3314       The front-end can assign a MIDI instrument map to a specific sampler
3315       channel by sending the following command:
3316    
3317          SET CHANNEL MIDI_INSTRUMENT_MAP <sampler-channel> <map>
3318

3321       (Section 6.4.4) command and <map> can have the following
3322       possibilites:
3323    
3324          "NONE" -
3325    
3326             This is the default setting.  In this case the sampler channel
3327             is not assigned any MIDI instrument map and thus will ignore
3328             all MIDI program change messages.
3329    
3330          "DEFAULT" -
3331    
3332             The sampler channel will always use the default MIDI instrument
3333             map to handle MIDI program change messages.
3334    
3335          numeric ID -
3336    
3337             You can assign a specific MIDI instrument map by replacing
3338             <map> with the respective numeric ID of the MIDI instrument map
3339             as returned by the "LIST MIDI_INSTRUMENT_MAPS" (Section 6.7.4)
3340             command.  Once that map will be deleted, the sampler channel
3341             would fall back to "NONE".

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 6.4.30).
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.

3547          The sampler will answer by sending a <CRLF> separated list.  Each
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                FX_SEND AUDIO_OUTPUT_CHANNEL" (Section 6.4.30) for details)

3604    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.

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

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.

4317          <engine_name> <filename> <instrument_index> <volume_value>
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.

4370    
4371    
4372          not supplied -
4373    
4374             In case there is no <instr_load_mode> argument given, it will
4375             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
4379             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.

4542       The front-end can delete an entry from a MIDI instrument map by
4543       sending the following command:
4544    
4545          UNMAP MIDI_INSTRUMENT <map> <midi_bank> <midi_prog>
4546    
4547       Where <map> is the numeric ID of the MIDI instrument map, <midi_bank>
4548       is an integer value between 0..16383 reflecting the MIDI bank value
4549       and <midi_prog> an integer value between 0..127 reflecting the MIDI
4550       program value of the map's entrie's key index triple.
4551    
4552       Possible Answers:
4553

4567    
4568    6.7.11.  Get current settings of MIDI instrument map entry
4569    
4570       The front-end can retrieve the current settings of a certain
4571       instrument map entry by sending the following command:
4572    
4573          GET MIDI_INSTRUMENT INFO <map> <midi_bank> <midi_prog>
4574    
4575       Where <map> is the numeric ID of the MIDI instrument map, <midi_bank>
4576       is an integer value between 0..16383 reflecting the MIDI bank value,
4577       <midi_bank> and <midi_prog> an integer value between 0..127
4578       reflecting the MIDI program value of the map's entrie's key index
4579       triple.

4583          LinuxSampler will answer by sending a <CRLF> separated list.  Each
4584          answer line begins with the information category name followed by
4585          a colon and then a space character <SP> and finally the info
4586          character string to that info category.  At the moment the
4587          following categories are defined:

4595    
4596          "NAME" -
4597    
4598             Name for this MIDI instrument map entry (if defined).  This
4599             name shall be used by frontends for displaying a name for this
4600             mapped instrument.  It can be set and changed with the "MAP
4601             MIDI_INSTRUMENT" (Section 6.7.7) command and does not have to
4602             be unique.
4603    
4604          "ENGINE_NAME" -
4605    
4606             Name of the engine to be deployed for this instrument.
4607    
4608          "INSTRUMENT_FILE" -
4609    
4610             File name of the instrument.
4611    
4612          "INSTRUMENT_NR" -
4613    
4614             Index of the instrument within the file.
4615    
4616          "INSTRUMENT_NAME" -
4617    
4618             Name of the loaded instrument as reflected by its file.  In
4619             contrast to the "NAME" field, the "INSTRUMENT_NAME" field
4620             cannot be changed.
4621    
4622          "LOAD_MODE" -
4623    
4624             Life time of instrument (see "MAP MIDI_INSTRUMENT"
4625             (Section 6.7.7) for details about this setting).
4626    
4627          "VOLUME" -
4628    
4629             master volume of the instrument as optionally dotted number
4630             (where a value < 1.0 means attenuation and a value > 1.0 means
4631             amplification)
4632    
4633          The mentioned fields above don't have to be in particular order.
4634    
4635       Example:
4636    
4637          C: "GET MIDI_INSTRUMENT INFO 1 45 120"
4638    
4639          S: "NAME: Drums for Foo Song"

4664    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.

    The IETF takes no position regarding the validity or scope of any  
    intellectual property or other rights that might be claimed to  
    pertain to the implementation or use of the technology described in  
    this document or the extent to which any license under such rights  
    might or might not be available; neither does it represent that it

    IETF's procedures with respect to rights in standards-track and  
    standards-related documentation can be found in BCP 11.  Copies of  
    claims of rights made available for publication and any assurances of

    proprietary rights by implementors or users of this specification can  
    be obtained from the IETF Secretariat.  
5805    
    The IETF invites any interested party to bring to its attention any  
    copyrights, patents or patent applications, or other proprietary  
    rights which may cover technology that may be required to practice
