<h3>Abstract</h3> |
| 183 |
|
| 184 |
<p>The LinuxSampler Control Protocol (LSCP) is an |
| 185 |
application-level protocol primarily intended for local and |
| 186 |
remote controlling the LinuxSampler backend application, which is a |
| 187 |
sophisticated server-like console application essentially playing |
| 188 |
back audio samples and manipulating the samples in real time to |
| 189 |
certain extent. |

<p>The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", |
| 422 |
"SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", |
| 423 |
and "OPTIONAL" in this document are to be interpreted as |
| 424 |
described in <a class='info' href='#RFC2119'>[RFC2119]<span> (</span><span class='info'>Bradner, S., “Key words for use in RFCs to Indicate Requirement Levels,” 1997.</span><span>)</span></a>. |

</p> |
| 426 |
<p>This protocol is always case-sensitive if not explicitly |
| 427 |
claimed the opposite. |
| 428 |
</p> |
| 429 |
<p>In examples, "C:" and "S:" indicate lines sent by the client |
| 430 |
(front-end) and server (LinuxSampler) respectively. Lines in |
| 431 |
examples must be interpreted as every line being CRLF |
| 432 |
terminated (carriage return character followed by line feed |
| 433 |
character as defined in the ASCII standard), thus the following |
| 434 |
example: |
| 435 |
</p> |
| 436 |
<p> |
| 437 |
</p> |
| 438 |
<blockquote class="text"> |
| 439 |
<p>C: "some line" |
| 440 |
</p> |
| 441 |
<p> "another line" |
| 442 |
</p> |
| 443 |
</blockquote><p> |
| 444 |
|
| 445 |
</p> |
| 446 |
<p>must actually be interpreted as client sending the following |
| 447 |
message: |
| 448 |
</p> |
| 449 |
<p> |
| 450 |
</p> |
| 451 |
<blockquote class="text"> |
| 452 |
<p>"some line<CR><LF>another |
| 453 |
line<CR><LF>" |
| 454 |
</p> |
| 455 |
</blockquote><p> |
| 456 |
|
| 457 |
</p> |
| 458 |
<p>where <CR> symbolizes the carriage return character and |
| 459 |
<LF> the line feed character as defined in the ASCII |
| 460 |
standard. |
| 461 |
</p> |
| 462 |
<p>Due to technical reasons, messages can arbitrary be |
| 463 |
fragmented, means the following example: |
| 464 |
</p> |
| 465 |
<p> |
| 466 |
</p> |
| 467 |
<blockquote class="text"> |
| 468 |

</p> |
| 470 |
</blockquote><p> |
| 471 |
|
| 472 |
</p> |
| 473 |
<p>could also happen to be sent in three messages like in the |
| 474 |
following sequence scenario: |
| 475 |
</p> |
| 476 |
<p> |
| 477 |
</p> |
| 478 |
<ul class="text"> |

| 483 |
</li> |
| 484 |
<li>followed by server sending message |

"bcd<CR>" |
| 486 |
</li> |
| 487 |
<li>again followed by a delay (pause) with arbitrary |
| 488 |

| 489 |
</li> |

Versioning of this specification</h3> |
| 503 |
|
| 504 |
<p>LSCP will certainly be extended and enhanced by-and-by. Each official |
| 505 |
release of the LSCP specification will be tagged with a unique version |
| 506 |
tuple. The version tuple consists at least of a major and minor version |
| 507 |
number like: |
| 508 |
|
| 509 |
</p> |
| 510 |
<p> |
| 511 |
</p> |

<blockquote class="text"> |

</blockquote><p> |
| 516 |
|
| 517 |
</p> |
| 518 |
<p> |
| 519 |
In this example the major version number would be "1" and the minor |
| 520 |
version number would be "2". Note that the version tuple might also |
| 521 |
have more than two elements. The major version number defines a |
| 522 |
group of backward compatible versions. That means a frontend is |
| 523 |
compatible to the connected sampler if and only if the LSCP versions |
| 524 |
to which each of the two parties complies to, match both of the |
| 525 |
following rules: |
| 526 |
|
| 527 |
</p> |
| 528 |
<p>Compatibility: |
| 529 |
</p> |
| 530 |
<p> |
| 531 |
</p> |
| 532 |
<ol class="text"> |
| 533 |
<li>The frontend's LSCP major version and the sampler's LSCP |
| 534 |
major version are exactly equal. |
| 535 |
</li> |
| 536 |
<li>The frontend's LSCP minor version is less or equal than |
| 537 |
the sampler's LSCP minor version. |
| 538 |
</li> |
| 539 |
</ol><p> |
| 540 |
|
| 541 |
</p> |
| 542 |
<p> |
| 543 |
Compatibility can only be claimed if both rules are true. |
| 544 |
The frontend can use the |
| 545 |
<a class='info' href='#GET SERVER INFO'>"GET SERVER INFO"<span> (</span><span class='info'>General sampler informations</span><span>)</span></a> command to |
| 546 |
get the version of the LSCP specification the sampler complies with. |

Introduction</h3> |
| 553 |
|
| 554 |
<p>LinuxSampler is a so called software sampler application |
| 555 |
capable to playback audio samples from a computer's Random |
| 556 |
Access Memory (RAM) as well as directly streaming it from disk. |
| 557 |
LinuxSampler is designed to be modular. It provides several so |
| 558 |
called "sampler engines" where each engine is specialized for a |
| 559 |
certain purpose. LinuxSampler has virtual channels which will be |
| 560 |
referred in this document as "sampler channels". The channels |
| 561 |
are in such way virtual as they can be connected to an |
| 562 |
arbitrary MIDI input method and arbitrary MIDI channel (e.g. |
| 563 |
sampler channel 17 could be connected to an ALSA sequencer |
| 564 |
device 64:0 and listening to MIDI channel 1 there). Each sampler |
| 565 |
channel will be associated with an instance of one of the available |
| 566 |
sampler engines (e.g. GigEngine, DLSEngine). The audio output of |
| 567 |
each sampler channel can be routed to an arbitrary audio output |
| 568 |
method (ALSA / JACK) and an arbitrary audio output channel |
| 569 |
there. |

Communication Overview</h3> |
| 588 |
|
| 589 |
<p>There are two distinct methods of communication between a |
| 590 |
running instance of LinuxSampler and one or more control |
| 591 |
applications, so called "front-ends": a simple request/response |
| 592 |
communication method used by the clients to give commands to the |
| 593 |
server as well as to inquire about server's status and a |
| 594 |
subscribe/notify communication method used by the client to |
| 595 |
subscribe to and receive notifications of certain events as they |
| 596 |
happen on the server. The latter needs more effort to be |
| 597 |
implemented in the front-end application. The two communication |
| 598 |
methods will be described next. |
| 599 |
</p> |
| 600 |
<a name="anchor5"></a><br /><hr /> |
| 601 |
<table summary="layout" cellpadding="0" cellspacing="2" class="TOCbug" align="right"><tr><td class="TOCbug"><a href="#toc"> TOC </a></td></tr></table> |
| 602 |
<a name="rfc.section.5.1"></a><h3>5.1. |
| 603 |
Request/response communication method</h3> |
| 604 |
|
| 605 |
<p>This simple communication method is based on |
| 606 |
<a class='info' href='#RFC793'>TCP<span> (</span><span class='info'>Defense Advanced Research Projects Agency, “TRANSMISSION CONTROL PROTOCOL,” 1981.</span><span>)</span></a> [RFC793]. The |
| 607 |
front-end application establishes a TCP connection to the |
| 608 |
LinuxSampler instance on a certain host system. Then the |
| 609 |
front-end application will send certain ASCII based commands |
| 610 |
as defined in this document (every command line must be CRLF |
| 611 |
terminated - see "Conventions used in this document" at the |
| 612 |
beginning of this document) and the LinuxSampler application |
| 613 |
will response after a certain process time with an |
| 614 |
appropriate ASCII based answer, also as defined in this |
| 615 |
document. So this TCP communication is simply based on query |
| 616 |
and answer paradigm. That way LinuxSampler is only able to |
| 617 |
answer on queries from front-ends, but not able to |
| 618 |
automatically send messages to the client if it's not asked |
| 619 |
to. The fronted should not reconnect to LinuxSampler for |
| 620 |
every single command, instead it should keep the connection |
| 621 |
established and simply resend message(s) for subsequent |
| 622 |
commands. To keep information in the front-end up-to-date |
| 623 |
the front-end has to periodically send new requests to get |
| 624 |
the current information from the LinuxSampler instance. This |
| 625 |
is often referred to as "polling". While polling is simple |
| 626 |
to implement and may be OK to use in some cases, there may |
| 627 |
be disadvantages to polling such as network traffic overhead |
| 628 |
and information being out of date. |
| 629 |
It is possible for a client or several clients to open more |
| 630 |
than one connection to the server at the same time. It is |
| 631 |
also possible to send more than one request to the server |
| 632 |
at the same time but if those requests are sent over the |
| 633 |
same connection server MUST execute them sequentially. Upon |
| 634 |
executing a request server will produce a result set and |
| 635 |
send it to the client. Each and every request made by the |
| 636 |
client MUST result in a result set being sent back to the |
| 637 |
client. No other data other than a result set may be sent by |
| 638 |
a server to a client. No result set may be sent to a client |
| 639 |
without the client sending request to the server first. On |
| 640 |
any particular connection, result sets MUST be sent in their |
| 641 |
entirety without being interrupted by other result sets. If |
| 642 |
several requests got queued up at the server they MUST be |
| 643 |
processed in the order they were received and result sets |
| 644 |
MUST be sent back in the same order. |

Subscribe/notify communication method</h3> |
| 843 |
|
| 844 |
<p>This more sophisticated communication method is actually |
| 845 |
only an extension of the simple request/response |
| 846 |
communication method. The front-end still uses a TCP |
| 847 |
connection and sends the same commands on the TCP |
| 848 |
connection. Two extra commands are SUBSCRIBE and UNSUBSCRIBE |
| 849 |
commands that allow a client to tell the server that it is |
| 850 |
interested in receiving notifications about certain events |
| 851 |
as they happen on the server. The SUBSCRIBE command has the |
| 852 |
following syntax: |
| 853 |
</p> |
| 854 |
<p> |
| 855 |
</p> |
| 856 |
<blockquote class="text"> |
| 857 |
<p>SUBSCRIBE <event-id> |
| 858 |
</p> |
| 859 |
</blockquote><p> |
| 860 |
|
| 861 |
</p> |
| 862 |
<p>where <event-id> will be replaced by the respective |
| 863 |
event that client wants to subscribe to. Upon receiving such |
| 864 |
request, server SHOULD respond with OK and start sending |
| 865 |
EVENT notifications when a given even has occurred to the |
| 866 |
front-end when an event has occurred. It MAY be possible |
| 867 |
certain events may be sent before OK response during real |
| 868 |
time nature of their generation. Event messages have the |
| 869 |
following format: |
| 870 |
</p> |
| 871 |
<p> |
| 872 |
</p> |
| 873 |
<blockquote class="text"> |
| 874 |
<p>NOTIFY:<event-id>:<custom-event-data> |
| 875 |
</p> |
| 876 |
</blockquote><p> |
| 877 |
|
| 878 |
</p> |
| 879 |
<p>where <event-id> uniquely identifies the event that |
| 880 |
has occurred and <custom-event-data> is event |
| 881 |
specific. |
| 882 |
</p> |
| 883 |
<p>Several rules must be followed by the server when |
| 884 |
generating events: |
| 885 |
</p> |
| 886 |
<p> |
| 887 |
</p> |
| 888 |
<ol class="text"> |
| 889 |
<li>Events MUST NOT be sent to any client who has not |
| 890 |
issued an appropriate SUBSCRIBE command. |
| 891 |
</li> |
| 892 |
<li>Events MUST only be sent using the same |
| 893 |
connection that was used to subscribe to them. |
| 894 |
</li> |
| 895 |
<li>When response is being sent to the client, event |
| 896 |
MUST be inserted in the stream before or after the |
| 897 |
response, but NOT in the middle. Same is true about |
| 898 |
the response. It should never be inserted in the |
| 899 |
middle of the event message as well as any other |
| 900 |
response. |
| 901 |
</li> |
| 902 |
</ol><p> |
| 903 |
|
| 904 |
</p> |
| 905 |
<p>If the client is not interested in a particular event |
| 906 |
anymore it MAY issue UNSUBSCRIBE command using the following |
| 907 |
syntax: |
| 908 |
</p> |
| 909 |
<p> |
| 910 |
</p> |
| 911 |
<blockquote class="text"> |
| 912 |
<p>UNSUBSCRIBE <event-id> |
| 913 |
</p> |
| 914 |
</blockquote><p> |
| 915 |
|
| 916 |
</p> |
| 917 |
<p>where <event-id> will be replace by the respective |
| 918 |
event that client is no longer interested in receiving. For |
| 919 |
a list of supported events see <a class='info' href='#events'>Section 8<span> (</span><span class='info'>Events</span><span>)</span></a>. |
| 920 |
</p> |
| 921 |
<p>Example: the fill states of disk stream buffers have |
| 922 |
changed on sampler channel 4 and the LinuxSampler instance |
| 923 |
will react by sending the following message to all clients |
| 924 |
who subscribed to this event: |
| 925 |
</p> |
| 926 |
<p> |
| 927 |
</p> |
| 928 |
<blockquote class="text"> |
| 929 |
<p>NOTIFY:CHANNEL_BUFFER_FILL:4 [35]62%,[33]80%,[37]98% |
| 930 |
</p> |
| 931 |
</blockquote><p> |
| 932 |
|
| 933 |
</p> |
| 934 |
<p>Which means there are currently three active streams on |
| 935 |
sampler channel 4, where the stream with ID "35" is filled |
| 936 |
by 62%, stream with ID 33 is filled by 80% and stream with |
| 937 |
ID 37 is filled by 98%. |
| 938 |
</p> |
| 939 |
<p>Clients may choose to open more than one connection to |
| 940 |
the server and use some connections to receive notifications |
| 941 |
while using other connections to issue commands to the |
| 942 |
back-end. This is entirely legal and up to the |
| 943 |
implementation. This does not change the protocol in any way |
| 944 |
and no special restrictions exist on the server to allow or |
| 945 |
disallow this or to track what connections belong to what |
| 946 |
front-ends. Server will listen on a single port, accept |
| 947 |
multiple connections and support protocol described in this |
| 948 |
specification in it's entirety on this single port on each |
| 949 |
connection that it accepted. |
| 950 |
</p> |
| 951 |
<p>Due to the fact that TCP is used for this communication, |
| 952 |
dead peers will be detected automatically by the OS TCP |
| 953 |
stack. While it may take a while to detect dead peers if no |
| 954 |
traffic is being sent from server to client (TCP keep-alive |
| 955 |
timer is set to 2 hours on many OSes) it will not be an |
| 956 |
issue here as when notifications are sent by the server, |
| 957 |
dead client will be detected quickly. |
| 958 |
</p> |
| 959 |
<p>When connection is closed for any reason server MUST |
| 960 |
forget all subscriptions that were made on this connection. |
| 961 |
If client reconnects it MUST resubscribe to all events that |
| 962 |
it wants to receive. |

| 990 |
Configuring audio drivers</h3> |
| 991 |
|
| 992 |
<p>Instances of drivers in LinuxSampler are called devices. |
| 993 |
You can use multiple audio devices simultaneously, e.g. to |
| 994 |
output the sound of one sampler channel using the ALSA audio |
| 995 |
output driver, and on another sampler channel you might want |
| 996 |
to use the JACK audio output driver. For particular audio |
| 997 |
output systems it's also possible to create several devices |
| 998 |
of the same audio output driver, e.g. two separate ALSA |
| 999 |
audio output devices for using two different sound cards at |
| 1000 |
the same time. This chapter describes all commands to |
| 1001 |
configure LinuxSampler's audio output devices and their |
| 1002 |
parameters. |
| 1003 |
</p> |
| 1004 |
<p>Instead of defining commands and parameters for each |
| 1005 |
driver individually, all possible parameters, their meanings |
| 1006 |
and possible values have to be obtained at runtime. This |
| 1007 |
makes the protocol a bit abstract, but has the advantage, |
| 1008 |
that front-ends can be written independently of what drivers |
| 1009 |
are currently implemented and what parameters these drivers |
| 1010 |
are actually offering. This means front-ends can even handle |
| 1011 |
drivers which are implemented somewhere in future without |
| 1012 |
modifying the front-end at all. |
| 1013 |
</p> |
| 1014 |
<p>Note: examples in this chapter showing particular |
| 1015 |
parameters of drivers are not meant as specification of the |
| 1016 |
drivers' parameters. Driver implementations in LinuxSampler |
| 1017 |
might have complete different parameter names and meanings |
| 1018 |
than shown in these examples or might change in future, so |
| 1019 |
these examples are only meant for showing how to retrieve |
| 1020 |
what parameters drivers are offering, how to retrieve their |
| 1021 |
possible values, etc. |

Configuring MIDI input drivers</h3> |
| 2238 |
|
| 2239 |
<p>Instances of drivers in LinuxSampler are called devices. You can use |
| 2240 |
multiple MIDI devices simultaneously, e.g. to use MIDI over ethernet as |
| 2241 |
MIDI input on one sampler channel and ALSA as MIDI input on another sampler |
| 2242 |
channel. For particular MIDI input systems it's also possible to create |
| 2243 |
several devices of the same MIDI input type. This chapter describes all |
| 2244 |
commands to configure LinuxSampler's MIDI input devices and their parameters. |
| 2245 |
</p> |
| 2246 |
<p>Instead of defining commands and parameters for each driver individually, |
| 2247 |
all possible parameters, their meanings and possible values have to be obtained |
| 2248 |
at runtime. This makes the protocol a bit abstract, but has the advantage, that |
| 2249 |
front-ends can be written independently of what drivers are currently implemented |
| 2250 |
and what parameters these drivers are actually offering. This means front-ends can |
| 2251 |
even handle drivers which are implemented somewhere in future without modifying |
| 2252 |
the front-end at all. |
| 2253 |
</p> |
| 2254 |
<p>Commands for configuring MIDI input devices are pretty much the same as the |
| 2255 |
commands for configuring audio output drivers, already described in the last |
| 2256 |
chapter. |
| 2257 |
</p> |
| 2258 |
<p>Note: examples in this chapter showing particular parameters of drivers are |
| 2259 |
not meant as specification of the drivers' parameters. Driver implementations in |
| 2260 |
LinuxSampler might have complete different parameter names and meanings than shown |
| 2261 |
in these examples or might change in future, so these examples are only meant for |
| 2262 |
showing how to retrieve what parameters drivers are offering, how to retrieve their |
| 2263 |
possible values, etc. |

| 3278 |
Loading an instrument</h3> |
| 3279 |
|
| 3280 |
<p>An instrument file can be loaded and assigned to a sampler channel by one of the following commands: |
| 3281 |
</p> |
| 3282 |
<p> |
| 3283 |
</p> |
| 3284 |
<blockquote class="text"> |
| 3285 |
<p>LOAD INSTRUMENT [NON_MODAL] '<filename>' <instr-index> <sampler-channel> |
| 3286 |
</p> |
| 3287 |
</blockquote><p> |
| 3288 |
|
| 3289 |
</p> |
| 3290 |
<p>Where <filename> is the name of the instrument file on the |
| 3291 |
LinuxSampler instance's host system, <instr-index> the index of the |
| 3292 |
instrument in the instrument file and <sampler-channel> is the |
| 3293 |
number of the sampler channel the instrument should be assigned to. |
| 3294 |
Each sampler channel can only have one instrument. |
| 3295 |
</p> |
| 3296 |
<p>The difference between regular and NON_MODAL versions of the command |
| 3297 |
is that the regular command returns OK only after the instrument has been |
| 3298 |
fully loaded and the channel is ready to be used while NON_MODAL version |
| 3299 |
returns immediately and a background process is launched to load the instrument |
| 3300 |
on the channel. The <a class='info' href='#GET CHANNEL INFO'>GET CHANNEL INFO<span> (</span><span class='info'>Getting sampler channel information</span><span>)</span></a> |
| 3301 |
command can be used to obtain loading |
| 3302 |
progress from INSTRUMENT_STATUS field. LOAD command will perform sanity checks |
| 3303 |
such as making sure that the file could be read and it is of a proper format |
| 3304 |
and SHOULD return ERR and SHOULD not launch the background process should any |
| 3305 |
errors be detected at that point. |

MIDI Instrument Mapping</h3> |
| 5399 |
|
| 5400 |
<p>The MIDI protocol provides a way to switch between instruments |
| 5401 |
by sending so called MIDI bank select and MIDI program change |
| 5402 |
messages which are essentially just numbers. The following commands |
| 5403 |
allow to actually map arbitrary MIDI bank select / program change |
| 5404 |
numbers with real instruments. |
| 5405 |
</p> |
| 5406 |
<p>The sampler allows to manage an arbitrary amount of MIDI |
| 5407 |
instrument maps which define which instrument to load on |
| 5408 |
which MIDI program change message. |
| 5409 |
</p> |
| 5410 |
<p>By default, that is when the sampler is launched, there is no |
| 5411 |
map, thus the sampler will simply ignore all program change |
| 5412 |
messages. The front-end has to explicitly create at least one |
| 5413 |
map, add entries to the map and tell the respective sampler |
| 5414 |
channel(s) which MIDI instrument map to use, so the sampler |
| 5415 |
knows how to react on a given program change message on the |
| 5416 |
respective sampler channel, that is by switching to the |
| 5417 |
respectively defined engine type and loading the respective |
| 5418 |
instrument. See command |
| 5419 |
<a class='info' href='#SET CHANNEL MIDI_INSTRUMENT_MAP'>"SET CHANNEL MIDI_INSTRUMENT_MAP"<span> (</span><span class='info'>Assigning a MIDI instrument map to a sampler channel</span><span>)</span></a> |
| 5420 |
for how to assign a MIDI instrument map to a sampler channel. |
| 5421 |
</p> |
| 5422 |
<p>Also note per MIDI specification a bank select message does not |
| 5423 |
cause to switch to another instrument. Instead when receiving a |
| 5424 |

The <instr_load_mode> argument thus allows to define an |
| 5897 |
appropriate strategy (low memory consumption vs. fast |
| 5898 |
instrument switching) for each instrument individually. Note, the |
| 5899 |
following restrictions apply to this argument: "ON_DEMAND_HOLD" and |
| 5900 |
"PERSISTENT" have to be supported by the respective sampler engine |
| 5901 |
(which is technically the case when the engine provides an |
| 5902 |
InstrumentManager for its format). If this is not the case the |
| 5903 |
argument will automatically fall back to the default value |
| 5904 |
"ON_DEMAND". Also the load mode of one instrument may |
| 5905 |
automatically change the laod mode of other instrument(s), i.e. |
| 5906 |
because the instruments are part of the same file and the |
| 5907 |
engine does not allow a way to manage load modes for them |
| 5908 |
individually. Due to this, in case the frontend shows the |
| 5909 |
load modes of entries, the frontend should retrieve the actual |
| 5910 |
mode by i.e. sending |
| 5911 |
<a class='info' href='#GET MIDI_INSTRUMENT INFO'>"GET MIDI_INSTRUMENT INFO"<span> (</span><span class='info'>Get current settings of MIDI instrument map entry</span><span>)</span></a> |
| 5912 |
command(s). Finally the OPTIONAL <name> argument allows to |
| 5913 |
set a custom name (encapsulated into apostrophes) for the mapping |
| 5914 |
entry, useful for frontends for displaying an appropriate name for |
| 5915 |
mapped instruments (using |
| 5916 |
<a class='info' href='#GET MIDI_INSTRUMENT INFO'>"GET MIDI_INSTRUMENT INFO"<span> (</span><span class='info'>Get current settings of MIDI instrument map entry</span><span>)</span></a>). |

</p> |
| 5919 |
<p> |
| 5920 |
The "MAP MIDI_INSTRUMENT" command |
| 5921 |
will immediately return, thus it will not block when an |
| 5922 |
instrument is to be loaded due to a "PERSISTENT" type |
| 5923 |
entry as instruments are loaded in the background. As a |
| 5924 |
consequence this command may not necessarily return an error |
| 5925 |
i.e. when the given instrument file does not exist or may |
| 5926 |
turn out to be corrupt. |

<p>where <device-id> will be replaced by the numerical ID of the audio output device, |
| 7241 |
which settings has been changed. The front-end will have to send |
| 7242 |
the respective command to actually get the audio output device info. Because these messages |
| 7243 |
will be triggered by LSCP commands issued by other clients rather than real |
| 7244 |
time events happening on the server, it is believed that an empty notification |
| 7245 |
message is sufficient here. |

Security Considerations</h3> |
| 7651 |
|
| 7652 |
<p>As there is so far no method of authentication and authorization |
| 7653 |
defined and so not required for a client applications to succeed to |
| 7654 |
connect, running LinuxSampler might be a security risk for the host |
| 7655 |
system the LinuxSampler instance is running on. |
