<h3>Abstract</h3> |
147 |
|
|
|
148 |
|
|
<p>The LinuxSampler Control Protocol (LSCP) is an |
149 |
|
|
application-level protocol primarily intended for local and |
150 |
|
|
remote controlling the LinuxSampler main application, which is a |
151 |
|
|
sophisticated console application essentially playing back audio |
152 |
|
|
samples and manipulating the samples in real time to certain |
153 |
|
|
extent. |

399 |
|
|
|
400 |
|
|
<p>LinuxSampler is a so called software sampler application |
401 |
|
|
capable to playback audio samples from a computer's Random |
402 |
|
|
Access Memory (RAM) as well as directly streaming it from disk. |
403 |
|
|
LinuxSampler is designed to be modular. It provides several so |
404 |
|
|
called "sampler engines" where each engine is specialized for a |
405 |
|
|
certain purpose. LinuxSampler has virtual channels which will be |
406 |
|
|
referred in this document as "sampler channels". The channels |
407 |
|
|
are in such way virtual as they can be connected to an |
408 |
|
|
arbitrary MIDI input method and arbitrary MIDI channel (e.g. |
409 |
|
|
sampler channel 17 could be connected to an ALSA sequencer |
410 |
|
|
device 64:0 and listening to MIDI channel 1 there). Each sampler |
411 |
|
|
engine will be assigned an own instance of one of the available |
412 |
|
|
sampler engines (e.g. GigEngine, DLSEngine). The audio output of |
413 |
|
|
each sampler channel can be routed to an arbitrary audio output |
414 |
|
|
method (ALSA / JACK) and an arbitrary audio output channel |
415 |
|
|
there. |

420 |
|
|
|
421 |
|
|
<p>Main focus of this protocol is to provide a way to configure |
422 |
|
|
a running LinuxSampler instance and to retrieve information |
423 |
|
|
about it. The focus of this protocol is not to provide a way to |
424 |
|
|
control synthesis parameters or even to trigger or release |
425 |
|
|
notes. Or in other words; the focus are those functionalities |
426 |
|
|
which are not covered by MIDI or which may at most be handled |
427 |
|
|
via MIDI System Exclusive Messages. |

432 |
|
|
|
433 |
|
|
<p>There are two distinct methods of communication between a |
434 |
|
|
running instance of LinuxSampler and one or more control |
435 |
|
|
applications, so called "front-ends": a simple request/response |
436 |
|
|
communication method used by the clients to give commands to the |
437 |
|
|
server as well as to inquire about server's status and a |
438 |
|
|
subscribe/notify communication method used by the client to |
439 |
|
|
subscribe to and receive notifications of certain events as they |
440 |
|
|
happen on the server. The latter needs more effort to be |
441 |
|
|
implemented in the front-end application. The two communication |
442 |
|
|
methods will be described next. |
443 |
|
|
</p> |
444 |
|
|
<a name="rfc.section.4.1"></a><h4><a name="anchor5">4.1</a> Request/response communication method</h4> |
445 |
|
|
|
446 |
|
|
<p>This simple communication method is based on TCP. The |
447 |
|
|
front-end application establishes a TCP connection to the |
448 |
|
|
LinuxSampler instance on a certain host system. Then the |
449 |
|
|
front-end application will send certain ASCII based commands |
450 |
|
|
as defined in this document (every command line must be CRLF |
451 |
|
|
terminated - see "Conventions used in this document" at the |
452 |
|
|
beginning of this document) and the LinuxSampler application |
453 |
|
|
will response after a certain process time with an |
454 |
|
|
appropriate ASCII based answer, also as defined in this |
455 |
|
|
document. So this TCP communication is simply based on query |
456 |
|
|
and answer paradigm. That way LinuxSampler is only able to |
457 |
|
|
answer on queries from front-ends, but not able to |
458 |
|
|
automatically send messages to the client if it's not asked |
459 |
|
|
to. The fronted should not reconnect to LinuxSampler for |
460 |
|
|
every single command, instead it should keep the connection |
461 |
|
|
established and simply resend message(s) for subsequent |
462 |
|
|
commands. To keep information in the front-end up-to-date |
463 |
|
|
the front-end has to periodically send new requests to get |
464 |
|
|
the current information from the LinuxSampler instance. This |
465 |
|
|
is often referred to as "polling". While polling is simple |
466 |
|
|
to implement and may be OK to use in some cases, there may |
467 |
|
|
be disadvantages to polling such as network traffic overhead |
468 |
|
|
and information being out of date. |
469 |
|
|
It is possible for a client or several clients to open more |
470 |
|
|
than one connection to the server at the same time. It is |
471 |
|
|
also possible to send more than one request to the server |
472 |
|
|
at the same time but if those requests are sent over the |
473 |
|
|
same connection server MUST execute them sequentially. Upon |
474 |
|
|
executing a request server will produce a result set and |
475 |
|
|
send it to the client. Each and every request made by the |
476 |
|
|
client MUST result in a result set being sent back to the |
477 |
|
|
client. No other data other than a result set may be sent by |
478 |
|
|
a server to a client. No result set may be sent to a client |
479 |
|
|
without the client sending request to the server first. On |
480 |
|
|
any particular connection, result sets MUST be sent in their |
481 |
|
|
entirety without being interrupted by other result sets. If |
482 |
|
|
several requests got queued up at the server they MUST be |
483 |
|
|
processed in the order they were received and result sets |
484 |
|
|
MUST be sent back in the same order. |

|
<p>Clients may choose to open more than one connection to |

|
|
the server and use some connections to receive notifications |
739 |
|
|
while using other connections to issue commands to the |
740 |
|
|
back-end. This is entirely legal and up to the |
741 |
|
|
implementation. This does not change the protocol in any way |
742 |
|
|
and no special restrictions exist on the server to allow or |
743 |
|
|
disallow this or to track what connections belong to what |
744 |
|
|
front-ends. Server will listen on a single port, accept |
745 |

multiple connections and support protocol described in this |
746 |

<p>Due to the fact that TCP is used for this communication, |

dead peers will be detected automatically by the OS TCP |

752 |

traffic is being sent from server to client (TCP keep-alive |
753 |
|
|
timer is set to 2 hours on many OSes) it will not be an |
754 |
|

issue here as when notifications are sent by the server, |
755 |
|

dead client will be detected quickly. |
756 |

757 |

|
<p>When connection is closed for any reason server MUST |

<a name="rfc.section.5.2"></a><h4><a name="anchor10">5.2</a> Configuring audio drivers</h4> |
782 |
|
|
|
783 |
|
|
<p>Instances of drivers in LinuxSampler are called devices. |
784 |
|
|
You can use multiple audio devices simultaneously, e.g. to |
785 |
|
|
output the sound of one sampler channel using the ALSA audio |
786 |
|
|
output driver, and on another sampler channel you might want |
787 |
|
|
to use the JACK audio output driver. For particular audio |
788 |
|
|
output systems it's also possible to create several devices |
789 |
|
|
of the same audio output driver, e.g. two separate ALSA |
790 |
|
|
audio output devices for using two different sound cards at |
791 |
|
|
the same time. This chapter describes all commands to |
792 |
|
|
configure LinuxSampler's audio output devices and their |
793 |
|
|
parameters. |
794 |
|
|
</p> |
795 |
|
|
<p>Instead of defining commands and parameters for each |
796 |
|
|
driver individually, all possible parameters, their meanings |
797 |
|
|
and possible values have to be obtained at runtime. This |
798 |
|
|
makes the protocol a bit abstract, but has the advantage, |
799 |
|
|
that front-ends can be written independently of what drivers |
800 |
|
|
are currently implemented and what parameters these drivers |
801 |
|
|
are actually offering. This means front-ends can even handle |
802 |
|
|
drivers which are implemented somewhere in future without |
803 |
|
|
modifying the front-end at all. |
804 |
|
|
</p> |
805 |
|
|
<p>Note: examples in this chapter showing particular |
806 |
|
|
parameters of drivers are not meant as specification of the |
807 |
|
|
drivers' parameters. Driver implementations in LinuxSampler |
808 |
|
|
might have complete different parameter names and meanings |
809 |
|
|
than shown in these examples or might change in future, so |
810 |
|
|
these examples are only meant for showing how to retrieve |
811 |
|
|
what parameters drivers are offering, how to retrieve their |
812 |
|
|
possible values, etc. |

<a name="rfc.section.5.3"></a><h4><a name="anchor11">5.3</a> Configuring MIDI input drivers</h4> |
1838 |
|
|
|
1839 |
|
|
<p>Instances of drivers in LinuxSampler are called devices. You can use |
1840 |
|
|
multiple MIDI devices simultaneously, e.g. to use MIDI over ethernet as |
1841 |
|
|
MIDI input on one sampler channel and ALSA as MIDI input on another sampler |
1842 |
|
|
channel. For particular MIDI input systems it's also possible to create |
1843 |
|
|
several devices of the same MIDI input type. This chapter describes all |
1844 |
|
|
commands to configure LinuxSampler's MIDI input devices and their parameters. |
1845 |
|
|
</p> |
1846 |
|
|
<p>Instead of defining commands and parameters for each driver individually, |
1847 |
|
|
all possible parameters, their meanings and possible values have to be obtained |
1848 |
|
|
at runtime. This makes the protocol a bit abstract, but has the advantage, that |
1849 |
|
|
front-ends can be written independently of what drivers are currently implemented |
1850 |
|
|
and what parameters these drivers are actually offering. This means front-ends can |
1851 |
|
|
even handle drivers which are implemented somewhere in future without modifying |
1852 |
|
|
the front-end at all. |
1853 |
|
|
</p> |
1854 |
|
|
<p>Commands for configuring MIDI input devices are pretty much the same as the |
1855 |
|
|
commands for configuring audio output drivers, already described in the last |
1856 |
|
|
chapter. |
1857 |
|
|
</p> |
1858 |
|
|
<p>Note: examples in this chapter showing particular parameters of drivers are |
1859 |
|
|
not meant as specification of the drivers' parameters. Driver implementations in |
1860 |
|
|
LinuxSampler might have complete different parameter names and meanings than shown |
1861 |
|
|
in these examples or might change in future, so these examples are only meant for |
1862 |
|
|
showing how to retrieve what parameters drivers are offering, how to retrieve their |
1863 |
|
|
possible values, etc. |
