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.

6035    6.9.  Editing Instruments
6036    
6037       The sampler allows to edit instruments while playing with the sampler
6038       by spawning an external (3rd party) instrument editor application for
6039       a given instrument.  The 3rd party instrument editor applications
6040       have to place a respective plugin DLL file into the sampler's plugins
6041       directory.  The sampler will automatically try to load all plugin
6042       DLLs in that directory on startup and only on startup!

6050    
6051    
6052       At the moment there is only one command for this feature set, but
6053       this will most probably change in future.
6054    
6055    6.9.1.  Opening an appropriate instrument editor application
6056    
6057       The front-end can request to open an appropriate instrument editor
6058       application by sending the following command:
6059    
6060          EDIT CHANNEL INSTRUMENT <sampler-channel>
6061    
6062       Where <sampler-channel> should be replaced by the number of the
6063       sampler channel as given by the "ADD CHANNEL" (Section 6.4.5) or
6064       "LIST CHANNELS" (Section 6.4.4) command.
6065    
6066       The sampler will try to ask all registered instrument editors (or to
6067       be more specific: their sampler plugins) whether they are capable to
6068       handle the instrument on the given sampler channel.  The sampler will
6069       simply use the first instrument editor application which replied with
6070       a positive answer and spawn that instrument editor application within
6071       the sampler's process and provide that application access to the
6072       instrument's data structures, so both applications can share and
6073       access the same instruments data at the same time, thus allowing to
6074       immediately hear changes with the sampler made by the instrument
6075       editor.
6076    
6077       Note: consequently instrument editors are always spawned locally on
6078       the same machine where the sampler is running on!
6079    
6080       Possible Answers:
6081    
6082          "OK" -

6085    
6086          "WRN:<warning-code>:<warning-message>" -
6087    
6088             when an appropriate instrument editor was launched, but there
6089             are noteworthy issues
6090    
6091          "ERR:<error-code>:<error-message>" -

6110    6.10.  Managing Files
6111    
6112       You can query detailed informations about files located at the same
6113       system where the sampler instance is running on.  Using this command
6114       set allows to retrieve file informations even remotely from another
6115       machine.
6116    
6117    6.10.1.  Retrieving amount of instruments of a file
6118    
6119       The front-end can retrieve the amount of instruments within a given
6120       instrument file by sending the following command:
6121    
6122          GET FILE INSTRUMENTS <filename>
6123    
6124       Where <filename> is the name of the instrument file (encapsulated
6125       into apostrophes, supporting escape sequences as described in chapter
6126       "Character Set and Escape Sequences (Section 7.1)").
6127    
6128       The sampler will try to ask all sampler engines, whether they support
6129       the given file and ask the first engine with a positive answer for
6130       the amount of instruments.
6131    
6132       Possible Answers:
6133    
6134          On success, the sampler will answer by returning the amount of
6135          instruments.
6136    
6137          "ERR:<error-code>:<error-message>" -
6138    
6139             if the file could not be handled
6140    
6141       Examples:
6142

6144    
6145          S: "10"
6146    
6147    6.10.2.  Retrieving all instruments of a file
6148    
6149       The front-end can retrieve a list of all instruments within a given
6150       instrument file by sending the following command:
6151    
6152          LIST FILE INSTRUMENTS <filename>

6165    
6166       The sampler will try to ask all sampler engines, whether they support
6167       the given file and ask the first engine with a positive answer for a
6168       list of IDs for the instruments in the given file.
6169    
6170       Possible Answers:
6171    
6172          On success, the sampler will answer by returning a comma separated
6173          list of instrument IDs.
6174    
6175          "ERR:<error-code>:<error-message>" -
6176    
6177             if the file could not be handled
6178    
6179       Examples:
6180    
6181          C: "LIST FILE INSTRUMENTS 'D:/Sounds/Foo.gig'"
6182

6185    6.10.3.  Retrieving informations about one instrument in a file
6186    
6187       The front-end can retrieve detailed informations about a specific
6188       instrument within a given instrument file by sending the following
6189       command:
6190    
6191          GET FILE INSTRUMENT INFO <filename> <instr-id>
6192    
6193       Where <filename> is the name of the instrument file (encapsulated
6194       into apostrophes, supporting escape sequences as described in chapter
6195       "Character Set and Escape Sequences (Section 7.1)") and <instr-id> is
6196       the numeric instrument ID as returned by the "LIST FILE INSTRUMENTS"
6197       (Section 6.10.2) command.
6198    
6199       The sampler will try to ask all sampler engines, whether they support
6200       the given file and ask the first engine with a positive answer for
6201       informations about the specific instrument in the given file.
6202    
6203       Possible Answers:
6204    
6205          LinuxSampler will answer by sending a <CRLF> separated list.  Each
6206          answer line begins with the settings category name followed by a
6207          colon and then a space character <SP> and finally the info
6208          character string to that setting category.  At the moment the
6209          following categories are defined:

7068    7.1.  Character Set and Escape Sequences
7069    
7070       Older versions of this protocol up to and including v1.1 only
7071       supported the standard ASCII character set (ASCII code 0 - 127)
7072       [RFC20], all younger versions of this protocol however support the
7073       Extended ASCII character set (ASCII code 0 - 255).  The same group of
7074       younger protocols also support escape sequences, but only for
7075       certain, explicitly declared parts of the protocol.  The supported
7076       escape sequences are defined as follows:
7077    
7078       +------------------------+------------------------------------------+
7079       | ASCII Character        | Translated into (Name)                   |

7102       |                        | character                                |
7103       +------------------------+------------------------------------------+
7104    
7105       Notice: due to the transition of certain parts of the protocol which
7106       now support escape sequences, a slight backward incompatibility to
7107       protocols version v1.1 and younger has been introduced.  The only

7113    Internet-Draft        LinuxSampler Control Protocol           April 2008
7114    
7115    
7116       difference is that in parts of the protocol where escape characters
7117       are now supported, a backslash characters MUST be escaped as well
7118       (that is as double backslash), whereas in the old versions a single
7119       backslash was sufficient.
7120    
7121       The following LSCP commands support escape sequences as part of their
7122       filename / path based arguments and / or may contain a filename /
7123       path with escape sequences in their response:

7191    
7192       Note that the forward slash character ('/') has a special meaning in
7193       filename / path based arguments: it acts as separator of the nodes in
7194       the path, thus if a directory- or filename includes a forward slash
7195       (not intended as path node separator), you MUST escape that slash
7196       either with the respective hex escape sequence ("\x2f") or with the
7197       respective octal escape sequence ("\057").
7198    
7199       Note for Windows: file path arguments in LSCP are expected to use
7200       forward slashes as directory node separator similar to Unix based
7201       operating systems.  In contrast to Unix however a Windows typical
7202       drive character is expected to be prefixed to the path.  That is an
7203       original Windows file path like "D:\Sounds\My.gig" would become in
7204       LSCP: "D:/Sounds/My.gig".
7205    
7206       The following LSCP commands even support escape sequences as part of
7207       at least one of their text-based arguments (i.e. entity name,
7208       description) and / or may contain escape sequences in at least one of
