3368    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 6.4.31).
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.

3644    6.4.31.  Altering effect send's audio routing
3645    
3646       The front-end can alter the destination of an effect send's audio
3647       channel on a specific sampler channel by sending the following
3648       command:
3649    
3650          SET FX_SEND AUDIO_OUTPUT_CHANNEL <sampler-chan> <fx-send-id>
3651          <audio-src> <audio-dst>
3652    
3653       Where <sampler-chan> is the sampler channel number as returned by the
3654       "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4)
3655       command, <fx-send-id> reflects the numerical ID of the effect send
3656       entity as returned by the "CREATE FX_SEND" (Section 6.4.25) or "LIST
3657       FX_SENDS" (Section 6.4.28) command, <audio-src> is the numerical ID
3658       of the effect send's audio channel which should be rerouted and
3659       <audio-dst> is the numerical ID of the audio channel of the selected
3660       audio output device where <audio-src> should be routed to.
3661    
3662       Note that effect sends can only route audio to the same audio output
3663       device as assigned to the effect send's sampler channel.  Also note
3664       that an effect send entity does always have exactly as much audio
3665       channels as its sampler channel.  So if the sampler channel is
3666       stereo, the effect send does have two audio channels as well.  Also
3667       keep in mind that the amount of audio channels on a sampler channel
3668       might be dependant not only to the deployed sampler engine on the
3669       sampler channel, but also dependant to the instrument currently
3670       loaded.  However you can (effectively) turn an i.e. stereo effect
3671       send into a mono one by simply altering its audio routing
3672       appropriately.

4055          GET VOLUME
4056

4059          The sampler will always answer by returning the optional dotted
4060          floating point coefficient, reflecting the current global volume
4061          attenuation.
4062    
4063       Note: it is up to the respective sampler engine whether to obey that

4065       this parameter.

4074       Where <volume> should be replaced by the optional dotted floating
4075       point value, reflecting the new global volume parameter.  This value
4076       might usually be in the range between 0.0 and 1.0, that is for

4105    6.7.  MIDI Instrument Mapping
4106    
4107       The MIDI protocol provides a way to switch between instruments by
4108       sending so called MIDI bank select and MIDI program change messages
4109       which are essentially just numbers.  The following commands allow to
4110       actually map arbitrary MIDI bank select / program change numbers with
4111       real instruments.
4112    
4113       The sampler allows to manage an arbitrary amount of MIDI instrument
4114       maps which define which instrument to load on which MIDI program
4115       change message.
4116    
4117       By default, that is when the sampler is launched, there is no map,
4118       thus the sampler will simply ignore all program change messages.  The
4119       front-end has to explicitly create at least one map, add entries to
4120       the map and tell the respective sampler channel(s) which MIDI
4121       instrument map to use, so the sampler knows how to react on a given
4122       program change message on the respective sampler channel, that is by
4123       switching to the respectively defined engine type and loading the
4124       respective instrument.  See command "SET CHANNEL MIDI_INSTRUMENT_MAP"
4125       (Section 6.4.24) for how to assign a MIDI instrument map to a sampler
4126       channel.
4127    
4128       Also note per MIDI specification a bank select message does not cause
4129       to switch to another instrument.  Instead when receiving a bank
4130       select message the bank value will be stored and a subsequent program
4131       change message (which may occur at any time) will finally cause the
4132       sampler to switch to the respective instrument as reflected by the
4133       current MIDI instrument map.

4372       instrument as optionally dotted number (where a value < 1.0 means
4373       attenuation and a value > 1.0 means amplification).  This parameter
4374       easily allows to adjust the volume of all intruments within a custom
4375       instrument map without having to adjust their instrument files.  The
4376       OPTIONAL <instr_load_mode> argument defines the life time of the
4377       instrument, that is when the instrument should be loaded, when freed
4378       and has exactly the following possibilities:
4379    
4380          "ON_DEMAND" -
4381    
4382             The instrument will be loaded when needed, that is when
4383             demanded by at least one sampler channel.  It will immediately
4384             be freed from memory when not needed by any sampler channel
4385             anymore.
4386    
4387          "ON_DEMAND_HOLD" -
4388    
4389             The instrument will be loaded when needed, that is when
4390             demanded by at least one sampler channel.  It will be kept in
4391             memory even when not needed by any sampler channel anymore.
4392             Instruments with this mode are only freed when the sampler is
4393             reset or all mapping entries with this mode (and respective
4394             instrument) are explicitly changed to "ON_DEMAND" and no
4395             sampler channel is using the instrument anymore.
4396    
4397          "PERSISTENT" -
4398    
4399             The instrument will immediately be loaded into memory when this
4400             mapping command is sent and the instrument is kept all the
4401             time.  Instruments with this mode are only freed when the
4402             sampler is reset or all mapping entries with this mode (and
4403             respective instrument) are explicitly changed to "ON_DEMAND"
4404             and no sampler channel is using the instrument anymore.
4405    
4406          not supplied -
4407    
4408             In case there is no <instr_load_mode> argument given, it will
4409             be up to the InstrumentManager to decide which mode to use.
4410             Usually it will use "ON_DEMAND" if an entry for the given
4411             instrument does not exist in the InstrumentManager's list yet,
4412             otherwise if an entry already exists, it will simply stick with
4413             the mode currently reflected by the already existing entry,
4414             that is it will not change the mode.
4415    
4416       The <instr_load_mode> argument thus allows to define an appropriate
4417       strategy (low memory consumption vs. fast instrument switching) for
4418       each instrument individually.  Note, the following restrictions apply
4419       to this argument: "ON_DEMAND_HOLD" and "PERSISTENT" have to be

4428       supported by the respective sampler engine (which is technically the
4429       case when the engine provides an InstrumentManager for its format).
4430       If this is not the case the argument will automatically fall back to
4431       the default value "ON_DEMAND".  Also the load mode of one instrument
4432       may automatically change the laod mode of other instrument(s), i.e.
4433       because the instruments are part of the same file and the engine does
4434       not allow a way to manage load modes for them individually.  Due to
4435       this, in case the frontend shows the load modes of entries, the
4436       frontend should retrieve the actual mode by i.e. sending "GET
4437       MIDI_INSTRUMENT INFO" (Section 6.7.11) command(s).  Finally the
4438       OPTIONAL <name> argument allows to set a custom name (encapsulated
4439       into apostrophes) for the mapping entry, useful for frontends for
4440       displaying an appropriate name for mapped instruments (using "GET
4441       MIDI_INSTRUMENT INFO" (Section 6.7.11)).
4442    
4443       By default, "MAP MIDI_INSTRUMENT" commands block until the mapping is
4444       completely established in the sampler.  The OPTIONAL "NON_MODAL"
4445       argument however causes the respective "MAP MIDI_INSTRUMENT" command
4446       to return immediately, that is to let the sampler establish the
4447       mapping in the background.  So this argument might be especially
4448       useful for mappings with a "PERSISTENT" type, because these have to
4449       load the respective instruments immediately and might thus block for
4450       a very long time.  It is recommended however to use the OPTIONAL
4451       "NON_MODAL" argument only if really necessary, because it has the
4452       following drawbacks: as "NON_MODAL" instructions return immediately,
4453       they may not necessarily return an error i.e. when the given
4454       instrument file turns out to be corrupt, beside that subsequent
4455       commands in a LSCP instruction sequence might fail, because mandatory
4456       mappings are not yet completed.

4541    
4542       The front-end can query a list of all currently existing entries in a
4543       certain MIDI instrument map by sending the following command:
4544    
4545          LIST MIDI_INSTRUMENTS <map>
4546    
4547       Where <map> is the numeric ID of the MIDI instrument map.
4548    
4549       The front-end can query a list of all currently existing entries of
4550       all MIDI instrument maps by sending the following command:
4551    
4552          LIST MIDI_INSTRUMENTS ALL
4553    
4554       Possible Answers:
4555    
4556          The sampler will answer by sending a comma separated list of map
4557          ID - MIDI bank - MIDI program triples, where each triple is
4558          encapsulated into curly braces.  The list is returned in one
4559          single line.  Each triple just reflects the key of the respective
4560          map entry, thus subsequent "GET MIDI_INSTRUMENT INFO"
4561          (Section 6.7.11) command(s) are necessary to retrieve detailed
4562          informations about each entry.
4563    
4564       Example:
4565    
4566          C: "LIST MIDI_INSTRUMENTS 0"
4567    
4568          S: "{0,0,0},{0,0,1},{0,0,3},{0,1,4},{1,127,127}"

4574    
4575          UNMAP MIDI_INSTRUMENT <map> <midi_bank> <midi_prog>
4576    
4577       Where <map> is the numeric ID of the MIDI instrument map, <midi_bank>
4578       is an integer value between 0..16383 reflecting the MIDI bank value
4579       and <midi_prog> an integer value between 0..127 reflecting the MIDI
4580       program value of the map's entrie's key index triple.

4610    
4611          GET MIDI_INSTRUMENT INFO <map> <midi_bank> <midi_prog>
4612    
4613       Where <map> is the numeric ID of the MIDI instrument map, <midi_bank>
4614       is an integer value between 0..16383 reflecting the MIDI bank value,

4617       triple.
4618    
4619       Possible Answers:
4620    
4621          LinuxSampler will answer by sending a <CRLF> separated list.  Each
4622          answer line begins with the information category name followed by
4623          a colon and then a space character <SP> and finally the info
4624          character string to that info category.  At the moment the
4625          following categories are defined:
4626    
4627          "NAME" -
4628    
4629             Name for this MIDI instrument map entry (if defined).  This
4630             name shall be used by frontends for displaying a name for this
4631             mapped instrument.  It can be set and changed with the "MAP
4632             MIDI_INSTRUMENT" (Section 6.7.7) command and does not have to
4633             be unique.
4634    
4635          "ENGINE_NAME" -
4636    
4637             Name of the engine to be deployed for this instrument.
4638    
4639          "INSTRUMENT_FILE" -
4640    
4641             File name of the instrument.

4652          "INSTRUMENT_NR" -
4653    
4654             Index of the instrument within the file.
4655    
4656          "INSTRUMENT_NAME" -
4657    
4658             Name of the loaded instrument as reflected by its file.  In
4659             contrast to the "NAME" field, the "INSTRUMENT_NAME" field
4660             cannot be changed.
4661    
4662          "LOAD_MODE" -
4663    
4664             Life time of instrument (see "MAP MIDI_INSTRUMENT"
4665             (Section 6.7.7) for details about this setting).
4666    
4667          "VOLUME" -
4668    
4669             master volume of the instrument as optionally dotted number
4670             (where a value < 1.0 means attenuation and a value > 1.0 means
4671             amplification)

4710       Where <map> is the numeric ID of the map to clear.
4711    
4712       The front-end can clear all MIDI instrument maps, that is delete all
4713       entries of all maps by sending the following command:
4714    
4715          CLEAR MIDI_INSTRUMENTS ALL
4716    
4717       The command "CLEAR MIDI_INSTRUMENTS ALL" does not delete the maps,
4718       only their entries, thus the map's settings like custom name will be
4719       preservevd.
