4824    6.8.  Managing Instruments Database
4825    
4826       The following commands describe how to use and manage the instruments
4827       database.
4828    
4829       Notice:
4830    
4831          All command arguments representing a path or instrument/directory
4832          name support escape sequences as described in chapter "Character
4833          Set and Escape Sequences (Section 7.1)".
4834    
4835          All occurrences of a forward slash in instrument and directory
4836          names are escaped with its hex (\x2f) or octal (\057) escape
4837          sequence.
4838    
4839    6.8.1.  Creating a new instrument directory
4840    
4841       The front-end can add a new instrument directory to the instruments
4842       database by sending the following command:
4843    
4844          ADD DB_INSTRUMENT_DIRECTORY <dir>
4845    
4846       Where <dir> is the absolute path name of the directory to be created
4847       (encapsulated into apostrophes).
4848    
4849       Possible Answers:
4850    
4851          "OK" -
4852    
4853             on success
4854    
4855          "ERR:<error-code>:<error-message>" -
4856    
4857             when the directory could not be created, which can happen if
4858             the directory already exists or the name contains not allowed
4859             symbols
4860    
4861       Examples:
4862

4876    6.8.2.  Deleting an instrument directory
4877    
4878       The front-end can delete a particular instrument directory from the
4879       instruments database by sending the following command:
4880    
4881          REMOVE DB_INSTRUMENT_DIRECTORY [FORCE] <dir>
4882    
4883       Where <dir> is the absolute path name of the directory to delete.
4884       The optional FORCE argument can be used to force the deletion of a
4885       non-empty directory and all its content.
4886    
4887       Possible Answers:
4888    
4889          "OK" -
4890    
4891             if the directory is deleted successfully
4892    
4893          "ERR:<error-code>:<error-message>" -
4894    
4895             if the given directory does not exist, or if trying to delete a
4896             non-empty directory, without using the FORCE argument.
4897    
4898       Examples:
4899

5268       into apostrophes) in the instruments database in which only the new
5269       instruments (that are not already in the database) will be added,
5270       <file_path> is the absolute path name of a file or directory in the
5271       file system (encapsulated into apostrophes).  In case an instrument
5272       file is supplied, only the instruments in the specified file will be
5273       added to the instruments database.  If the optional <instr_index>
5274       (the index of the instrument within the given file) is supplied too,
5275       then only the specified instrument will be added.  In case a
5276       directory is supplied, the instruments in that directory will be
5277       added.  The OPTIONAL <mode> argument is only applied when a directory
5278       is provided as <file_path> and specifies how the scanning will be
5279       done and has exactly the following possibilities:
5280    
5281          "RECURSIVE" -
5282    
5283             All instruments will be processed, including those in the
5284             subdirectories, and the respective subdirectory tree structure
5285             will be recreated in the instruments database
5286    
5287          "NON_RECURSIVE" -
5288    
5289             Only the instruments in the specified directory will be added,
5290             the instruments in the subdirectories will not be processed.
5291    
5292          "FLAT" -
5293    
5294             All instruments will be processed, including those in the
5295             subdirectories, but the respective subdirectory structure will
5296             not be recreated in the instruments database.  All instruments
5297             will be added directly in the specified database directory.
5298    
5299       The difference between regular and NON_MODAL versions of the command
5300       is that the regular command returns when the scanning is finished
5301       while NON_MODAL version returns immediately and a background process
5302       is launched.  The GET DB_INSTRUMENTS_JOB INFO (Section 6.8.21)
5303       command can be used to monitor the scanning progress.

5307          "OK" -
5308    
5309             on success when NON_MODAL is not supplied
5310    
5311          "OK[<job-id>]" -
5312    
5313             on success when NON_MODAL is supplied, where <job-id> is a
5314             numerical ID used to obtain status information about the job
5315             progress.  See GET DB_INSTRUMENTS_JOB INFO (Section 6.8.21)

5883    
5884       Example:
5885    
5886          C: "GET DB_INSTRUMENTS_JOB INFO 2"
5887    
5888          S: "FILES_TOTAL: 12"
5889    
5890             "FILES_SCANNED: 7"
5891    
5892             "SCANNING: /home/me/gigs/Bosendorfer 290.gig"
5893    
5894             "STATUS: 42"
5895    
5896             "."
5897    
5898    6.8.22.  Formatting the instruments database
5899    
5900       The front-end can remove all instruments and directories and re-
5901       create the instruments database structure (e.g., in case of a
5902       database corruption) by sending the following command:
5903    
5904          FORMAT INSTRUMENTS_DB
5905    
5906       Possible Answers:
5907    
5908          "OK" -
5909    
5910             on success
5911    
5912          "ERR:<error-code>:<error-message>" -
5913    
5914             If the formatting of the instruments database failed.
5915    
5916    6.9.  Editing Instruments
5917    
5918       The sampler allows to edit instruments while playing with the sampler
5919       by spawning an external (3rd party) instrument editor application for
5920       a given instrument.  The 3rd party instrument editor applications
5921       have to place a respective plugin DLL file into the sampler's plugins
5922       directory.  The sampler will automatically try to load all plugin
5923       DLLs in that directory on startup and only on startup!
5924    
5925       At the moment there is only one command for this feature set, but
5926       this will most probably change in future.
5927    
5928    6.9.1.  Opening an appropriate instrument editor application
5929    
5930       The front-end can request to open an appropriate instrument editor
5931       application by sending the following command:
5932    
5933    
5934

5937    Internet-Draft    LinuxSampler Control Protocol (draft)   September 2007
5938    
5939    
5940          EDIT INSTRUMENT <sampler-channel>
5941    
5942       Where <sampler-channel> should be replaced by the number of the
5943       sampler channel as given by the "ADD CHANNEL" (Section 6.4.5) or
5944       "LIST CHANNELS" (Section 6.4.4) command.
5945    
5946       The sampler will try to ask all registered instrument editors (or to
5947       be more specific: their sampler plugins) whether they are capable to
5948       handle the instrument on the given sampler channel.  The sampler will
5949       simply use the first instrument editor application which replied with
5950       a positive answer and spawn that instrument editor application within
5951       the sampler's process and provide that application access to the
5952       instrument's data structures, so both applications can share and
5953       access the same instruments data at the same time, thus allowing to
5954       immediately hear changes with the sampler made by the instrument
5955       editor.
5956    
5957       Note: consequently instrument editors are always spawned locally on
5958       the same machine where the sampler is running on!
5959    
5960       Possible Answers:
5961    
5962          "OK" -
5963    
5964             when an appropriate instrument editor was launched
5965    
5966          "WRN:<warning-code>:<warning-message>" -
5967    
5968             when an appropriate instrument editor was launched, but there
5969             are noteworthy issues
5970    
5971          "ERR:<error-code>:<error-message>" -
5972    
5973             when an appropriate instrument editor could not be launched
5974    
5975       Examples:
5976    
5977          C: "EDIT INSTRUMENT 0"
5978

6758    7.1.  Character Set and Escape Sequences
6759    
6760       Older versions of this protocol up to and including v1.1 only
6761       supported the standard ASCII character set (ASCII code 0 - 127)
6762       [RFC20], all younger versions of this protocol however support the
6763       Extended ASCII character set (ASCII code 0 - 255).  The same group of
6764       younger protocols also support escape sequences, but only for
6765       certain, explicitly declared parts of the protocol.  The supported
6766       escape sequences are defined as follows:

6805       +------------------------+------------------------------------------+
6806    
6807       Notice: due to the transition of certain parts of the protocol which
6808       now support escape sequences, a slight backward incompatibility to
6809       protocols version v1.1 and younger has been introduced.  The only
6810       difference is that in parts of the protocol where escape characters
6811       are now supported, a backslash characters MUST be escaped as well
6812       (that is as double backslash), whereas in the old versions a single
6813       backslash was sufficient.
