issue? Beside that you certainly find various people completely
257                            unrelated to this project who still have early versions of LinuxSampler and / or EVO
258                            and thus can confirm that this commercial exception was always there.

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

272                            <p class="default">
273                            No, the only library LinuxSampler links to that has license restrictions regarding
274                            linking is libgig (<a href="#ls_breaking_libgig_license">see above</a>). Especially
275                            LinuxSampler does not break Qt's license terms, since it does not link against Qt at
276                            all.
