3455    6.4.25.  Adding an effect send to a sampler channel
3456    
3457       The front-end can create an additional effect send on a specific
3458       sampler channel by sending the following command:
3459    
3460          CREATE FX_SEND <sampler-channel> <midi-ctrl> [<name>]

3467       level and <name> is an optional argument defining a name for the

3476       effect send entity.  The name does not have to be unique, but MUST be
3477       encapsulated into apostrophes and supports escape sequences as
3478       described in chapter "Character Set and Escape Sequences
3479       (Section 7.1)".
3480    
3481       By default, that is as initial routing, the effect send's audio
3482       channels are automatically routed to the last audio channels of the
3483       sampler channel's audio output device, that way you can i.e. first
3484       increase the amount of audio channels on the audio output device for
3485       having dedicated effect send output channels and when "CREATE
3486       FX_SEND" is called, those channels will automatically be picked.  You
3487       can alter the destination channels however with "SET FX_SEND
3488       AUDIO_OUTPUT_CHANNEL" (Section 6.4.31).
3489    
3490       Note: Create effect sends on a sampler channel only when needed,
3491       because having effect sends on a sampler channel will decrease
3492       runtime performance, because for implementing channel effect sends,
3493       separate (sampler channel local) audio buffers are needed to render
3494       and mix the voices and route the audio signal afterwards to the
3495       master outputs and effect send outputs (along with their respective
3496       effect send levels).  A sampler channel without effect sends however
3497       can mix its voices directly into the audio output devices's audio
3498       buffers and is thus faster.

3651                name of the effect send entity (note that this character
3652                string may contain escape sequences (Section 7.1))
3653    
3654             MIDI_CONTROLLER -
3655    
3656                a value between 0 and 127 reflecting the MIDI controller
3657                which is able to modify the effect send's send level
3658    
3659             LEVEL -
3660    
3661                optionally dotted number reflecting the effect send's
3662                current send level (where a value < 1.0 means attenuation
3663                and a value > 1.0 means amplification)
3664    
3665             AUDIO_OUTPUT_ROUTING -

3668                of the selected audio output device each effect send output
3669                channel is routed to, e.g. "0,3" would mean the effect
3670                send's output channel 0 is routed to channel 0 of the audio
3671                output device and the effect send's output channel 1 is
3672                routed to the channel 3 of the audio output device (see "SET

3700    6.4.30.  Changing effect send's name
3701    
3702       The front-end can alter the current name of an effect send entity by
3703       sending the following command:
3704

3708       "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4)
3709       command, <fx-send-id> reflects the numerical ID of the effect send
3710       entity as returned by the "CREATE FX_SEND" (Section 6.4.25) or "LIST
3711       FX_SENDS" (Section 6.4.28) command and <name> is the new name of the
3712       effect send entity, which does not have to be unique (name MUST be
3713       encapsulated into apostrophes and supports escape sequences as
3714       described in chapter "Character Set and Escape Sequences
3715       (Section 7.1)").
3716    
3717       Possible Answers:
3718    
3719          "OK" -

3721             on success
3722    
3723          "ERR:<error-code>:<error-message>" -

3734    6.4.31.  Altering effect send's audio routing
3735    
3736       The front-end can alter the destination of an effect send's audio
3737       channel on a specific sampler channel by sending the following
3738       command:
3739    
3740          SET FX_SEND AUDIO_OUTPUT_CHANNEL <sampler-chan> <fx-send-id>
3741          <audio-src> <audio-dst>
3742    
3743       Where <sampler-chan> is the sampler channel number as returned by the
3744       "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4)
3745       command, <fx-send-id> reflects the numerical ID of the effect send
3746       entity as returned by the "CREATE FX_SEND" (Section 6.4.25) or "LIST
3747       FX_SENDS" (Section 6.4.28) command, <audio-src> is the numerical ID

3756       of the effect send's audio channel which should be rerouted and
3757       <audio-dst> is the numerical ID of the audio channel of the selected
3758       audio output device where <audio-src> should be routed to.
3759    
3760       Note that effect sends can only route audio to the same audio output
3761       device as assigned to the effect send's sampler channel.  Also note
3762       that an effect send entity does always have exactly as much audio
3763       channels as its sampler channel.  So if the sampler channel is
3764       stereo, the effect send does have two audio channels as well.  Also
3765       keep in mind that the amount of audio channels on a sampler channel
3766       might be dependant not only to the deployed sampler engine on the
3767       sampler channel, but also dependant to the instrument currently
3768       loaded.  However you can (effectively) turn an i.e. stereo effect
3769       send into a mono one by simply altering its audio routing
3770       appropriately.

4169    6.6.6.  Getting global volume attenuation
4170    
4171       The client can ask for the current global sampler-wide volume
4172       attenuation by sending the following command:
4173    
4174          GET VOLUME
4175    
4176       Possible Answers:
4177    
4178          The sampler will always answer by returning the optional dotted
4179          floating point coefficient, reflecting the current global volume
4180          attenuation.
4181    
4182       Note: it is up to the respective sampler engine whether to obey that
4183       global volume parameter or not, but in general all engines SHOULD use
4184       this parameter.
4185    
4186    6.6.7.  Setting global volume attenuation
4187    
4188       The client can alter the current global sampler-wide volume
4189       attenuation by sending the following command:
4190    
4191          SET VOLUME <volume>
4192    
4193       Where <volume> should be replaced by the optional dotted floating
4194       point value, reflecting the new global volume parameter.  This value
4195       might usually be in the range between 0.0 and 1.0, that is for

4223    6.7.  MIDI Instrument Mapping
4224    
4225       The MIDI protocol provides a way to switch between instruments by
4226       sending so called MIDI bank select and MIDI program change messages
4227       which are essentially just numbers.  The following commands allow to
4228       actually map arbitrary MIDI bank select / program change numbers with
4229       real instruments.
4230    
4231       The sampler allows to manage an arbitrary amount of MIDI instrument
4232       maps which define which instrument to load on which MIDI program
4233       change message.
4234    
4235       By default, that is when the sampler is launched, there is no map,
4236       thus the sampler will simply ignore all program change messages.  The
4237       front-end has to explicitly create at least one map, add entries to
4238       the map and tell the respective sampler channel(s) which MIDI
4239       instrument map to use, so the sampler knows how to react on a given
4240       program change message on the respective sampler channel, that is by
4241       switching to the respectively defined engine type and loading the
4242       respective instrument.  See command "SET CHANNEL MIDI_INSTRUMENT_MAP"
4243       (Section 6.4.24) for how to assign a MIDI instrument map to a sampler
4244       channel.
4245    
4246       Also note per MIDI specification a bank select message does not cause
4247       to switch to another instrument.  Instead when receiving a bank
4248       select message the bank value will be stored and a subsequent program
4249       change message (which may occur at any time) will finally cause the
4250       sampler to switch to the respective instrument as reflected by the
4251       current MIDI instrument map.

4266    
4267       Where <name> is an optional argument allowing to assign a custom name
4268       to the new map.  MIDI instrument Map names do not have to be unique,
4269       but MUST be encapsulated into apostrophes and support escape
4270       sequences as described in chapter "Character Set and Escape Sequences
4271       (Section 7.1)".

4385    6.7.5.  Getting MIDI instrument map information
4386    
4387       The front-end can ask for the current settings of a MIDI instrument
4388       map by sending the following command:
4389    
4390          GET MIDI_INSTRUMENT_MAP INFO <map>
4391    
4392       Where <map> is the numerical ID of the map the front-end is
4393       interested in as returned by the "LIST MIDI_INSTRUMENT_MAPS"
4394       (Section 6.7.4) command.
4395    
4396       Possible Answers:
4397    
4398          LinuxSampler will answer by sending a <CRLF> separated list.  Each
4399          answer line begins with the settings category name followed by a
4400          colon and then a space character <SP> and finally the info
4401          character string to that setting category.  At the moment the

4439       sending the following command:
4440    
4441          SET MIDI_INSTRUMENT_MAP NAME <map> <name>
4442    
4443       Where <map> is the numerical ID of the map and <name> the new custom
4444       name of the map, which does not have to be unique (name MUST be
4445       encapsulated into apostrophes and supports escape sequences as
4446       described in chapter "Character Set and Escape Sequences
4447       (Section 7.1)").
4448    
4449       Possible Answers:
4450    
4451          "OK" -
4452    
4453             on success
4454    
4455          "ERR:<error-code>:<error-message>" -

4466    
4467       The front-end can create a new or replace an existing entry in a
4468       sampler's MIDI instrument map by sending the following command:
4469    
4470          MAP MIDI_INSTRUMENT [NON_MODAL] <map> <midi_bank> <midi_prog>
4471          <engine_name> <filename> <instrument_index> <volume_value>
4472          [<instr_load_mode>] [<name>]
4473    
4474       Where <map> is the numeric ID of the map to alter, <midi_bank> is an
4475       integer value between 0..16383 reflecting the MIDI bank select index,
4476

4481    Internet-Draft        LinuxSampler Control Protocol        December 2007
4482    
4483    
4484       <midi_prog> an integer value between 0..127 reflecting the MIDI
4485       program change index, <engine_name> a sampler engine name as returned
4486       by the "LIST AVAILABLE_ENGINES" (Section 6.4.8) command (not
4487       encapsulated into apostrophes), <filename> the name of the
4488       instrument's file to be deployed (encapsulated into apostrophes,
4489       supporting escape sequences as described in chapter "Character Set
4490       and Escape Sequences (Section 7.1)"), <instrument_index> the index
4491       (integer value) of the instrument within the given file,
4492       <volume_value> reflects the master volume of the instrument as
4493       optionally dotted number (where a value < 1.0 means attenuation and a
4494       value > 1.0 means amplification).  This parameter easily allows to
4495       adjust the volume of all intruments within a custom instrument map
4496       without having to adjust their instrument files.  The OPTIONAL
4497       <instr_load_mode> argument defines the life time of the instrument,
4498       that is when the instrument should be loaded, when freed and has
4499       exactly the following possibilities:
4500    
4501          "ON_DEMAND" -
4502    
4503             The instrument will be loaded when needed, that is when
4504             demanded by at least one sampler channel.  It will immediately
4505             be freed from memory when not needed by any sampler channel
4506             anymore.
4507    
4508          "ON_DEMAND_HOLD" -
4509    
4510             The instrument will be loaded when needed, that is when
4511             demanded by at least one sampler channel.  It will be kept in
4512             memory even when not needed by any sampler channel anymore.
4513             Instruments with this mode are only freed when the sampler is
4514             reset or all mapping entries with this mode (and respective
4515             instrument) are explicitly changed to "ON_DEMAND" and no
4516             sampler channel is using the instrument anymore.
4517    
4518          "PERSISTENT" -
4519    
4520             The instrument will immediately be loaded into memory when this
4521             mapping command is sent and the instrument is kept all the
4522             time.  Instruments with this mode are only freed when the
4523             sampler is reset or all mapping entries with this mode (and
4524             respective instrument) are explicitly changed to "ON_DEMAND"
4525             and no sampler channel is using the instrument anymore.
4526    
4527          not supplied -
4528    
4529             In case there is no <instr_load_mode> argument given, it will
4530             be up to the InstrumentManager to decide which mode to use.
4531             Usually it will use "ON_DEMAND" if an entry for the given
4532    
4533

4538    
4539    
4540             instrument does not exist in the InstrumentManager's list yet,
4541             otherwise if an entry already exists, it will simply stick with
4542             the mode currently reflected by the already existing entry,
4543             that is it will not change the mode.
4544    
4545       The <instr_load_mode> argument thus allows to define an appropriate
4546       strategy (low memory consumption vs. fast instrument switching) for
4547       each instrument individually.  Note, the following restrictions apply
4548       to this argument: "ON_DEMAND_HOLD" and "PERSISTENT" have to be
4549       supported by the respective sampler engine (which is technically the
4550       case when the engine provides an InstrumentManager for its format).
4551       If this is not the case the argument will automatically fall back to
4552       the default value "ON_DEMAND".  Also the load mode of one instrument
4553       may automatically change the laod mode of other instrument(s), i.e.
4554       because the instruments are part of the same file and the engine does
4555       not allow a way to manage load modes for them individually.  Due to
4556       this, in case the frontend shows the load modes of entries, the
4557       frontend should retrieve the actual mode by i.e. sending "GET
4558       MIDI_INSTRUMENT INFO" (Section 6.7.11) command(s).  Finally the
4559       OPTIONAL <name> argument allows to set a custom name (encapsulated
4560       into apostrophes, supporting escape sequences as described in chapter
4561       "Character Set and Escape Sequences (Section 7.1)") for the mapping
4562       entry, useful for frontends for displaying an appropriate name for
4563       mapped instruments (using "GET MIDI_INSTRUMENT INFO"
4564       (Section 6.7.11)).
4565    
4566       By default, "MAP MIDI_INSTRUMENT" commands block until the mapping is
4567       completely established in the sampler.  The OPTIONAL "NON_MODAL"
4568       argument however causes the respective "MAP MIDI_INSTRUMENT" command
4569       to return immediately, that is to let the sampler establish the
4570       mapping in the background.  So this argument might be especially
4571       useful for mappings with a "PERSISTENT" type, because these have to
4572       load the respective instruments immediately and might thus block for
4573       a very long time.  It is recommended however to use the OPTIONAL
4574       "NON_MODAL" argument only if really necessary, because it has the
4575       following drawbacks: as "NON_MODAL" instructions return immediately,
4576       they may not necessarily return an error i.e. when the given
4577       instrument file turns out to be corrupt, beside that subsequent
4578       commands in a LSCP instruction sequence might fail, because mandatory
4579       mappings are not yet completed.

5234       not be searched. <criteria-list> is a list of search criterias in
5235       form of "key1=val1 key2=val2 ...".  The following criterias are
5236       allowed:
5237    
5238       NAME='<search-string>'
5239    
5240          Restricts the search to directories, which names satisfy the

5309          [<instr_index>]
5310    
5311       Where <db_dir> is the absolute path name of a directory (encapsulated
5312       into apostrophes) in the instruments database in which only the new
5313       instruments (that are not already in the database) will be added,
5314       <file_path> is the absolute path name of a file or directory in the
5315       file system (encapsulated into apostrophes).  In case an instrument

5322    
5323    
5324       file is supplied, only the instruments in the specified file will be
5325       added to the instruments database.  If the optional <instr_index>
5326       (the index of the instrument within the given file) is supplied too,
5327       then only the specified instrument will be added.  In case a
5328       directory is supplied, the instruments in that directory will be
5329       added.  The OPTIONAL <mode> argument is only applied when a directory
5330       is provided as <file_path> and specifies how the scanning will be
5331       done and has exactly the following possibilities:
5332    
5333          "RECURSIVE" -
5334    
5335             All instruments will be processed, including those in the
5336             subdirectories, and the respective subdirectory tree structure
5337             will be recreated in the instruments database
5338    
5339          "NON_RECURSIVE" -
5340    
5341             Only the instruments in the specified directory will be added,
5342             the instruments in the subdirectories will not be processed.
5343    
5344          "FLAT" -
5345    
5346             All instruments will be processed, including those in the
5347             subdirectories, but the respective subdirectory structure will
5348             not be recreated in the instruments database.  All instruments
5349             will be added directly in the specified database directory.
5350    
5351       The difference between regular and NON_MODAL versions of the command
5352       is that the regular command returns when the scanning is finished
5353       while NON_MODAL version returns immediately and a background process
5354       is launched.  The GET DB_INSTRUMENTS_JOB INFO (Section 6.8.21)
5355       command can be used to monitor the scanning progress.
5356    
5357       Possible Answers:
5358    
5359          "OK" -

5415    6.8.13.  Getting amount of instruments
5416    
5417       The front-end can retrieve the current amount of instruments in a
5418       specific directory by sending the following command:
5419    
5420          GET DB_INSTRUMENTS [RECURSIVE] <dir>

5955    
5956       The front-end can remove all instruments and directories and re-
5957       create the instruments database structure (e.g., in case of a
5958       database corruption) by sending the following command:
5959    
5960          FORMAT INSTRUMENTS_DB
5961    
5962       Possible Answers:
5963    
5964          "OK" -
5965    
5966             on success
5967    
5968          "ERR:<error-code>:<error-message>" -
5969    
5970             If the formatting of the instruments database failed.
5971    
5972    6.9.  Editing Instruments
5973    
5974       The sampler allows to edit instruments while playing with the sampler
5975       by spawning an external (3rd party) instrument editor application for
5976       a given instrument.  The 3rd party instrument editor applications
5977       have to place a respective plugin DLL file into the sampler's plugins
5978       directory.  The sampler will automatically try to load all plugin
5979       DLLs in that directory on startup and only on startup!
5980    
5981       At the moment there is only one command for this feature set, but
5982       this will most probably change in future.
5983    
5984    6.9.1.  Opening an appropriate instrument editor application
5985    
5986       The front-end can request to open an appropriate instrument editor
5987       application by sending the following command:
5988    
5989

5994    
5995    
5996          EDIT CHANNEL INSTRUMENT <sampler-channel>
5997    
5998       Where <sampler-channel> should be replaced by the number of the
5999       sampler channel as given by the "ADD CHANNEL" (Section 6.4.5) or
6000       "LIST CHANNELS" (Section 6.4.4) command.
6001    
6002       The sampler will try to ask all registered instrument editors (or to
6003       be more specific: their sampler plugins) whether they are capable to
6004       handle the instrument on the given sampler channel.  The sampler will
6005       simply use the first instrument editor application which replied with
6006       a positive answer and spawn that instrument editor application within
6007       the sampler's process and provide that application access to the
6008       instrument's data structures, so both applications can share and
6009       access the same instruments data at the same time, thus allowing to
6010       immediately hear changes with the sampler made by the instrument
6011       editor.
6012    
6013       Note: consequently instrument editors are always spawned locally on
6014       the same machine where the sampler is running on!
6015    
6016       Possible Answers:
6017    
6018          "OK" -
6019    
6020             when an appropriate instrument editor was launched
6021    
6022          "WRN:<warning-code>:<warning-message>" -
6023    
6024             when an appropriate instrument editor was launched, but there
6025             are noteworthy issues
6026    
6027          "ERR:<error-code>:<error-message>" -
6028    
6029             when an appropriate instrument editor could not be launched
6030

6034    
6035          S: "OK"
6036    
6037    6.10.  Managing Files
6038    
6039       You can query detailed informations about files located at the same
6040       system where the sampler instance is running on.  Using this command
6041       set allows to retrieve file informations even remotely from another
6042       machine.

6052    6.10.1.  Retrieving amount of instruments of a file
6053    
6054       The front-end can retrieve the amount of instruments within a given
6055       instrument file by sending the following command:
6056    
6057          GET FILE INSTRUMENTS <filename>
6058    
6059       Where <filename> is the name of the instrument file (encapsulated
6060       into apostrophes, supporting escape sequences as described in chapter
6061       "Character Set and Escape Sequences (Section 7.1)").
6062    
6063       The sampler will try to ask all sampler engines, whether they support
6064       the given file and ask the first engine with a positive answer for
6065       the amount of instruments.
6066    
6067       Possible Answers:
6068    
6069          On success, the sampler will answer by returning the amount of
6070          instruments.

6082    6.10.2.  Retrieving all instruments of a file
6083    
6084       The front-end can retrieve a list of all instruments within a given
6085       instrument file by sending the following command:
6086    
6087          LIST FILE INSTRUMENTS <filename>
6088    
6089       Where <filename> is the name of the instrument file (encapsulated
6090       into apostrophes, supporting escape sequences as described in chapter
6091       "Character Set and Escape Sequences (Section 7.1)").
6092    
6093       The sampler will try to ask all sampler engines, whether they support
6094       the given file and ask the first engine with a positive answer for a
6095       list of IDs for the instruments in the given file.
6096

6106    
6107    
6108          On success, the sampler will answer by returning a comma separated
6109          list of instrument IDs.
6110    
6111          "ERR:<error-code>:<error-message>" -
6112    
6113             if the file could not be handled
6114    
6115       Examples:
6116    
6117          C: "LIST FILE INSTRUMENTS 'D:/Sounds/Foo.gig'"
6118    
6119          S: "0,1,2,3,4,5,6,7,8,9"
6120    
6121    6.10.3.  Retrieving informations about one instrument in a file
6122    
6123       The front-end can retrieve detailed informations about a specific
6124       instrument within a given instrument file by sending the following
6125       command:
6126    
6127          GET FILE INSTRUMENT INFO <filename> <instr-id>
6128    
6129       Where <filename> is the name of the instrument file (encapsulated
6130       into apostrophes, supporting escape sequences as described in chapter
6131       "Character Set and Escape Sequences (Section 7.1)") and <instr-id> is
6132       the numeric instrument ID as returned by the "LIST FILE INSTRUMENTS"
6133       (Section 6.10.2) command.
6134    
6135       The sampler will try to ask all sampler engines, whether they support
6136       the given file and ask the first engine with a positive answer for
6137       informations about the specific instrument in the given file.
6138    
6139       Possible Answers:
6140    
6141          LinuxSampler will answer by sending a <CRLF> separated list.  Each
6142          answer line begins with the settings category name followed by a
6143          colon and then a space character <SP> and finally the info
6144          character string to that setting category.  At the moment the
6145          following categories are defined:
6146    
6147

7034    
7035       Notice: due to the transition of certain parts of the protocol which
7036       now support escape sequences, a slight backward incompatibility to
7037       protocols version v1.1 and younger has been introduced.  The only
7038       difference is that in parts of the protocol where escape characters
7039       are now supported, a backslash characters MUST be escaped as well
7040       (that is as double backslash), whereas in the old versions a single
7041       backslash was sufficient.
7042    
7043       The following LSCP commands support escape sequences as part of their
7044       filename / path based arguments and / or may contain a filename /
7045       path with escape sequences in their response:

7117    
7118       Note that the forward slash character ('/') has a special meaning in
7119       filename / path based arguments: it acts as separator of the nodes in
7120       the path, thus if a directory- or filename includes a forward slash
7121       (not intended as path node separator), you MUST escape that slash
7122       either with the respective hex escape sequence ("\x2f") or with the
7123       respective octal escape sequence ("\057").
7124    
7125       Note for Windows: file path arguments in LSCP are expected to use
7126       forward slashes as directory node separator similar to Unix based
7127       operating systems.  In contrast to Unix however a Windows typical
7128       drive character is expected to be prefixed to the path.  That is an
7129       original Windows file path like "D:\Sounds\My.gig" would become in
7130       LSCP: "D:/Sounds/My.gig".
7131    
7132       The following LSCP commands even support escape sequences as part of
7133       at least one of their text-based arguments (i.e. entity name,
7134       description) and / or may contain escape sequences in at least one of
7135       their text-based fields in their response:

7620       directory info.  Because these messages will be triggered by LSCP
7621       commands issued by other clients rather than real time events
7622       happening on the server, it is believed that an empty notification
7623       message is sufficient here.
7624    
7625          "NOTIFY:DB_INSTRUMENT_DIRECTORY_INFO:NAME <old-dir-path> <new-
7626          name>"
7627    
7628       where <old-dir-path> is the old absolute path name of the directory
7629       (encapsulated into apostrophes), which name is changes and <new-name>
7630       is the new name of the directory, encapsulated into apostrophes.
7631    
7632    8.21.  Number of database instruments changed
7633    
7634       Client may want to be notified when the number of instruments in a
7635       particular directory in the instruments database is changed by
7636       issuing the following command:
7637    
7638          SUBSCRIBE DB_INSTRUMENT_COUNT
7639    
7640       Server will start sending the following notification messages:
7641    
7642          "NOTIFY:DB_INSTRUMENT_COUNT:<dir-path>"
7643    
7644       where <dir-path> will be replaced by the absolute path name of the
7645       directory in the instruments database, in which the number of
7646       instruments is changed.
7647    
7648       Note that when a non-empty directory is removed, this event is not
7649       sent for the instruments in that directory.
7650    
7651    8.22.  Database instrument information changed
7652    
7653       Client may want to be notified when changes were made to instruments
7654       in the instruments database by issuing the following command:
7655    
7656          SUBSCRIBE DB_INSTRUMENT_INFO
7657    
7658       Server will start sending the following notification messages:
7659    
7660          "NOTIFY:DB_INSTRUMENT_INFO:<instr-path>"
7661    
7662       where <instr-path> will be replaced by the absolute path name of the
7663       instrument, which settings are changed.  The front-end will have to
7664       send the respective command to actually get the updated directory
7665       info.  Because these messages will be triggered by LSCP commands
7666       issued by other clients rather than real time events happening on the
7667       server, it is believed that an empty notification message is
7668

7677    
7678          "NOTIFY:DB_INSTRUMENT_INFO:NAME <old-instr-path> <new-name>"
7679    
7680       where <old-instr-path> is the old absolute path name of the
7681       instrument (encapsulated into apostrophes), which name is changes and
7682       <new-name> is the new name of the instrument, encapsulated into
7683       apostrophes.
7684    
7685    8.23.  Database job status information changed
7686    
7687       Client may want to be notified when the status of particular database
7688       instruments job is changed by issuing the following command:
7689    
7690          SUBSCRIBE DB_INSTRUMENTS_JOB_INFO
7691    
7692       Server will start sending the following notification messages:
7693    
7694          "NOTIFY:DB_INSTRUMENTS_JOB_INFO:<job-id>"
7695    
7696       where <job-id> will be replaced by the numerical ID of the job, which
7697       status is changed.  The front-end will have to send the respective
7698       command to actually get the status info.  Because these messages will
7699       be triggered by LSCP commands issued by other clients rather than
7700       real time events happening on the server, it is believed that an
7701       empty notification message is sufficient here.
7702    
7703    8.24.  Miscellaneous and debugging events
7704    
7705       Client may want to be notified of miscellaneous and debugging events
7706       occurring at the server by issuing the following command:
7707    
7708          SUBSCRIBE MISCELLANEOUS
7709    
7710       Server will start sending the following notification messages:
7711    
7712          "NOTIFY:MISCELLANEOUS:<string>"
7713    
7714       where <string> will be replaced by whatever data server wants to send
7715       to the client.  Client MAY display this data to the user AS IS to
7716       facilitate debugging.
