3890    
3891       The front-end can send MIDI events to specific sampler channel by
3892       sending the following command:
3893    
3894          SEND CHANNEL MIDI_DATA <midi-msg> <sampler-chan> <arg1> <arg2>
3895

3897       "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4)
3898       command, <arg1> and <arg2> arguments depend on the <midi-msg>
3899       argument, which specifies the MIDI message type.  Currently, the
3900       following MIDI messages are supported:
3901    
3902          "NOTE_ON" -
3903    
3904             For turning on MIDI notes, where <arg1> specifies the key
3905             number and <arg2> the velocity as described in the MIDI
3906             specification.
3907    
3908          "NOTE_OFF" -
3909    
3910             For turning a currently playing MIDI note off, where <arg1>
3911             specifies the key number and <arg2> the velocity as described
3912             in the MIDI specification.
3913    
3914       CAUTION: This command is provided for implementations of virtual MIDI

6091    6.9.  Editing Instruments
6092    
6093       The sampler allows to edit instruments while playing with the sampler
6094       by spawning an external (3rd party) instrument editor application for
6095       a given instrument.  The 3rd party instrument editor applications
6096       have to place a respective plugin DLL file into the sampler's plugins
6097       directory.  The sampler will automatically try to load all plugin
6098       DLLs in that directory on startup and only on startup!

6108       At the moment there is only one command for this feature set, but
6109       this will most probably change in future.
6110    
6111    6.9.1.  Opening an appropriate instrument editor application
6112    
6113       The front-end can request to open an appropriate instrument editor
6114       application by sending the following command:
6115    
6116          EDIT CHANNEL INSTRUMENT <sampler-channel>
6117    
6118       Where <sampler-channel> should be replaced by the number of the
6119       sampler channel as given by the "ADD CHANNEL" (Section 6.4.5) or
6120       "LIST CHANNELS" (Section 6.4.4) command.
6121    
6122       The sampler will try to ask all registered instrument editors (or to
6123       be more specific: their sampler plugins) whether they are capable to
6124       handle the instrument on the given sampler channel.  The sampler will
6125       simply use the first instrument editor application which replied with
6126       a positive answer and spawn that instrument editor application within
6127       the sampler's process and provide that application access to the
6128       instrument's data structures, so both applications can share and
6129       access the same instruments data at the same time, thus allowing to
6130       immediately hear changes with the sampler made by the instrument
6131       editor.
6132    
6133       Note: consequently instrument editors are always spawned locally on
6134       the same machine where the sampler is running on!

6166    6.10.  Managing Files
6167    
6168       You can query detailed informations about files located at the same
6169       system where the sampler instance is running on.  Using this command
6170       set allows to retrieve file informations even remotely from another
6171       machine.
6172    
6173    6.10.1.  Retrieving amount of instruments of a file
6174    
6175       The front-end can retrieve the amount of instruments within a given
6176       instrument file by sending the following command:
6177    
6178          GET FILE INSTRUMENTS <filename>
6179    
6180       Where <filename> is the name of the instrument file (encapsulated
6181       into apostrophes, supporting escape sequences as described in chapter
6182       "Character Set and Escape Sequences (Section 7.1)").
6183    
6184       The sampler will try to ask all sampler engines, whether they support
6185       the given file and ask the first engine with a positive answer for
6186       the amount of instruments.
6187    
6188       Possible Answers:
6189    
6190          On success, the sampler will answer by returning the amount of
6191          instruments.
6192    
6193          "ERR:<error-code>:<error-message>" -
6194    
6195             if the file could not be handled
6196    
6197       Examples:
6198    
6199          C: "GET FILE INSTRUMENTS 'D:/Sounds/Foo.gig'"
6200    
6201          S: "10"
6202    
6203    6.10.2.  Retrieving all instruments of a file
6204    
6205       The front-end can retrieve a list of all instruments within a given
6206       instrument file by sending the following command:
6207    
6208          LIST FILE INSTRUMENTS <filename>
6209    
6210       Where <filename> is the name of the instrument file (encapsulated
6211       into apostrophes, supporting escape sequences as described in chapter
6212

6221    
6222       The sampler will try to ask all sampler engines, whether they support
6223       the given file and ask the first engine with a positive answer for a
6224       list of IDs for the instruments in the given file.
6225    
6226       Possible Answers:
6227    
6228          On success, the sampler will answer by returning a comma separated
6229          list of instrument IDs.
6230    
6231          "ERR:<error-code>:<error-message>" -
6232    
6233             if the file could not be handled
6234    
6235       Examples:
6236    
6237          C: "LIST FILE INSTRUMENTS 'D:/Sounds/Foo.gig'"
6238    
6239          S: "0,1,2,3,4,5,6,7,8,9"
6240    
6241    6.10.3.  Retrieving informations about one instrument in a file
6242    
6243       The front-end can retrieve detailed informations about a specific
6244       instrument within a given instrument file by sending the following
6245       command:
6246    
6247          GET FILE INSTRUMENT INFO <filename> <instr-id>
6248    
6249       Where <filename> is the name of the instrument file (encapsulated
6250       into apostrophes, supporting escape sequences as described in chapter
6251       "Character Set and Escape Sequences (Section 7.1)") and <instr-id> is
6252       the numeric instrument ID as returned by the "LIST FILE INSTRUMENTS"
6253       (Section 6.10.2) command.
6254    
6255       The sampler will try to ask all sampler engines, whether they support
6256       the given file and ask the first engine with a positive answer for
6257       informations about the specific instrument in the given file.
6258    
6259       Possible Answers:
6260    
6261          LinuxSampler will answer by sending a <CRLF> separated list.  Each
6262          answer line begins with the settings category name followed by a
6263          colon and then a space character <SP> and finally the info
6264          character string to that setting category.  At the moment the
6265          following categories are defined:

7309    
7310       Note that the forward slash character ('/') has a special meaning in
7311       filename / path based arguments: it acts as separator of the nodes in
7312       the path, thus if a directory- or filename includes a forward slash
7313       (not intended as path node separator), you MUST escape that slash
7314       either with the respective hex escape sequence ("\x2f") or with the
7315       respective octal escape sequence ("\057").
7316    
7317       Note for Windows: file path arguments in LSCP are expected to use
7318       forward slashes as directory node separator similar to Unix based
7319       operating systems.  In contrast to Unix however a Windows typical
7320       drive character is expected to be prefixed to the path.  That is an
7321       original Windows file path like "D:\Sounds\My.gig" would become in
7322       LSCP: "D:/Sounds/My.gig".
7323    
7324       The following LSCP commands even support escape sequences as part of
7325       at least one of their text-based arguments (i.e. entity name,
7326       description) and / or may contain escape sequences in at least one of
7327       their text-based fields in their response:
