260 <h2>LSCP Reference</h2>
261 <p class="default">
262 The following documents define the <i>LinuxSampler Control Protocol</i>,
263 a network protocol with which LinuxSampler can be controlled locally as well as remotely.
264 As this is a simple ASCII based protocol it's possible to write a frontend for LinuxSampler in
265 any programming language and GUI library. There's still a big demand especially for a Gtk and
266 ncurses based frontend, so be encouraged and let
267 <a href="http://www.linuxsampler.org/developers.html">us</a> know if you wrote a frontend for
268 LinuxSampler!

359 The protocol will be extended from time to time. You may look at the
360 <a href="features.html#LSCP">features</a> site to see which control
361 commands are already implemented and which are not.
362 </p>

365 <a name="example_lscp_scripts">
366 <h3>Example LSCP scripts</h3>
367 <p class="default">
368 If you don't want / can't use a GUI frontend you will probably write some LSCP scripts for
369 using with linuxsampler to setup your needed sampler session. It follows some common LSCP
370 examples to give you a good starting point for writing your own ones. Adjust it to your needs
371 and send it to the running linuxsampler application with:
372 </p>
373 <pre class="code">cat yourscript.lscp | netcat localhost 8888</pre>
374 <p class="default">
375 Optionally you can also use a graphical frontend like QSampler one time to setup a working
376 sampler session for your needs and save it. Because you have to know that the files saved
377 by our frontends are actually pure LSCP scripts, thus you can i.e. use those files simply with
378 the mentioned netcat command from above to setup the sampler session without a frontend.
379 </p>
380 <p class="default">
381 Here is a simple LSCP example which uses ALSA as MIDI input and as audio output driver as well,
382 it creates only one sampler channel using the Gigasampler engine and loads a Piano instrument
383 on that sampler channel:
384 </p>
385 <pre class="code">#enable echo mode
386 SET ECHO 1
387
388 # load the ALSA audio driver
389 # (parameter CARD is optional, I use it here to select my 2nd sound card
390 # you can use 'GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO ALSA CARD' to get
391 # all available sound cards)
392 CREATE AUDIO_OUTPUT_DEVICE ALSA CARD='1,0'
393
394 # load the ALSA MIDI driver
395 CREATE MIDI_INPUT_DEVICE ALSA
396
397 # connect my MIDI keyboard which has ALSA seq ID '72:0'
398 # (see 'aconnect -i' for the IDs of your MIDI devices
399 # or use 'GET MIDI_INPUT_PORT_PARAMETER INFO 0 0 ALSA_SEQ_BINDINGS')
400 SET MIDI_INPUT_PORT_PARAMETER 0 0 ALSA_SEQ_BINDINGS='72:0'
401
402 # setup a sampler channel
403 ADD CHANNEL
404 LOAD ENGINE gig 0
405 SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0
406 SET CHANNEL MIDI_INPUT_DEVICE 0 0
407 LOAD INSTRUMENT '/home/me/Gigs/PMI Steinway D.gig' 0 0
408
409 # finally show our channel setup (optional of course)
410 GET CHANNEL INFO 0
411
412 # quit connection
413 QUIT</pre>
414 <p class="default">
415 The next example uses JACK as audio output driver instead and automatically connects the two
416 output channels of LS's JACK client to the first two ALSA PCM channels, so you can hear
417 something without having to manually connect it e.g. with qjackctl:
418 </p>
419 <pre class="code">#enable echo mode
420 SET ECHO 1
421
422 # load the JACK audio driver
423 CREATE AUDIO_OUTPUT_DEVICE JACK
424
425 # connect to ALSA playback JACK client so we can hear something
426 # (you can use 'GET AUDIO_OUTPUT_CHANNEL_PARAMETER INFO 0 0 JACK_BINDINGS'
427 # to get all available JACK clients / ports)
428 SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 JACK_BINDINGS='alsa_pcm:playback_1'
429 SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 1 JACK_BINDINGS='alsa_pcm:playback_2'
430
431 # load the ALSA MIDI driver
432 CREATE MIDI_INPUT_DEVICE ALSA
433
434 # connect my MIDI keyboard which has ALSA seq ID '72:0'
435 # (see 'aconnect -i' for the IDs of your MIDI devices
436 # or use 'GET MIDI_INPUT_PORT_PARAMETER INFO 0 0 ALSA_SEQ_BINDINGS')
437 SET MIDI_INPUT_PORT_PARAMETER 0 0 ALSA_SEQ_BINDINGS='72:0'
438
439 # setup one sampler channel
440 ADD CHANNEL
441 LOAD ENGINE gig 0
442 SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0
443 SET CHANNEL MIDI_INPUT_DEVICE 0 0
444 LOAD INSTRUMENT '/home/me/Gigs/PMI Steinway D.gig' 0 0
445
446 # finally show our channel setup (optional of course)
447 GET CHANNEL INFO 0
448
449 # quit connection
450 QUIT</pre>
451 <p class="default">
452 The next example is a bit more complex.
453 It shows how to setup a more realistic sampler session, handle routing of MIDI input channels,
454 handle routing of audio channels, it uses JACK again as audio
455 output driver, but creates the JACK client with four output channels instead, it creates two
456 sampler channels, loads two different instrument on those two sampler channels and alters
457 the audio channel routing so that the two output channels of sampler channel 1 are routed to
458 the first two JACK output channels and the two output channels of sampler channel 2 are routed
459 the second pair of the JACK client's output channels. That way you could e.g. record the output
460 of those two sampler channels independently or apply independent LADSPA effects on it.
