6.4.25. Adding an effect send to a sampler channel |
3369 |
|
|
3370 |
|
The front-end can create an additional effect send on a specific |
3371 |
|
sampler channel by sending the following command: |
3372 |
|
|
3373 |
|
CREATE FX_SEND <sampler-channel> <midi-ctrl> [<name>] |
3374 |
|
|
3375 |
|
Where <sampler-channel> is the respective sampler channel number as |
3376 |
|
returned by the "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" |
3377 |
|
(Section 6.4.4) command, that is the sampler channel on which the |
3378 |
|
effect send should be created on, <midi-ctrl> is a number between |
3379 |
|
0..127 defining the MIDI controller which can alter the effect send |
3380 |
|
level and <name> is an optional argument defining a name for the |
3381 |
|
effect send entity. The name does not have to be unique. |
3382 |
|
|
3383 |
|
By default, that is as initial routing, the effect send's audio |
3384 |
|
channels are automatically routed to the last audio channels of the |
3385 |
|
sampler channel's audio output device, that way you can i.e. first |
3386 |
|
increase the amount of audio channels on the audio output device for |
3387 |
|
having dedicated effect send output channels and when "CREATE |
3388 |
|
FX_SEND" is called, those channels will automatically be picked. You |
3389 |
|
can alter the destination channels however with "SET FX_SEND |
3390 |
|
AUDIO_OUTPUT_CHANNEL" (Section 6.4.30). |
3391 |
|
|
3392 |
|
Note: Create effect sends on a sampler channel only when needed, |
3393 |
|
because having effect sends on a sampler channel will decrease |
3394 |
|
runtime performance, because for implementing channel effect sends, |
3395 |
|
separate (sampler channel local) audio buffers are needed to render |
3396 |
|
and mix the voices and route the audio signal afterwards to the |
3397 |
|
master outputs and effect send outputs (along with their respective |
3398 |
|
effect send levels). A sampler channel without effect sends however |
3399 |
|
can mix its voices directly into the audio output devices's audio |
3400 |
|
buffers and is thus faster. |

|
DESTROY FX_SEND <sampler-channel> <fx-send-id> |
3441 |
|
|
3442 |

|
returned by the "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" |
3444 |
|
(Section 6.4.4) command, that is the sampler channel from which the |
3445 |

effect send should be removed from and <fx-send-id> is the respective |
3446 |
|
effect send number as returned by the "CREATE FX_SEND" |

3548 |
|
answer line begins with the settings category name followed by a |
3549 |
|
colon and then a space character <SP> and finally the info |
3550 |
|
character string to that setting category. At the moment the |
3551 |
|
following categories are defined: |
3552 |
|
|
3553 |
|
|
3554 |
|
|
3555 |
|
NAME - |
3556 |
|
|
3557 |
|
name of the effect send entity |
3558 |
|
|
3559 |
|
MIDI_CONTROLLER - |
3560 |
|
|
3561 |
|
a value between 0 and 127 reflecting the MIDI controller |
3562 |
|
which is able to modify the effect send's send level |
3563 |
|
|
3564 |
|
LEVEL - |
3565 |
|
|
3566 |
|
optionally dotted number reflecting the effect send's |
3567 |
|
current send level (where a value < 1.0 means attenuation |
3568 |
|
and a value > 1.0 means amplification) |
3569 |
|
|
3570 |
|
AUDIO_OUTPUT_ROUTING - |
3571 |
|
|
3572 |
|
comma separated list which reflects to which audio channel |
3573 |
|
of the selected audio output device each effect send output |
3574 |
|
channel is routed to, e.g. "0,3" would mean the effect |
3575 |
|
send's output channel 0 is routed to channel 0 of the audio |
3576 |
|
output device and the effect send's output channel 1 is |
3577 |
|
routed to the channel 3 of the audio output device (see "SET |
3578 |
|

6.4.30. Altering effect send's audio routing |
3605 |
|
|
3606 |
|
The front-end can alter the destination of an effect send's audio |
3607 |
|
channel on a specific sampler channel by sending the following |
3608 |
|
command: |
3609 |
|
|
3610 |
|
SET FX_SEND AUDIO_OUTPUT_CHANNEL <sampler-chan> <fx-send-id> |
3611 |
|
<audio-src> <audio-dst> |
3612 |
|
|
3613 |
|
Where <sampler-chan> is the sampler channel number as returned by the |
3614 |
|
"ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4) |
3615 |
|
command, <fx-send-id> reflects the numerical ID of the effect send |
3616 |
|
entity as returned by the "CREATE FX_SEND" (Section 6.4.25) or "LIST |
3617 |
|
FX_SENDS" (Section 6.4.28) command, <audio-src> is the numerical ID |
3618 |
|
of the effect send's audio channel which should be rerouted and |
3619 |
|
<audio-dst> is the numerical ID of the audio channel of the selected |
3620 |
|
audio output device where <audio-src> should be routed to. |
3621 |
|
|
3622 |
|
Note that effect sends can only route audio to the same audio output |
3623 |
|
device as assigned to the effect send's sampler channel. Also note |
3624 |
|
that an effect send entity does always have exactly as much audio |
3625 |
|
channels as its sampler channel. So if the sampler channel is |
3626 |
|
stereo, the effect send does have two audio channels as well. Also |
3627 |
|
keep in mind that the amount of audio channels on a sampler channel |
3628 |
|
might be dependant not only to the deployed sampler engine on the |
3629 |
|
sampler channel, but also dependant to the instrument currently |
3630 |
|
loaded. However you can (effectively) turn an i.e. stereo effect |
3631 |
|
send into a mono one by simply altering its audio routing |
3632 |
|
appropriately. |

6.7. MIDI Instrument Mapping |
4068 |
|
|
4069 |
|
The MIDI protocol provides a way to switch between instruments by |
4070 |
|
sending so called MIDI bank select and MIDI program change messages |
4071 |
|
which are essentially just numbers. The following commands allow to |
4072 |
|
actually map arbitrary MIDI bank select / program change numbers with |
4073 |
|
real instruments. |
4074 |
|
|
4075 |
|
The sampler allows to manage an arbitrary amount of MIDI instrument |
4076 |
|
maps which define which instrument to load on which MIDI program |
4077 |
|
change message. |
4078 |
|
|
4079 |
|
By default, that is when the sampler is launched, there is no map, |
4080 |
|
thus the sampler will simply ignore all program change messages. The |
4081 |
|
front-end has to explicitly create at least one map, add entries to |
4082 |
|
the map and tell the respective sampler channel(s) which MIDI |
4083 |
|
instrument map to use, so the sampler knows how to react on a given |
4084 |
|
|
4085 |
|
|
4086 |
|

Internet-Draft LinuxSampler Control Protocol March 2007 |
4090 |

|
4091 |
|
|
4092 |
|
program change message on the respective sampler channel, that is by |
4093 |
|
switching to the respectively defined engine type and loading the |
4094 |
|
respective instrument. See command "SET CHANNEL MIDI_INSTRUMENT_MAP" |
4095 |
|
(Section 6.4.24) for how to assign a MIDI instrument map to a sampler |
4096 |
|
channel. |
4097 |
|
|
4098 |
|
Also note per MIDI specification a bank select message does not cause |
4099 |
|
to switch to another instrument. Instead when receiving a bank |
4100 |
|
select message the bank value will be stored and a subsequent program |
4101 |
|
change message (which may occur at any time) will finally cause the |
4102 |
|
sampler to switch to the respective instrument as reflected by the |
4103 |
|
current MIDI instrument map. |
4104 |
|
|
4105 |
|
6.7.1. Create a new MIDI instrument map |
4106 |
|
|
4107 |
|
The front-end can add a new MIDI instrument map by sending the |
4108 |
|
following command: |
4109 |
|
|
4110 |
|
ADD MIDI_INSTRUMENT_MAP [<name>] |
4111 |
|
|
4112 |
|
Where <name> is an optional argument allowing to assign a custom name |
4113 |
|
to the new map. MIDI instrument Map names do not have to be unique. |
4114 |
|
|
4115 |
|
Possible Answers: |
4116 |
|
|
4117 |
|
"OK[<map>]" - |
4118 |
|
|
4119 |
|
in case a new MIDI instrument map could be added, where <map> |
4120 |
|
reflects the unique ID of the newly created MIDI instrument map |
4121 |
|
|
4122 |
|
"ERR:<error-code>:<error-message>" - |
4123 |

4318 |
|
[<instr_load_mode>] [<name>] |
4319 |
|
|
4320 |
|
Where <map> is the numeric ID of the map to alter, <midi_bank> is an |
4321 |
|
integer value between 0..16383 reflecting the MIDI bank select index, |
4322 |
|
<midi_prog> an integer value between 0..127 reflecting the MIDI |
4323 |
|
program change index, <engine_name> a sampler engine name as returned |
4324 |
|
by the "LIST AVAILABLE_ENGINES" (Section 6.4.8) command (not |
4325 |
|
encapsulated into apostrophes), <filename> the name of the |
4326 |
|
instrument's file to be deployed (encapsulated into apostrophes), |
4327 |
|
<instrument_index> the index (integer value) of the instrument within |
4328 |
|
the given file, <volume_value> reflects the master volume of the |
4329 |
|
instrument as optionally dotted number (where a value < 1.0 means |
4330 |
|
attenuation and a value > 1.0 means amplification). This parameter |
4331 |
|
easily allows to adjust the volume of all intruments within a custom |
4332 |
|
instrument map without having to adjust their instrument files. The |
4333 |
|
OPTIONAL <instr_load_mode> argument defines the life time of the |
4334 |
|
instrument, that is when the instrument should be loaded, when freed |
4335 |
|
and has exactly the following possibilities: |
4336 |
|
|
4337 |
|
"ON_DEMAND" - |
4338 |
|
|
4339 |
|
The instrument will be loaded when needed, that is when |
4340 |
|
demanded by at least one sampler channel. It will immediately |
4341 |
|
be freed from memory when not needed by any sampler channel |
4342 |
|
anymore. |
4343 |
|
|
4344 |
|
"ON_DEMAND_HOLD" - |
4345 |
|
|
4346 |
|
The instrument will be loaded when needed, that is when |
4347 |
|
demanded by at least one sampler channel. It will be kept in |
4348 |
|
memory even when not needed by any sampler channel anymore. |
4349 |
|
Instruments with this mode are only freed when the sampler is |
4350 |
|
reset or all mapping entries with this mode (and respective |
4351 |
|
instrument) are explicitly changed to "ON_DEMAND" and no |
4352 |
|
sampler channel is using the instrument anymore. |
4353 |
|
|
4354 |
|
"PERSISTENT" - |
4355 |
|
|
4356 |
|
The instrument will immediately be loaded into memory when this |
4357 |
|
mapping command is sent and the instrument is kept all the |
4358 |
|
time. Instruments with this mode are only freed when the |
4359 |
|
sampler is reset or all mapping entries with this mode (and |
4360 |
|
respective instrument) are explicitly changed to "ON_DEMAND" |
4361 |
|
and no sampler channel is using the instrument anymore. |

In case there is no <instr_load_mode> argument given, it will |

be up to the InstrumentManager to decide which mode to use. |
4376 |
|
Usually it will use "ON_DEMAND" if an entry for the given |
4377 |
|
instrument does not exist in the InstrumentManager's list yet, |
4378 |
|
otherwise if an entry already exists, it will simply stick with |

the mode currently reflected by the already existing entry, |
4380 |
|
that is it will not change the mode. |
4381 |
|
|
4382 |
|
The <instr_load_mode> argument thus allows to define an appropriate |
4383 |
|
strategy (low memory consumption vs. fast instrument switching) for |
4384 |
|
each instrument individually. Note, the following restrictions apply |
4385 |
|
to this argument: "ON_DEMAND_HOLD" and "PERSISTENT" have to be |
4386 |
|
supported by the respective sampler engine (which is technically the |
4387 |
|
case when the engine provides an InstrumentManager for its format). |
4388 |
|
If this is not the case the argument will automatically fall back to |
4389 |
|
the default value "ON_DEMAND". Also the load mode of one instrument |
4390 |
|
may automatically change the laod mode of other instrument(s), i.e. |
4391 |
|
because the instruments are part of the same file and the engine does |
4392 |
|
not allow a way to manage load modes for them individually. Due to |
4393 |
|
this, in case the frontend shows the load modes of entries, the |
4394 |
|
frontend should retrieve the actual mode by i.e. sending "GET |
4395 |
|
MIDI_INSTRUMENT INFO" (Section 6.7.11) command(s). Finally the |
4396 |
|
OPTIONAL <name> argument allows to set a custom name (encapsulated |
4397 |
|
into apostrophes) for the mapping entry, useful for frontends for |
4398 |
|
displaying an appropriate name for mapped instruments (using "GET |
4399 |
|
MIDI_INSTRUMENT INFO" (Section 6.7.11)). |
4400 |
|
|
4401 |
|
By default, "MAP MIDI_INSTRUMENT" commands block until the mapping is |
4402 |
|
completely established in the sampler. The OPTIONAL "NON_MODAL" |
4403 |
|
argument however causes the respective "MAP MIDI_INSTRUMENT" command |
4404 |
|
to return immediately, that is to let the sampler establish the |
4405 |
|
mapping in the background. So this argument might be especially |
4406 |
|
useful for mappings with a "PERSISTENT" type, because these have to |
4407 |
|
load the respective instruments immediately and might thus block for |
4408 |
|
a very long time. It is recommended however to use the OPTIONAL |
4409 |
|
"NON_MODAL" argument only if really necessary, because it has the |
4410 |
|
following drawbacks: as "NON_MODAL" instructions return immediately, |
4411 |
|
they may not necessarily return an error i.e. when the given |
4412 |
|
instrument file turns out to be corrupt, beside that subsequent |
4413 |
|
commands in a LSCP instruction sequence might fail, because mandatory |
4414 |
|
mappings are not yet completed. |

6.7.12. Clear MIDI instrument map |
4665 |
|
|
4666 |
|
The front-end can clear a whole MIDI instrument map, that is delete |
4667 |
|
all its entries by sending the following command: |
4668 |
|
|
4669 |
|
CLEAR MIDI_INSTRUMENTS <map> |
4670 |
|
|
4671 |
|
Where <map> is the numeric ID of the map to clear. |
4672 |
|
|
4673 |
|
The front-end can clear all MIDI instrument maps, that is delete all |
4674 |
|
entries of all maps by sending the following command: |
4675 |
|
|
4676 |
|
CLEAR MIDI_INSTRUMENTS ALL |
4677 |
|
|
4678 |
|
The command "CLEAR MIDI_INSTRUMENTS ALL" does not delete the maps, |
4679 |
|
only their entries, thus the map's settings like custom name will be |
4680 |
|
preservevd. |

5329 |
8.1. Number of sampler channels changed |
8.1. Number of audio output devices changed |
5330 |
|
|
5331 |
|
Client may want to be notified when the total number of audio output |
5332 |
|
devices on the back-end changes by issuing the following command: |
5333 |
|
|
5334 |
|
SUBSCRIBE AUDIO_OUTPUT_DEVICE_COUNT |
5335 |
|
|
5336 |
|
Server will start sending the following notification messages: |
5337 |
|
|
5338 |
|
"NOTIFY:AUDIO_OUTPUT_DEVICE_COUNT:<devices>" |
5339 |
|
|
5340 |
|
where <devices> will be replaced by the new number of audio output |
5341 |
|
devices. |
5342 |
|
|
5343 |
|
8.2. Audio output device's settings changed |
5344 |
|
|
5345 |
|
Client may want to be notified when changes were made to audio output |
5346 |
|
devices on the back-end by issuing the following command: |
5347 |
|
|
5348 |
|
SUBSCRIBE AUDIO_OUTPUT_DEVICE_INFO |
5349 |
|
|
5350 |
|
Server will start sending the following notification messages: |
5351 |
|
|
5352 |
|
"NOTIFY:AUDIO_OUTPUT_DEVICE_INFO:<device-id>" |
5353 |
|
|
5354 |
|
where <device-id> will be replaced by the numerical ID of the audio |
5355 |
|
output device, which settings has been changed. The front-end will |
5356 |
|
have to send the respective command to actually get the audio output |
5357 |
|
device info. Because these messages will be triggered by LSCP |
5358 |
|
commands issued by other clients rather than real time events |
5359 |
|
happening on the server, it is believed that an empty notification |
5360 |
|
message is sufficient here. |
5361 |
|
|
5362 |
|
8.3. Number of MIDI input devices changed |
5363 |
|
|
5364 |
|
Client may want to be notified when the total number of MIDI input |
5365 |
|
