<section title="Adding an effect send to a sampler channel" anchor="CREATE FX_SEND"> |
| 3231 |
|
<t>The front-end can create an additional effect send on a specific sampler channel |
| 3232 |
|
by sending the following command:</t> |
| 3233 |
|
<t> |
| 3234 |
|
<list> |
| 3235 |
|
<t>CREATE FX_SEND <sampler-channel> <midi-ctrl> [<name>]</t> |
| 3236 |
|
</list> |
| 3237 |
|
</t> |
| 3238 |
|
<t>Where <sampler-channel> is the respective sampler channel |
| 3239 |
|
number as returned by the <xref target="ADD CHANNEL">"ADD CHANNEL"</xref> |
| 3240 |
|
or <xref target="LIST CHANNELS">"LIST CHANNELS"</xref> command, that is the |
| 3241 |
|
sampler channel on which the effect send should be created on, <midi-ctrl> |
| 3242 |
|
is a number between 0..127 defining the MIDI controller which can alter the |
| 3243 |
|
effect send level and <name> is an optional argument defining a name |
| 3244 |
|
for the effect send entity. The name does not have to be unique.</t> |
| 3245 |
|
|
| 3246 |
|
<t>By default, that is as initial routing, the effect send's audio channels |
| 3247 |
|
are automatically routed to the last audio channels of the sampler channel's |
| 3248 |
|
audio output device, that way you can i.e. first increase the amount of audio |
| 3249 |
|
channels on the audio output device for having dedicated effect send output |
| 3250 |
|
channels and when "CREATE FX_SEND" is called, those channels will automatically |
| 3251 |
|
be picked. You can alter the destination channels however with |
| 3252 |
|
<xref target="SET FX_SEND AUDIO_OUTPUT_CHANNEL">"SET FX_SEND AUDIO_OUTPUT_CHANNEL"</xref>. |
| 3253 |
|
</t> |
| 3254 |
|
|
| 3255 |
|
<t>Note: Create effect sends on a sampler channel only when needed, because having effect |
| 3256 |
|
sends on a sampler channel will decrease runtime performance, because for implementing channel |
| 3257 |
|
effect sends, separate (sampler channel local) audio buffers are needed to render and mix |
| 3258 |
|
the voices and route the audio signal afterwards to the master outputs and effect send |
| 3259 |
|
outputs (along with their respective effect send levels). A sampler channel without effect |
| 3260 |
|
sends however can mix its voices directly into the audio output devices's audio buffers |
| 3261 |
|
and is thus faster. |

<audio-src> is the numerical ID of the effect send's audio channel |

| 3500 |
|
|
| 3501 |
|
<t>Note that effect sends can only route audio to the same audio output |
| 3502 |
|
device as assigned to the effect send's sampler channel. Also note that an |
| 3503 |
|
effect send entity does always have exactly as much audio channels as its |
| 3504 |
|
sampler channel. So if the sampler channel is stereo, the effect send does |
| 3505 |
|
have two audio channels as well. Also keep in mind that the amount of audio |
| 3506 |
|
channels on a sampler channel might be dependant not only to the deployed |
| 3507 |
|
sampler engine on the sampler channel, but also dependant to the instrument |
| 3508 |
|
currently loaded. However you can (effectively) turn an i.e. stereo effect |
| 3509 |
|
send into a mono one by simply altering its audio routing appropriately.</t> |

<section title="MIDI Instrument Mapping" anchor="MIDI Instrument Mapping"> |
| 3991 |
|
<t>The MIDI protocol provides a way to switch between instruments |
| 3992 |
|
by sending so called MIDI bank select and MIDI program change |
| 3993 |
|
messages which are essentially just numbers. The following commands |
| 3994 |
|
allow to actually map arbitrary MIDI bank select / program change |
| 3995 |
|
numbers with real instruments.</t> |
| 3996 |
|
<t>The sampler allows to manage an arbitrary amount of MIDI |
| 3997 |
|
instrument maps which define which instrument to load on |
| 3998 |
|
which MIDI program change message.</t> |
| 3999 |
|
<t>By default, that is when the sampler is launched, there is no |
| 4000 |
|
map, thus the sampler will simply ignore all program change |
| 4001 |
|
messages. The front-end has to explicitly create at least one |
| 4002 |
|
map, add entries to the map and tell the respective sampler |
| 4003 |
|
channel(s) which MIDI instrument map to use, so the sampler |
| 4004 |
|
knows how to react on a given program change message on the |
| 4005 |
|
respective sampler channel, that is by switching to the |
| 4006 |
|
respectively defined engine type and loading the respective |
| 4007 |
|
instrument. See command |
| 4008 |
|
<xref target="SET CHANNEL MIDI_INSTRUMENT_MAP">"SET CHANNEL MIDI_INSTRUMENT_MAP"</xref> |
| 4009 |
|
for how to assign a MIDI instrument map to a sampler channel.</t> |
| 4010 |
|
<t>Also note per MIDI specification a bank select message does not |
| 4011 |
|
cause to switch to another instrument. Instead when receiving a |
| 4012 |
|
bank select message the bank value will be stored and a subsequent |
| 4013 |
|
program change message (which may occur at any time) will finally |
| 4014 |
|
cause the sampler to switch to the respective instrument as |
| 4015 |
|
reflected by the current MIDI instrument map.</t> |

volume of the instrument as optionally dotted number (where a |

argument given, it will be up to the |

|
Usually it will use "ON_DEMAND" if an entry |
| 4329 |
|
for the given instrument does not exist in |
| 4330 |
|
the InstrumentManager's list yet, otherwise |
| 4331 |
|
if an entry already exists, it will simply |
| 4332 |

not change the mode.</t> |

| 4340 |
|
The <instr_load_mode> argument thus allows to define an |
| 4341 |
|
appropriate strategy (low memory consumption vs. fast |
| 4342 |
|
instrument switching) for each instrument individually. Note, the |
| 4343 |
|
following restrictions apply to this argument: "ON_DEMAND_HOLD" and |
| 4344 |
|
"PERSISTENT" have to be supported by the respective sampler engine |
| 4345 |
|
(which is technically the case when the engine provides an |
| 4346 |
|
InstrumentManager for its format). If this is not the case the |
| 4347 |
|
argument will automatically fall back to the default value |
| 4348 |
|
"ON_DEMAND". Also the load mode of one instrument may |
| 4349 |
|
automatically change the laod mode of other instrument(s), i.e. |
| 4350 |
|
because the instruments are part of the same file and the |
| 4351 |
|
engine does not allow a way to manage load modes for them |
| 4352 |
|
individually. Due to this, in case the frontend shows the |
| 4353 |
|
load modes of entries, the frontend should retrieve the actual |
| 4354 |
|
mode by i.e. sending |
| 4355 |
|
<xref target="GET MIDI_INSTRUMENT INFO">"GET MIDI_INSTRUMENT INFO"</xref> |
| 4356 |
|
command(s). Finally the OPTIONAL <name> argument allows to |
| 4357 |
|
set a custom name (encapsulated into apostrophes) for the mapping |
| 4358 |
|
entry, useful for frontends for displaying an appropriate name for |
| 4359 |
|
mapped instruments (using |
| 4360 |
|
<xref target="GET MIDI_INSTRUMENT INFO">"GET MIDI_INSTRUMENT INFO"</xref>). |
| 4361 |
|
</t> |
| 4362 |
|
<t> |
| 4363 |
|
By default, "MAP MIDI_INSTRUMENT" commands block until the mapping is |
| 4364 |
|
completely established in the sampler. The OPTIONAL "NON_MODAL" argument |
| 4365 |
|
however causes the respective "MAP MIDI_INSTRUMENT" command to return |
| 4366 |
|
immediately, that is to let the sampler establish the mapping in the |
| 4367 |
|
background. So this argument might be especially useful for mappings with |
| 4368 |
|
a "PERSISTENT" type, because these have to load the respective instruments |
| 4369 |
|
immediately and might thus block for a very long time. It is recommended |
| 4370 |
|
however to use the OPTIONAL "NON_MODAL" argument only if really necessary, |
| 4371 |
|
because it has the following drawbacks: as "NON_MODAL" instructions return |
| 4372 |
|
immediately, they may not necessarily return an error i.e. when the given |
| 4373 |
|
instrument file turns out to be corrupt, beside that subsequent commands |
| 4374 |
|
in a LSCP instruction sequence might fail, because mandatory mappings are |
| 4375 |
|
not yet completed. |
