5957       create the instruments database structure (e.g., in case of a
5958       database corruption) by sending the following command:

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:

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!

6055       instrument file by sending the following command:
6056    
6057          GET FILE INSTRUMENTS <filename>

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:

6088    
6089       Where <filename> is the name of the instrument file (encapsulated

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.

6128    
6129       Where <filename> is the name of the instrument file (encapsulated

7125    
7126       Note that the forward slash character ('/') has a special meaning in
7127       filename / path based arguments: it acts as separator of the nodes in
7128       the path, thus if a directory- or filename includes a forward slash
7129       (not intended as path node separator), you MUST escape that slash
7130       either with the respective hex escape sequence ("\x2f") or with the
7131       respective octal escape sequence ("\057").
7132    
7133       Note for Windows: file path arguments in LSCP are expected to use
7134       forward slashes as directory node separator similar to Unix based
7135       operating systems.  In contrast to Unix however a Windows typical
7136       drive character is expected to be prefixed to the path.  That is an
7137       original Windows file path like "D:\Sounds\My.gig" would become in
7138       LSCP: "D:/Sounds/My.gig".
7139    
7140       The following LSCP commands even support escape sequences as part of
7141       at least one of their text-based arguments (i.e. entity name,
