<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. |

"SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", |

| 452 |
<p>This protocol is always case-sensitive if not explicitly |
| 453 |
claimed the opposite. |
| 454 |
</p> |
| 455 |
<p>In examples, "C:" and "S:" indicate lines sent by the client |
| 456 |
(front-end) and server (LinuxSampler) respectively. Lines in |
| 457 |
examples must be interpreted as every line being CRLF |
| 458 |
terminated (carriage return character followed by line feed |
| 459 |
character as defined in the ASCII standard), thus the following |
| 460 |
example: |
| 461 |
</p> |
| 462 |
<p> |
| 463 |
</p> |
| 464 |
<blockquote class="text"> |
| 465 |
<p>C: "some line" |
| 466 |
</p> |
| 467 |
<p> "another line" |

</p> |
| 469 |
</blockquote><p> |
| 470 |
|
| 471 |
</p> |
| 472 |
<p>must actually be interpreted as client sending the following |
| 473 |
message: |
| 474 |
</p> |
| 475 |
<p> |
| 476 |
</p> |
| 477 |
<blockquote class="text"> |

</p> |
| 481 |
</blockquote><p> |
| 482 |
|
| 483 |
</p> |
| 484 |
<p>where <CR> symbolizes the carriage return character and |
| 485 |
<LF> the line feed character as defined in the ASCII |
| 486 |
standard. |
| 487 |
</p> |
| 488 |
<p>Due to technical reasons, messages can arbitrary be |
| 489 |
fragmented, means the following example: |
| 490 |
</p> |
| 491 |
<p> |
| 492 |
</p> |
| 493 |
<blockquote class="text"> |

Versioning of this specification</h3> |
| 529 |
|
| 530 |
<p>LSCP will certainly be extended and enhanced by-and-by. Each official |
| 531 |
release of the LSCP specification will be tagged with a unique version |
| 532 |
tuple. The version tuple consists at least of a major and minor version |
| 533 |
number like: |

|

</blockquote><p> |
| 542 |
|
| 543 |
</p> |
| 544 |
<p> |
| 545 |
In this example the major version number would be "1" and the minor |
| 546 |
version number would be "2". Note that the version tuple might also |
| 547 |
have more than two elements. The major version number defines a |
| 548 |
group of backward compatible versions. That means a frontend is |
| 549 |
compatible to the connected sampler if and only if the LSCP versions |
| 550 |
to which each of the two parties complies to, match both of the |
| 551 |
following rules: |
| 552 |
|
| 553 |
</p> |
| 554 |
<p>Compatibility: |

</p> |
| 556 |
<p> |

</p> |
| 558 |
<ol class="text"> |
| 559 |
<li>The frontend's LSCP major version and the sampler's LSCP |
| 560 |
major version are exactly equal. |
| 561 |
</li> |
| 562 |
<li>The frontend's LSCP minor version is less or equal than |

the sampler's LSCP minor version. |

</li> |
| 565 |
</ol><p> |
| 566 |
|
| 567 |
</p> |
| 568 |
<p> |
| 569 |
Compatibility can only be claimed if both rules are true. |
| 570 |
The frontend can use the |
| 571 |
<a class='info' href='#GET SERVER INFO'>"GET SERVER INFO"<span> (</span><span class='info'>General sampler informations</span><span>)</span></a> command to |
| 572 |

Introduction</h3> |
| 579 |
|
| 580 |
<p>LinuxSampler is a so called software sampler application |
| 581 |
capable to playback audio samples from a computer's Random |
| 582 |
Access Memory (RAM) as well as directly streaming it from disk. |
| 583 |
LinuxSampler is designed to be modular. It provides several so |
| 584 |
called "sampler engines" where each engine is specialized for a |
| 585 |
certain purpose. LinuxSampler has virtual channels which will be |
| 586 |
referred in this document as "sampler channels". The channels |
| 587 |
are in such way virtual as they can be connected to an |
| 588 |
arbitrary MIDI input method and arbitrary MIDI channel (e.g. |
| 589 |
sampler channel 17 could be connected to an ALSA sequencer |
| 590 |
device 64:0 and listening to MIDI channel 1 there). Each sampler |
| 591 |
channel will be associated with an instance of one of the available |
| 592 |
sampler engines (e.g. GigEngine, DLSEngine). The audio output of |
| 593 |
each sampler channel can be routed to an arbitrary audio output |
| 594 |
method (ALSA / JACK) and an arbitrary audio output channel |
| 595 |
there. |

Communication Overview</h3> |
| 614 |
|
| 615 |
<p>There are two distinct methods of communication between a |
| 616 |
running instance of LinuxSampler and one or more control |
| 617 |
applications, so called "front-ends": a simple request/response |
| 618 |
communication method used by the clients to give commands to the |
| 619 |
server as well as to inquire about server's status and a |
| 620 |
subscribe/notify communication method used by the client to |
| 621 |
subscribe to and receive notifications of certain events as they |
| 622 |
happen on the server. The latter needs more effort to be |
| 623 |
implemented in the front-end application. The two communication |
| 624 |
methods will be described next. |
| 625 |
</p> |
| 626 |
<a name="anchor5"></a><br /><hr /> |
| 627 |
<table summary="layout" cellpadding="0" cellspacing="2" class="TOCbug" align="right"><tr><td class="TOCbug"><a href="#toc"> TOC </a></td></tr></table> |
| 628 |
<a name="rfc.section.5.1"></a><h3>5.1. |
| 629 |
Request/response communication method</h3> |
| 630 |
|
| 631 |
<p>This simple communication method is based on |
| 632 |
<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 |
| 633 |
front-end application establishes a TCP connection to the |
| 634 |
LinuxSampler instance on a certain host system. Then the |
| 635 |
front-end application will send certain ASCII based commands |
| 636 |
as defined in this document (every command line must be CRLF |
| 637 |
terminated - see "Conventions used in this document" at the |
| 638 |
beginning of this document) and the LinuxSampler application |
| 639 |
will response after a certain process time with an |
| 640 |
appropriate ASCII based answer, also as defined in this |
| 641 |
document. So this TCP communication is simply based on query |
| 642 |
and answer paradigm. That way LinuxSampler is only able to |
| 643 |
answer on queries from front-ends, but not able to |
| 644 |
automatically send messages to the client if it's not asked |
| 645 |
to. The fronted should not reconnect to LinuxSampler for |
| 646 |
every single command, instead it should keep the connection |
| 647 |
established and simply resend message(s) for subsequent |
| 648 |
commands. To keep information in the front-end up-to-date |
| 649 |
the front-end has to periodically send new requests to get |
| 650 |
the current information from the LinuxSampler instance. This |
| 651 |
is often referred to as "polling". While polling is simple |
| 652 |
to implement and may be OK to use in some cases, there may |
| 653 |
be disadvantages to polling such as network traffic overhead |
| 654 |
and information being out of date. |
| 655 |
It is possible for a client or several clients to open more |
| 656 |
than one connection to the server at the same time. It is |
| 657 |
also possible to send more than one request to the server |
| 658 |
at the same time but if those requests are sent over the |
| 659 |
same connection server MUST execute them sequentially. Upon |
| 660 |
executing a request server will produce a result set and |
| 661 |
send it to the client. Each and every request made by the |
| 662 |
client MUST result in a result set being sent back to the |
| 663 |
client. No other data other than a result set may be sent by |
| 664 |
a server to a client. No result set may be sent to a client |
| 665 |
without the client sending request to the server first. On |
| 666 |
any particular connection, result sets MUST be sent in their |
| 667 |
entirety without being interrupted by other result sets. If |
| 668 |
several requests got queued up at the server they MUST be |
| 669 |
processed in the order they were received and result sets |
| 670 |
MUST be sent back in the same order. |

Subscribe/notify communication method</h3> |
| 869 |
|
| 870 |
<p>This more sophisticated communication method is actually |
| 871 |
only an extension of the simple request/response |
| 872 |
communication method. The front-end still uses a TCP |
| 873 |
connection and sends the same commands on the TCP |
| 874 |
connection. Two extra commands are SUBSCRIBE and UNSUBSCRIBE |
| 875 |
commands that allow a client to tell the server that it is |
| 876 |
interested in receiving notifications about certain events |
| 877 |
as they happen on the server. The SUBSCRIBE command has the |
| 878 |
following syntax: |
| 879 |
</p> |
| 880 |
<p> |
| 881 |
</p> |
| 882 |
<blockquote class="text"> |
| 883 |
<p>SUBSCRIBE <event-id> |
| 884 |
</p> |
| 885 |
</blockquote><p> |
| 886 |
|
| 887 |
</p> |
| 888 |
<p>where <event-id> will be replaced by the respective |
| 889 |
event that client wants to subscribe to. Upon receiving such |
| 890 |
request, server SHOULD respond with OK and start sending |
| 891 |
EVENT notifications when a given even has occurred to the |
| 892 |
front-end when an event has occurred. It MAY be possible |
| 893 |
certain events may be sent before OK response during real |
| 894 |
time nature of their generation. Event messages have the |
| 895 |
following format: |
| 896 |
</p> |
| 897 |
<p> |
| 898 |
</p> |
| 899 |
<blockquote class="text"> |
| 900 |
<p>NOTIFY:<event-id>:<custom-event-data> |
| 901 |
</p> |
| 902 |
</blockquote><p> |
| 903 |
|
| 904 |
</p> |
| 905 |
<p>where <event-id> uniquely identifies the event that |
| 906 |
has occurred and <custom-event-data> is event |
| 907 |
specific. |
| 908 |
</p> |
| 909 |
<p>Several rules must be followed by the server when |
| 910 |
generating events: |
| 911 |
</p> |
| 912 |
<p> |
| 913 |
</p> |
| 914 |
<ol class="text"> |
| 915 |
<li>Events MUST NOT be sent to any client who has not |
| 916 |
issued an appropriate SUBSCRIBE command. |
| 917 |
</li> |
| 918 |
<li>Events MUST only be sent using the same |
| 919 |
connection that was used to subscribe to them. |
| 920 |
</li> |
| 921 |
<li>When response is being sent to the client, event |
| 922 |
MUST be inserted in the stream before or after the |
| 923 |
response, but NOT in the middle. Same is true about |
| 924 |
the response. It should never be inserted in the |
| 925 |
middle of the event message as well as any other |
| 926 |
response. |
| 927 |
</li> |
| 928 |
</ol><p> |
| 929 |
|
| 930 |
</p> |
| 931 |
<p>If the client is not interested in a particular event |
| 932 |
anymore it MAY issue UNSUBSCRIBE command using the following |
| 933 |
syntax: |
| 934 |
</p> |
| 935 |
<p> |
| 936 |
</p> |
| 937 |
<blockquote class="text"> |
| 938 |
<p>UNSUBSCRIBE <event-id> |
| 939 |
</p> |
| 940 |
</blockquote><p> |
| 941 |
|
| 942 |
</p> |
| 943 |
<p>where <event-id> will be replace by the respective |
| 944 |
event that client is no longer interested in receiving. For |
| 945 |
a list of supported events see <a class='info' href='#events'>Section 8<span> (</span><span class='info'>Events</span><span>)</span></a>. |
| 946 |
</p> |
| 947 |
<p>Example: the fill states of disk stream buffers have |
| 948 |
changed on sampler channel 4 and the LinuxSampler instance |
| 949 |
will react by sending the following message to all clients |
| 950 |
who subscribed to this event: |
| 951 |
</p> |
| 952 |
<p> |
| 953 |
</p> |
| 954 |
<blockquote class="text"> |
| 955 |
<p>NOTIFY:CHANNEL_BUFFER_FILL:4 [35]62%,[33]80%,[37]98% |
| 956 |
</p> |
| 957 |
</blockquote><p> |
| 958 |
|
| 959 |
</p> |
| 960 |
<p>Which means there are currently three active streams on |
| 961 |
sampler channel 4, where the stream with ID "35" is filled |
| 962 |
by 62%, stream with ID 33 is filled by 80% and stream with |
| 963 |
ID 37 is filled by 98%. |
| 964 |
</p> |
| 965 |
<p>Clients may choose to open more than one connection to |
| 966 |
the server and use some connections to receive notifications |
| 967 |
while using other connections to issue commands to the |
| 968 |
back-end. This is entirely legal and up to the |
| 969 |
implementation. This does not change the protocol in any way |
| 970 |
and no special restrictions exist on the server to allow or |
| 971 |
disallow this or to track what connections belong to what |
| 972 |
front-ends. Server will listen on a single port, accept |
| 973 |
multiple connections and support protocol described in this |
| 974 |
specification in it's entirety on this single port on each |
| 975 |
connection that it accepted. |
| 976 |
</p> |
| 977 |
<p>Due to the fact that TCP is used for this communication, |
| 978 |
dead peers will be detected automatically by the OS TCP |
| 979 |
stack. While it may take a while to detect dead peers if no |
| 980 |
traffic is being sent from server to client (TCP keep-alive |
| 981 |
timer is set to 2 hours on many OSes) it will not be an |
| 982 |
issue here as when notifications are sent by the server, |
| 983 |
dead client will be detected quickly. |
| 984 |
</p> |
| 985 |
<p>When connection is closed for any reason server MUST |
| 986 |
forget all subscriptions that were made on this connection. |
| 987 |
If client reconnects it MUST resubscribe to all events that |
| 988 |
it wants to receive. |

| 1016 |
Configuring audio drivers</h3> |
| 1017 |
|
| 1018 |
<p>Instances of drivers in LinuxSampler are called devices. |
| 1019 |
You can use multiple audio devices simultaneously, e.g. to |
| 1020 |
output the sound of one sampler channel using the ALSA audio |
| 1021 |
output driver, and on another sampler channel you might want |
| 1022 |
to use the JACK audio output driver. For particular audio |
| 1023 |
output systems it's also possible to create several devices |
| 1024 |
of the same audio output driver, e.g. two separate ALSA |
| 1025 |
audio output devices for using two different sound cards at |
| 1026 |
the same time. This chapter describes all commands to |
| 1027 |
configure LinuxSampler's audio output devices and their |
| 1028 |
parameters. |
| 1029 |
</p> |
| 1030 |
<p>Instead of defining commands and parameters for each |
| 1031 |
driver individually, all possible parameters, their meanings |
| 1032 |
and possible values have to be obtained at runtime. This |
| 1033 |
makes the protocol a bit abstract, but has the advantage, |
| 1034 |
that front-ends can be written independently of what drivers |
| 1035 |
are currently implemented and what parameters these drivers |
| 1036 |
are actually offering. This means front-ends can even handle |
| 1037 |
drivers which are implemented somewhere in future without |
| 1038 |
modifying the front-end at all. |
| 1039 |
</p> |
| 1040 |
<p>Note: examples in this chapter showing particular |
| 1041 |
parameters of drivers are not meant as specification of the |
| 1042 |
drivers' parameters. Driver implementations in LinuxSampler |
| 1043 |
might have complete different parameter names and meanings |
| 1044 |
than shown in these examples or might change in future, so |
| 1045 |
these examples are only meant for showing how to retrieve |
| 1046 |
what parameters drivers are offering, how to retrieve their |
| 1047 |
possible values, etc. |

Configuring MIDI input drivers</h3> |
| 2264 |
|
| 2265 |
<p>Instances of drivers in LinuxSampler are called devices. You can use |
| 2266 |
multiple MIDI devices simultaneously, e.g. to use MIDI over ethernet as |
| 2267 |
MIDI input on one sampler channel and ALSA as MIDI input on another sampler |
| 2268 |
channel. For particular MIDI input systems it's also possible to create |
| 2269 |
several devices of the same MIDI input type. This chapter describes all |
| 2270 |
commands to configure LinuxSampler's MIDI input devices and their parameters. |
| 2271 |
</p> |
| 2272 |
<p>Instead of defining commands and parameters for each driver individually, |
| 2273 |
all possible parameters, their meanings and possible values have to be obtained |
| 2274 |
at runtime. This makes the protocol a bit abstract, but has the advantage, that |
| 2275 |
front-ends can be written independently of what drivers are currently implemented |
| 2276 |
and what parameters these drivers are actually offering. This means front-ends can |
| 2277 |
even handle drivers which are implemented somewhere in future without modifying |
| 2278 |
the front-end at all. |
| 2279 |
</p> |
| 2280 |
<p>Commands for configuring MIDI input devices are pretty much the same as the |
| 2281 |
commands for configuring audio output drivers, already described in the last |
| 2282 |
chapter. |
| 2283 |
</p> |
| 2284 |
<p>Note: examples in this chapter showing particular parameters of drivers are |
| 2285 |
not meant as specification of the drivers' parameters. Driver implementations in |
| 2286 |
LinuxSampler might have complete different parameter names and meanings than shown |
| 2287 |
in these examples or might change in future, so these examples are only meant for |
| 2288 |
showing how to retrieve what parameters drivers are offering, how to retrieve their |
| 2289 |
possible values, etc. |

Loading an instrument</h3> |
| 3305 |
|
| 3306 |
<p>An instrument file can be loaded and assigned to a sampler channel by one of the following commands: |
| 3307 |
</p> |
| 3308 |
<p> |
| 3309 |
</p> |
| 3310 |
<blockquote class="text"> |

<p>LOAD INSTRUMENT [NON_MODAL] '<filename>' <instr-index> <sampler-channel> |

| 3313 |
</blockquote><p> |
| 3314 |
|
| 3315 |
</p> |
| 3316 |
<p>Where <filename> is the name of the instrument file on the |
| 3317 |
LinuxSampler instance's host system, <instr-index> the index of the |
| 3318 |
instrument in the instrument file and <sampler-channel> is the |
| 3319 |
number of the sampler channel the instrument should be assigned to. |
| 3320 |
Each sampler channel can only have one instrument. |
| 3321 |
</p> |
| 3322 |
<p>The difference between regular and NON_MODAL versions of the command |
| 3323 |
is that the regular command returns OK only after the instrument has been |
| 3324 |
fully loaded and the channel is ready to be used while NON_MODAL version |
| 3325 |
returns immediately and a background process is launched to load the instrument |
| 3326 |
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> |
| 3327 |
command can be used to obtain loading |
| 3328 |
progress from INSTRUMENT_STATUS field. LOAD command will perform sanity checks |
| 3329 |
such as making sure that the file could be read and it is of a proper format |
| 3330 |
and SHOULD return ERR and SHOULD not launch the background process should any |
| 3331 |
errors be detected at that point. |

Adding an effect send to a sampler channel</h3> |
| 4982 |
|
| 4983 |
<p>The front-end can create an additional effect send on a specific sampler channel |
| 4984 |
by sending the following command: |
| 4985 |
</p> |
| 4986 |
<p> |
| 4987 |
</p> |
| 4988 |
<blockquote class="text"> |
| 4989 |
<p>CREATE FX_SEND <sampler-channel> <midi-ctrl> [<name>] |
| 4990 |
</p> |
| 4991 |
</blockquote><p> |
| 4992 |
|
| 4993 |
</p> |
| 4994 |
<p>Where <sampler-channel> is the respective sampler channel |
| 4995 |
number as returned by the <a class='info' href='#ADD CHANNEL'>"ADD CHANNEL"<span> (</span><span class='info'>Adding a new sampler channel</span><span>)</span></a> |
| 4996 |
or <a class='info' href='#LIST CHANNELS'>"LIST CHANNELS"<span> (</span><span class='info'>Getting all created sampler channel list</span><span>)</span></a> command, that is the |
| 4997 |
sampler channel on which the effect send should be created on, <midi-ctrl> |
| 4998 |
is a number between 0..127 defining the MIDI controller which can alter the |
| 4999 |
effect send level and <name> is an optional argument defining a name |
| 5000 |
for the effect send entity. The name does not have to be unique. |
| 5001 |
</p> |
| 5002 |
<p>By default, that is as initial routing, the effect send's audio channels |
| 5003 |
are automatically routed to the last audio channels of the sampler channel's |
| 5004 |
audio output device, that way you can i.e. first increase the amount of audio |
| 5005 |
channels on the audio output device for having dedicated effect send output |
| 5006 |
channels and when "CREATE FX_SEND" is called, those channels will automatically |
| 5007 |
be picked. You can alter the destination channels however with |
| 5008 |
<a class='info' href='#SET FX_SEND AUDIO_OUTPUT_CHANNEL'>"SET FX_SEND AUDIO_OUTPUT_CHANNEL"<span> (</span><span class='info'>Altering effect send's audio routing</span><span>)</span></a>. |
| 5009 |
|
| 5010 |
</p> |
| 5011 |
<p>Note: Create effect sends on a sampler channel only when needed, because having effect |
| 5012 |
sends on a sampler channel will decrease runtime performance, because for implementing channel |
| 5013 |
effect sends, separate (sampler channel local) audio buffers are needed to render and mix |
| 5014 |
the voices and route the audio signal afterwards to the master outputs and effect send |
| 5015 |
outputs (along with their respective effect send levels). A sampler channel without effect |
| 5016 |
sends however can mix its voices directly into the audio output devices's audio buffers |
| 5017 |
and is thus faster. |

device as assigned to the effect send's sampler channel. Also note that an |
| 5365 |
effect send entity does always have exactly as much audio channels as its |
| 5366 |
sampler channel. So if the sampler channel is stereo, the effect send does |
| 5367 |
have two audio channels as well. Also keep in mind that the amount of audio |
| 5368 |
channels on a sampler channel might be dependant not only to the deployed |
| 5369 |
sampler engine on the sampler channel, but also dependant to the instrument |
| 5370 |
currently loaded. However you can (effectively) turn an i.e. stereo effect |
| 5371 |
send into a mono one by simply altering its audio routing appropriately. |

MIDI Instrument Mapping</h3> |
| 6097 |
|
| 6098 |
<p>The MIDI protocol provides a way to switch between instruments |
| 6099 |
by sending so called MIDI bank select and MIDI program change |
| 6100 |
messages which are essentially just numbers. The following commands |
| 6101 |
allow to actually map arbitrary MIDI bank select / program change |
| 6102 |
numbers with real instruments. |
| 6103 |
</p> |
| 6104 |
<p>The sampler allows to manage an arbitrary amount of MIDI |
| 6105 |
instrument maps which define which instrument to load on |
| 6106 |
which MIDI program change message. |
| 6107 |
</p> |
| 6108 |
<p>By default, that is when the sampler is launched, there is no |
| 6109 |
map, thus the sampler will simply ignore all program change |
| 6110 |
messages. The front-end has to explicitly create at least one |
| 6111 |
map, add entries to the map and tell the respective sampler |
| 6112 |
channel(s) which MIDI instrument map to use, so the sampler |
| 6113 |
knows how to react on a given program change message on the |
| 6114 |
respective sampler channel, that is by switching to the |
| 6115 |
respectively defined engine type and loading the respective |
| 6116 |
instrument. See command |
| 6117 |
<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> |
| 6118 |
for how to assign a MIDI instrument map to a sampler channel. |
| 6119 |
</p> |
| 6120 |
<p>Also note per MIDI specification a bank select message does not |
| 6121 |
cause to switch to another instrument. Instead when receiving a |
| 6122 |
bank select message the bank value will be stored and a subsequent |
| 6123 |
program change message (which may occur at any time) will finally |
| 6124 |
cause the sampler to switch to the respective instrument as |
| 6125 |
reflected by the current MIDI instrument map. |

The <instr_load_mode> argument thus allows to define an |
| 6595 |
appropriate strategy (low memory consumption vs. fast |
| 6596 |
instrument switching) for each instrument individually. Note, the |
| 6597 |
following restrictions apply to this argument: "ON_DEMAND_HOLD" and |
| 6598 |
"PERSISTENT" have to be supported by the respective sampler engine |
| 6599 |
(which is technically the case when the engine provides an |
| 6600 |
InstrumentManager for its format). If this is not the case the |
| 6601 |
argument will automatically fall back to the default value |
| 6602 |
"ON_DEMAND". Also the load mode of one instrument may |
| 6603 |
automatically change the laod mode of other instrument(s), i.e. |
| 6604 |
because the instruments are part of the same file and the |
| 6605 |
engine does not allow a way to manage load modes for them |
| 6606 |
individually. Due to this, in case the frontend shows the |
| 6607 |
load modes of entries, the frontend should retrieve the actual |
| 6608 |
mode by i.e. sending |
| 6609 |
<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> |
| 6610 |
command(s). Finally the OPTIONAL <name> argument allows to |
| 6611 |
set a custom name (encapsulated into apostrophes) for the mapping |
| 6612 |
entry, useful for frontends for displaying an appropriate name for |
| 6613 |
mapped instruments (using |
| 6614 |
<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>). |
| 6615 |
|
| 6616 |
</p> |
| 6617 |
<p> |
| 6618 |
By default, "MAP MIDI_INSTRUMENT" commands block until the mapping is |
| 6619 |
completely established in the sampler. The OPTIONAL "NON_MODAL" argument |
| 6620 |
however causes the respective "MAP MIDI_INSTRUMENT" command to return |
| 6621 |
immediately, that is to let the sampler establish the mapping in the |
| 6622 |
background. So this argument might be especially useful for mappings with |
| 6623 |
a "PERSISTENT" type, because these have to load the respective instruments |
| 6624 |
immediately and might thus block for a very long time. It is recommended |
| 6625 |
however to use the OPTIONAL "NON_MODAL" argument only if really necessary, |
| 6626 |
because it has the following drawbacks: as "NON_MODAL" instructions return |
| 6627 |
immediately, they may not necessarily return an error i.e. when the given |
| 6628 |
instrument file turns out to be corrupt, beside that subsequent commands |
| 6629 |
in a LSCP instruction sequence might fail, because mandatory mappings are |
| 6630 |
not yet completed. |

<p>where <device-id> will be replaced by the numerical ID of the audio output device, |
| 8035 |
which settings has been changed. The front-end will have to send |
| 8036 |
the respective command to actually get the audio output device info. Because these messages |
| 8037 |
will be triggered by LSCP commands issued by other clients rather than real |
| 8038 |
time events happening on the server, it is believed that an empty notification |
| 8039 |
message is sufficient here. |

the location of the changed MIDI instrument in the map. The front-end will have to send |
| 8466 |
the respective command to actually get the MIDI instrument info. Because these messages |

will be triggered by LSCP commands issued by other clients rather than real |
| 8468 |
time events happening on the server, it is believed that an empty notification |

message is sufficient here. |

Security Considerations</h3> |

|

<p>As there is so far no method of authentication and authorization |
| 8536 |
defined and so not required for a client applications to succeed to |
| 8537 |
connect, running LinuxSampler might be a security risk for the host |
