131                          <h2>General</h2>                          <h2>The Project</h2>
132                            <p class="default">
133                            The LinuxSampler project was founded with the
134                            goal to produce a free, open source pure software audio sampler
135                            with professional grade features, comparable to both hardware and
136                            commercial Windows/Mac software samplers
137                            and to introduce new features not yet available by any other
138                            sampler in the world.
139                            </p>
140    
141                            <h2>The Engine</h2>
142                            <p class="default">
143                            <u><b>LinuxSampler</b></u> was designed very modular, especially
144                            (and in contrast to other samplers) it was decoupled from any user
145                            interface. LinuxSampler itself usually runs as own process in the
146                            background of the computer and usually does not show up anything on
147                            the screen, or at most it can be launched to show status
148                            informations and debug messages in a console window:<br>
149                            <br>
150                            <a href="screenshots/ls_0_5_1_console.png">
151                                    <img src="screenshots/ls_0_5_1_console_preview.png">
152                            </a><br>
153                            <br>
154                            That means LinuxSampler itself is the "engine" of the sampler, it
155                            is the software component which performs all the heavy and time
156                            critical computational tasks of handling MIDI events, calculating
157                            the audio data and sending the final audio data to your sound
158                            card(s). We call LinuxSampler the <i>sampler backend</i>.
159                            </p>
160    
161                            <h2>The Face(s)</h2>
162                            <p class="default">
163                            Obviously you need some way to control the sampler. That's where a
164                            2nd application comes into game, which we call a
165                            <i>sampler frontend</i> application. A frontend is (usually) a
166                            graphical application, visible on the screen, providing the user
167                            a set of e.g. menus, buttons, sliders, dials, etc. to allow the
168                            user to control the sampler in a convenient way. It merely sends
169                            the user requests to the sampler engine (LinuxSampler) and in turn
170                            shows the engine's status informations on the screen. A frontend
171                            does not perform any signal processing tasks, so you can see it as
172                            a "face" of the sampler.<br>
173                            <br>
174                            For luxury we already provide you two different frontends / "faces"
175                            for LinuxSampler:
176                            </p>
177                            <ul>
178                                    <li>
179                                    <u><b>QSampler</b></u> is a light-weight frontend written in
180                                    C++, using straightforward native graphical controls of the
181                                    underlying operating system. That way the appearance of
182                                    QSampler on the screen is very fast and it only consumes very
183                                    little resources. Due to its utilization of the operating
184                                    system's common GUI controls, it looks slightly different on
185                                    every operating system (also dependent of the user's selected
186                                    theme on his OS):<br>
187                                    <br>
188                                    <a href="screenshots/qs_0_2_1_win.jpg">
189                                            <img src="screenshots/qs_0_2_1_win_preview.jpg">
190                                    </a>&nbsp;
191                                    <a href="screenshots/qs_0_2_1_ubuntu.png">
192                                            <img src="screenshots/qs_0_2_1_ubuntu_preview.png">
193                                    </a><br>
194                                    <br>
195                                    Note however, QSampler does not fully support all features of
196                                    the sampler engine (LinuxSampler) yet. Most notably the
197                                    engine's instruments database feature is not yet covered by
198                                    QSampler. But if you don't need that particular feature,
199                                    you're certainly fine with QSampler as well.<br>
200                                    <br>
201                                    </li>
202    
203                                    <li>
204                                    <u><b>JSampler</b></u> is a full-fledged frontend for
205                                    LinuxSampler, written in Java and currently comes in two
206                                    flavors: <b>JSampler "Classic"</b> offers straightforward GUI
207                                    controls whereas <b>JSampler "Fantasia"</b> provides a modern
208                                    skin based user interface:<br>
209                                    <br>
210                                    <a href="screenshots/fantasia.png"><img src="screenshots/fantasia-preview.png"></a>
211                                    <br>
212                                    JSampler supports all features currently available in the
213                                    sampler engine (LinuxSampler). Also note that even though
214                                    JSampler is written in Java and slightly more hungry
215                                    regarding resources (compared to QSampler), this usually
216                                    does not have any impact on the audio rendering performance
217                                    of the sampler, since the engine runs completely independently
218                                    and with much higher CPU priority than the frontend(s).<br>
219                                    </li>
220                            </ul>
221                            <p class="default">
222                            It's completely up to you which frontend to use. You could even use
223                            both parallel at the same time for the same sampler engine
224                            instance, really! ;-) You're concerned that your sampler frontend
225                            might waste precious resources of your computer? No problem, just
226                            setup the sampler session for your needs and then quit the
227                            frontend application. The sampler engine doesn't care! It continues
228                            to do its job. You need to change something? Start the frontend
229                            again (or another frontend) and you see what you expect to see: the
230                            current setup and state of the running sampler engine.
231                            </p>
232    
233                            <h2>The Format</h2>
234                            <p class="default">
235                            It is planned to support all common sampler formats in
236                            LinuxSampler, but at the moment we chose to concentrate on the
237                            Gigasampler format, because when we started this project, the
238                            Gigasampler format was (in our opinion) the most popular
239                            and "best" sampler format in regards of quality and power,
240                            especially      for the synthesis of natural instruments like pianos,
241                            brass and bowed instruments. But we already made good advance in
242                            implementing this format, so we are optimistic to start with
243                            adding other formats soon. Beside that we also planned to
244                            design our own, sophisticated sampler format to introduce a more
245                            powerful and more flexible sampler format compared to
246                            any sampler format currently available in the world. Be encouraged
247                            to share your ideas about such a new format with us!
248                            </p>
249    
250                            <h2>The Editor</h2>
251                            <p class="default">
252                            <u><b>gigedit</b></u> allows you to edit and create instruments
253                            for the Gigasampler format, which can be used with LinuxSampler
254                            as well as with Tascam's Gigastudio. Following our line of
255                            modularity we also made the instrument editors independent
256                            applications. Because let's face it: every sampler format is
257                            different, so in our opinion it is better to honor the specific
258                            features of one format with its own instrument editor application
259                            instead of trying to fiddle everything into one single bloated
260                            application. So gigedit is our first editor, dedicated to the .gig
261                            format:<br>
262                            <br>
263                            <a href="screenshots/gigedit_0_0_3.png"><img src="screenshots/gigedit_0_0_3_preview.jpg"></a>
264                            <br>
265                            You can use gigedit as stand-alone application or in conjunction
266                            with LinuxSampler. For the latter case gigedit installs a plugin
267                            into the sampler engine, so the engine (and with it the frontends)
268                            knows that gigedit actually exists and can handle the .gig format.
269                            So even though we decoupled the sampler's components into
270                            independent applications, they all work seamlessly together.
271                            <a href="http://download.linuxsampler.org/doc/gigedit/quickstart/gigedit_quickstart.html#live_editing">
272                                    Just press the "Edit" button
273                            </a> on a channel strip of a frontend and
274                            gigedit will automatically popup on the screen and you're
275                            immediately ready to edit your selected instrument, making all your
276                            modifications audible in realtime. Even when editing huge
277                            instruments of 1GB or more, tweak the instrument with gigedit and
278                            immediately hear it while playing on the keyboard at the same time.
279                            And the good thing: even with new sampler formats we're going to
280                            add soon (and with it new editors), you don't have to remember
281                            which instrument you loaded uses which format. Simply click on
282                            "Edit" in a frontend and the sampler engine will choose the right
283                            instrument editor application for the respective instrument for
284                            you.
285                            </p>
286    
287                            <h2>The Technical Interface</h2>
288                            <p class="default">
289                            As the components of the sampler are independent applications,
290                            there must be a way to let the applications communicate with each
291                            other. For this LinuxSampler provides a native C++
292                            <a href="http://en.wikipedia.org/wiki/Application_programming_interface">API</a>
293                            as well as a network interface using an ASCII based protocol which
294                            we call "<a href="http://www.linuxsampler.org/api/draft-linuxsampler-protocol.html" title="LinuxSampler Control Protocol">LSCP</a>"
295                            for controlling the sampler engine and managing sampler sessions.
296                            Our frontends support that network interface, which also allows to
297                            control the sampler engine with the GUI frontend(s) remotely from
298                            another computer, probably even running a completely different
299                            Operating System. And compared to other remote control solutions,
300                            the frontend won't feel sluggish, as the frontend is running on
301                            your local machine.<br>
302                            <br>
303                            You can also configure your computer to automatically start the
304                            sampler engine and loading your prefered sampler session without
305                            any frontend, simply by using a <i>LSCP session file</i>. How do
306                            you get such a "LSCP session file"? Both frontends write LSCP
307                            session files for you when you request them to save your current
308                            sampler session. And as those LSCP session files are ordinary
309                            human readable text files, you can adjust them with any text
310                            editor if you want.
311                            </p>
312    
313                            <h2>The Compatibility</h2>
314                            <p class="default">
315                            LinuxSampler is available for the most popular operating
316                            systems and already supports a variety of audio and MIDI driver
317                            systems on each OS. It does not require any special dedicated
318                            device drivers from the sound card manufacturers, so you can
319                            also use it with cheap consumer cards. Due to its clean design
320                            the sampler can be ported to other operating systems and
321                            extended for further driver systems with a minimum of effort.
322                            So we're prepared for the future!

333                          using an ASCII based protocol called <a href="http://www.linuxsampler.org/api/draft-linuxsampler-protocol.html">LSCP</a>                          documentation, providing artwork, themes for frontends, etc. helps
334                          for controlling the sampler and managing sampler sessions. But don't be afraid, with QSampler (based on the                          us and all users a lot! Simply subscribe to our
335                          cross-platform C++ GUI library Qt) and JSampler (Java based, thus platform independent) we already have two convenient                          <a href="http://lists.sourceforge.net/lists/listinfo/linuxsampler-devel">
336                          frontends for LinuxSampler and due to the                                  mailing list
337                          decoupled design you can even control the sampler with the GUI frontend(s) from another computer, probably even running                          </a> and we'll of course take you by the hand in case you want to
338                          another OS like Windows or OS X. Beside our own custom network control layer we planned to add existing ones as well                          participate with active source code development. Don't be afraid!
339                          (e.g. <a href="http://www.cnmat.berkeley.edu/OpenSoundControl/">OSC</a>). With the planned SMP and cluster support                          You have your own ideas and concepts for making the sampler better?
340                          LinuxSampler might become a very interesting tool for high-end studios and concerts in future.<br>                          Great, share them with us!<br>
                         <br>  
                         It is planned to support all common sampler formats in LinuxSampler, but at the moment we chose to concentrate on the  
                         Gigasampler format, because we think it's currently the best sampler format in regards of quality and power, especially  
                         for the synthesis of natural instruments like pianos, brass and bowed instruments. But we already made good advance in  
                         implementing this format, so we are optimistic to start with adding other formats soon. Beside that we also planned to  
                         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>  
341                          <br>                          <br>
                         Anyway, there are so many things to do and our hands are limited. So don't hesitate on participating to the project!
