127                          LinuxSampler is a work in progress. The goal is to produce a free, open source pure software audio sampler                          The LinuxSampler proect was founded / established / formed with the

130                          <br>                          commercial Windows/Mac software samplers
131                          LinuxSampler was designed as a sampler backend, decoupled from any user interface. It provides a native C++                          and to introduce new features not yet available by any other
132                          <a href="http://en.wikipedia.org/wiki/Application_programming_interface">API</a> as well as a network interface                          sampler in the world.

134                          for controlling the sampler and managing sampler sessions. But don't be afraid, with QSampler (based on the  
135                          cross-platform C++ GUI library Qt) and JSampler (Java based, thus platform independent) we already have two convenient                          <h2>The Engine</h2>
136                          frontends for LinuxSampler and due to the                          <p class="default">
137                          decoupled design you can even control the sampler with the GUI frontend(s) from another computer, probably even running                          <u><b>LinuxSampler</b></u> was designed very modular, especially
138                          another OS like Windows or OS X. Beside our own custom network control layer we planned to add existing ones as well                          (and in contrast to other samplers) it was decoupled from any user
139                          (e.g. <a href="http://www.cnmat.berkeley.edu/OpenSoundControl/">OSC</a>). With the planned SMP and cluster support                          interface. LinuxSampler itself usually runs as own process in the

141                          <br>                          the screen, or at most it can be launched to show status
142                          It is planned to support all common sampler formats in LinuxSampler, but at the moment we chose to concentrate on the                          informations and debug messages in a console window:<br>
143                          Gigasampler format, because when we started this project, the Gigasampler format was (in our opinion) the most popular                          <br>
144                          and "best" sampler format in regards of quality and power, especially                          <a href="screenshots/ls_0_5_1_console.png">
145                          for the synthesis of natural instruments like pianos, brass and bowed instruments. But we already made good advance in                                  <img src="screenshots/ls_0_5_1_console_preview.png">
146                          implementing this format, so we are optimistic to start with adding other formats soon. Beside that we also planned to                          </a><br>
                         design our own, sophisticated sampler format to introduce a more powerful and more flexible sampler format compared to  
                         any sampler format currently available in the world. Be encouraged to share your ideas about such a new format with us!<br>  
147                          <br>                          <br>
148                          You might also want to read <a href="faq.html#aga">this FAQ</a> about explanations of the various subprojects.<br>                          That means LinuxSampler itself is the "engine" of the sampler, it
149                            is the software component which performs all the heavy and time
150                            critical computational tasks of handling MIDI events, calculating
151                            the audio data and sending the final audio data to your sound
152                            card(s). We call LinuxSampler the <i>sampler backend</i>.
153                            </p>
154    
155                            <h2>The Face(s)</h2>
156                            <p class="default">
157                            Obviously you need some way to control the sampler. That's where a
158                            2nd application comes into game, which we call a
159                            <i>sampler frontend</i> application. A frontend is (usually) a
160                            graphical application, visible on the screen, providing the user
161                            a set of e.g. menus, buttons, sliders, dials, etc. to allow the
162                            user to control the sampler in a convenient way. It merely sends
163                            the user requests to the sampler engine (LinuxSampler) and in turn
164                            shows the engine's status informations on the screen. A frontend
165                            does not perform any signal processing tasks, so you can see it as
166                            a "face" of the sampler.<br>
167                            <br>
168                            For luxury we already provide you two different frontends / "faces"
169                            for LinuxSampler:
170                            </p>
171                            <ul>
172                                    <li>
173                                    <u><b>QSampler</b></u> is a light-weight frontend written in
174                                    C++, using straightforward native graphical controls of the
175                                    underlying operating system. That way the appearance of
176                                    QSampler on the screen is very fast and it only consumes very
177                                    little resources. Due to its utilization of the operating
178                                    system's common GUI controls, it looks slightly different on
179                                    every operating system (also dependent of the user's selected
180                                    theme on his OS):<br>

192                                    <u><b>JSampler</b></u> is a full-fledged frontend for
193                                    LinuxSampler, written in Java and currently comes in two
194                                    flavors: <b>JSampler "Classic"</b> offers straightforward GUI
195                                    controls whereas <b>JSampler "Fantasia"</b> provides a modern
196                                    skin based user interface:<br>
197                                    <br>
198                                    <a href="screenshots/fantasia.png"><img src="screenshots/fantasia-preview.png"></a>
199                                    <br>
200                                    JSampler supports all features currently available in the
201                                    sampler engine (LinuxSampler).<br>
202                                    </li>
203                            </ul>
204                            <p class="default">
205                            It's completely up to you which frontend to use. You could even use
206                            both parallel at the same time for the same sampler engine
207                            instance, really! ;-)
208                            </p>
209    
210                            <h2>The Format</h2>
211                            <p class="default">
212                            It is planned to support all common sampler formats in
213                            LinuxSampler, but at the moment we chose to concentrate on the
214                            Gigasampler format, because when we started this project, the
215                            Gigasampler format was (in our opinion) the most popular
216                            and "best" sampler format in regards of quality and power,
217                            especially      for the synthesis of natural instruments like pianos,
218                            brass and bowed instruments. But we already made good advance in
219                            implementing this format, so we are optimistic to start with
220                            adding other formats soon. Beside that we also planned to
221                            design our own, sophisticated sampler format to introduce a more
222                            powerful and more flexible sampler format compared to
223                            any sampler format currently available in the world. Be encouraged
224                            to share your ideas about such a new format with us!
225                            </p>
226    
227                            <h2>The Editor</h2>
228                            <p class="default">
229                            <u><b>gigedit</b></u> allows you to edit and create instruments
230                            for the Gigasampler format, which can be used with LinuxSampler
231                            as well as with Tascam's Gigastudio. Following our line of
232                            modularity we also made the instrument editors independent
233                            applications. Because let's face it: every sampler format is
234                            different, so in our opinion it is better to honor the specific
235                            features of one format with its own instrument editor application
236                            instead of trying to fiddle everything into one single bloated
237                            application. So gigedit is our first editor, dedicated to the .gig
238                            format:<br>
239                            <br>
240                            <a href="screenshots/gigedit_0_0_3.png"><img src="screenshots/gigedit_0_0_3_preview.jpg"></a>
241                            <br>
242                            You can use gigedit as stand-alone application or in conjunction
243                            with LinuxSampler. For the latter case gigedit installs a plugin
244                            into the sampler engine, so the engine (and with it the frontends)
245                            knows that gigedit actually exists and can handle the .gig format.
246                            So even though we decoupled the sampler's components into
247                            independent applications, they all work seamlessly together. Just
248                            press the "Edit" button on a channel strip of a frontend and
249                            gigedit will automatically popup on the screen and you're
250                            immediately ready to edit your selected instrument, making all your
251                            modifications audible in realtime. Even when editing huge
252                            instruments of 1GB or more, tweak the instrument with gigedit and
253                            immediately hear it while playing on the keyboard at the same time.
254                            And the good thing: even with new sampler formats we're going to
255                            add soon (and with it new editors), you don't have to remember
256                            which instrument you loaded uses which format. Simply click on
257                            "Edit" in a frontend and the sampler engine will choose the right
258                            instrument editor application for the respective instrument for
259                            you.
260                            </p>
261    
262                            <h2>The Technical Interface</h2>
263                            <p class="default">
264                            As the components of the sampler are independent applications,
265                            there must be a way to let the applications communicate with each
266                            other. For this LinuxSampler provides a native C++
267                            <a href="http://en.wikipedia.org/wiki/Application_programming_interface">API</a>
268                            as well as a network interface using an ASCII based protocol which
269                            we call "<a href="http://www.linuxsampler.org/api/draft-linuxsampler-protocol.html" title="LinuxSampler Control Protocol">LSCP</a>"
270                            for controlling the sampler engine and managing sampler sessions.
271                            Our frontends support that network interface, which also allwos
272                            control the sampler engine with the GUI frontend(s) remotely from
273                            another computer, probably even running a completely different
274                            Operating System.
275                            </p>
276    
277                            <h2>The Community</h2>
278                            <p class="default">
279                            All applications are under active development. However we all work
280                            on this project for fun in our spare time. There are still so many
281                            things to do and our hands are limited. So don't hesitate on
282                            participating to the project! You don't necessarily need to be a
283                            skilled programmer to help the project. Testing the applications,
284                            <a href="http://bugs.linuxsampler.org.">reporting bugs</a>, writing
285                            documentation, providing artwork, themes for frontends, etc. helps
286                            us and all users a lot! Simply subscribe to our
