<h3>Can I use LinuxSampler for commercial music production?</h3> |
| 192 |
|
<p class="default"> |
| 193 |
|
Hell, yes! Every indirect commercial usage of LinuxSampler, which essentially means |
| 194 |
|
using its audio output, can of course be used in commercial applications like music |
| 195 |
|
productions, live shows, etc. Don't get us wrong, with the mentioned commercial |
| 196 |
|
exception we don't want to restrict the normal user / musician, we just want to avoid |
| 197 |
|
somebody to directly make money with our work, that is by selling our software in a |
| 198 |
|
sampler product like a sampler + sample library bundle, a hardware sampler or |
| 199 |
|
something equivalent, at least not without giving something back to the open source |

<h3>LinuxSampler is not open source, you are evil!</h3> |
| 205 |
|
<p class="default"> |
| 206 |
|
There are of course many definitions of the term "open source", but according to the |
| 207 |
|
<a href="http://en.wikipedia.org/wiki/Open_source">definition on Wikipedia</a> |
| 208 |
|
LinuxSampler is in fact open source, since you've got complete access to its source |
| 209 |
|
code. So due to this fact, a normal user / musician is free to do with LinuxSampler |
| 210 |
|
what he likes to do, he can even adjust and tweak every single part of the software |
| 211 |
|
by modifying and compiling its source code. And just the fact that we want to avoid |
| 212 |
|
our work to be directly exploited in commercial software or hardware products is |
| 213 |
|
definitely not an "evil" intention. For the normal user / musician the commercial |
| 214 |
|
restriction is even an advantage, since that way commercial actors are forced to |
| 215 |
|
support this or another open source project either directly by coding or indirectly |
| 216 |
|
by funding and thus increase development speed. |

<h3>Will LinuxSampler turn closed-source?</h3> |
| 221 |
|
<p class="default"> |
| 222 |
|
No, LinuxSampler will remain open source. Again, the commercial exception is just to |
| 223 |
|
prevent commercial exploitation by third parties that haven't contributed anything to |
| 224 |
|
open source projects. |

<h3>I've heard the commercial exception of LinuxSampler was added at a certain version?</h3> |
| 229 |
|
<p class="default"> |
| 230 |
|
No, the commercial exception in LinuxSampler's license terms were there since day one. |
| 231 |
|
Even further it's not only there since the very first publicly available CVS |
| 232 |
|
(developer) version of LinuxSampler, that commercial exception was even already in |
| 233 |
|
Benno Senoner's proof of concept code called "EVO", which LinuxSampler was based on. |
| 234 |
|
There was even a rumour that we would have manipulated CVS history to "pretend" this |
| 235 |
|
exception wasn't added at a later point. Needless to say that this rumour is completely |
| 236 |
|
false as well. Think about it! We're a group of developers spread around the world who |
| 237 |
|
work on this project for fun and ideology in our spare time. Most of us contributed to |
| 238 |
|
various other open source / free software projects. Do you seriously think we would |
| 239 |
|
cheat on such an issue? Beside that you certainly find various people completely |
| 240 |
|
unrelated to this project who still have early versions of LinuxSampler and / or EVO |
| 241 |
|
and thus can confirm that this commercial exception was always there. |

<h3>Doesn't LinuxSampler illegally link against libgig?</h3> |
| 246 |
|
<p class="default"> |
| 247 |
|
No! LinuxSampler does not "illegally" link against libgig, since the copyright holder |
| 248 |
|
(in this case of libgig) has all rights of his work and thus is not bound to his own |
| 249 |
|
license terms. The sole purpose of license terms is to grant other people certain |
| 250 |
|
rights to use the work. |

<h3>Doesn't LinuxSampler illegally link against other libraries?</h3> |
| 255 |
|
<p class="default"> |
| 256 |
|
No, the only library LinuxSampler links to that has license restrictions regarding |
| 257 |
|
linking is libgig (<a href="#ls_breaking_libgig_license">see above</a>). Especially |
| 258 |
|
LinuxSampler does not break Qt's license terms, since it does not link against Qt at |
| 259 |
|
all. |

Usually LS gives you a meaningful error message in case it |
| 463 |
|
failed to load an instrument. However there might be rare |
| 464 |
|
cases where LS cannot resolve the reason and you get an |
| 465 |

error message like above. In this case make sure security / |
| 466 |

Usually most of those settings are set to "unlimited" on |
| 472 |

most boxes. If this is not the case on yours, make sure that |
| 473 |
|
at least the limits for "max locked memory", "virtual |
| 474 |
|
memory" and "data seg size" are sufficiently high enough. |
| 475 |
|
The exact value depends on the instruments you want to load. |
| 476 |
|
If your security policy allows it, you could simply set |
| 477 |
|
those limits to "unlimited" (see also config file |
