3442  Schoenebeck               Expires June 23, 2007                [Page 60]  6.4.25.  Adding an effect send to a sampler channel
3443    
3444       The front-end can create an additional effect send on a specific
3445       sampler channel by sending the following command:
3446    
3447          CREATE FX_SEND <sampler-channel> <midi-ctrl> [<name>]
3448    
3449       Where <sampler-channel> is the respective sampler channel number as
3450       returned by the "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS"
3451       (Section 6.4.4) command, that is the sampler channel on which the
3452       effect send should be created on, <midi-ctrl> is a number between
3453       0..127 defining the MIDI controller which can alter the effect send
3454       level and <name> is an optional argument defining a name for the
3455       effect send entity.  The name does not have to be unique, but MUST be
3456       encapsulated into apostrophes and supports escape sequences as
3457       described in chapter "Character Set and Escape Sequences
3458       (Section 7.1)".
3459    
3460       By default, that is as initial routing, the effect send's audio
3461       channels are automatically routed to the last audio channels of the
3462       sampler channel's audio output device, that way you can i.e. first
3463       increase the amount of audio channels on the audio output device for
3464       having dedicated effect send output channels and when "CREATE
3465       FX_SEND" is called, those channels will automatically be picked.  You
3466       can alter the destination channels however with "SET FX_SEND
3467       AUDIO_OUTPUT_CHANNEL" (Section 6.4.31).

3474    
3475    
3476       Note: Create effect sends on a sampler channel only when needed,
3477       because having effect sends on a sampler channel will decrease
3478       runtime performance, because for implementing channel effect sends,
3479       separate (sampler channel local) audio buffers are needed to render
3480       and mix the voices and route the audio signal afterwards to the
3481       master outputs and effect send outputs (along with their respective
3482       effect send levels).  A sampler channel without effect sends however
3483       can mix its voices directly into the audio output devices's audio
3484       buffers and is thus faster.

3718    
3719       The front-end can alter the destination of an effect send's audio
3720       channel on a specific sampler channel by sending the following
3721       command:
3722    
3723          SET FX_SEND AUDIO_OUTPUT_CHANNEL <sampler-chan> <fx-send-id>
3724          <audio-src> <audio-dst>
3725    
3726       Where <sampler-chan> is the sampler channel number as returned by the
3727       "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4)
3728       command, <fx-send-id> reflects the numerical ID of the effect send
3729       entity as returned by the "CREATE FX_SEND" (Section 6.4.25) or "LIST
3730       FX_SENDS" (Section 6.4.28) command, <audio-src> is the numerical ID
3731       of the effect send's audio channel which should be rerouted and
3732       <audio-dst> is the numerical ID of the audio channel of the selected
3733       audio output device where <audio-src> should be routed to.
3734    
3735       Note that effect sends can only route audio to the same audio output
3736       device as assigned to the effect send's sampler channel.  Also note
3737       that an effect send entity does always have exactly as much audio
3738       channels as its sampler channel.  So if the sampler channel is
3739       stereo, the effect send does have two audio channels as well.  Also
3740       keep in mind that the amount of audio channels on a sampler channel
3741       might be dependant not only to the deployed sampler engine on the
3742       sampler channel, but also dependant to the instrument currently
3743       loaded.  However you can (effectively) turn an i.e. stereo effect
3744       send into a mono one by simply altering its audio routing
3745       appropriately.

4541    
4542       By default, "MAP MIDI_INSTRUMENT" commands block until the mapping is
4543       completely established in the sampler.  The OPTIONAL "NON_MODAL"
4544       argument however causes the respective "MAP MIDI_INSTRUMENT" command
4545       to return immediately, that is to let the sampler establish the
4546       mapping in the background.  So this argument might be especially
4547       useful for mappings with a "PERSISTENT" type, because these have to
4548       load the respective instruments immediately and might thus block for
4549       a very long time.  It is recommended however to use the OPTIONAL
4550       "NON_MODAL" argument only if really necessary, because it has the
4551       following drawbacks: as "NON_MODAL" instructions return immediately,
4552       they may not necessarily return an error i.e. when the given
4553       instrument file turns out to be corrupt, beside that subsequent
4554       commands in a LSCP instruction sequence might fail, because mandatory
4555       mappings are not yet completed.

5281    6.8.11.  Adding instruments to the instruments database
5282    
5283       The front-end can add one or more instruments to the instruments
5284       database by sending the following command:
5285    
5286          ADD DB_INSTRUMENTS [NON_MODAL] [<mode>] <db_dir> <file_path>
5287          [<instr_index>]
5288    
5289       Where <db_dir> is the absolute path name of a directory (encapsulated
5290       into apostrophes) in the instruments database in which only the new
5291       instruments (that are not already in the database) will be added,
5292       <file_path> is the absolute path name of a file or directory in the
5293       file system (encapsulated into apostrophes).  In case an instrument
5294       file is supplied, only the instruments in the specified file will be
5295       added to the instruments database.  If the optional <instr_index>
5296       (the index of the instrument within the given file) is supplied too,
5297       then only the specified instrument will be added.  In case a
5298       directory is supplied, the instruments in that directory will be
5299       added.  The OPTIONAL <mode> argument is only applied when a directory
5300       is provided as <file_path> and specifies how the scanning will be
5301       done and has exactly the following possibilities:
5302    
5303          "RECURSIVE" -
5304    
5305             All instruments will be processed, including those in the
5306             subdirectories, and the respective subdirectory tree structure
5307             will be recreated in the instruments database
5308    
5309          "NON_RECURSIVE" -
5310    
5311             Only the instruments in the specified directory will be added,
5312             the instruments in the subdirectories will not be processed.

5325    
5326             All instruments will be processed, including those in the
5327             subdirectories, but the respective subdirectory structure will
5328             not be recreated in the instruments database.  All instruments
5329             will be added directly in the specified database directory.
5330    
5331       The difference between regular and NON_MODAL versions of the command
5332       is that the regular command returns when the scanning is finished
5333       while NON_MODAL version returns immediately and a background process
5334       is launched.  The GET DB_INSTRUMENTS_JOB INFO (Section 6.8.21)
5335       command can be used to monitor the scanning progress.

5727    6.8.20.  Finding instruments
5728    
5729       The front-end can search for instruments in specific directory by
5730       sending the following command:
5731    
5732          FIND DB_INSTRUMENTS [NON_RECURSIVE] <dir> <criteria-list>
5733    
5734       Where <dir> should be replaced by the absolute path name of the
5735       directory to search in.  If NON_RECURSIVE is specified, the
5736       directories located in subdirectories of the specified directory will
5737       not be searched. <criteria-list> is a list of search criterias in
5738       form of "key1=val1 key2=val2 ...".  The following criterias are
5739       allowed:
5740    
5741       NAME='<search-string>'
5742    
5743          Restricts the search to instruments, which names satisfy the

5943    
5944    6.9.  Editing Instruments
5945    
5946       The sampler allows to edit instruments while playing with the sampler
5947       by spawning an external (3rd party) instrument editor application for
5948       a given instrument.  The 3rd party instrument editor applications
5949       have to place a respective plugin DLL file into the sampler's plugins
5950       directory.  The sampler will automatically try to load all plugin
5951       DLLs in that directory on startup and only on startup!
5952    
5953       At the moment there is only one command for this feature set, but
5954       this will most probably change in future.
5955    
5956    6.9.1.  Opening an appropriate instrument editor application
5957    
5958       The front-end can request to open an appropriate instrument editor
5959       application by sending the following command:
5960    
5961          EDIT CHANNEL INSTRUMENT <sampler-channel>
5962    
5963       Where <sampler-channel> should be replaced by the number of the
5964       sampler channel as given by the "ADD CHANNEL" (Section 6.4.5) or
5965       "LIST CHANNELS" (Section 6.4.4) command.
5966    
5967       The sampler will try to ask all registered instrument editors (or to
5968       be more specific: their sampler plugins) whether they are capable to
5969       handle the instrument on the given sampler channel.  The sampler will
5970       simply use the first instrument editor application which replied with
5971       a positive answer and spawn that instrument editor application within
5972       the sampler's process and provide that application access to the
5973       instrument's data structures, so both applications can share and
5974       access the same instruments data at the same time, thus allowing to
5975       immediately hear changes with the sampler made by the instrument
5976       editor.
5977    
5978       Note: consequently instrument editors are always spawned locally on
5979       the same machine where the sampler is running on!

6814    7.1.  Character Set and Escape Sequences
6815    
6816       Older versions of this protocol up to and including v1.1 only
6817       supported the standard ASCII character set (ASCII code 0 - 127)
6818       [RFC20], all younger versions of this protocol however support the
6819       Extended ASCII character set (ASCII code 0 - 255).  The same group of
6820       younger protocols also support escape sequences, but only for
6821       certain, explicitly declared parts of the protocol.  The supported
6822       escape sequences are defined as follows:

6862    
6863       Notice: due to the transition of certain parts of the protocol which
6864       now support escape sequences, a slight backward incompatibility to
6865       protocols version v1.1 and younger has been introduced.  The only
6866       difference is that in parts of the protocol where escape characters
6867       are now supported, a backslash characters MUST be escaped as well
6868       (that is as double backslash), whereas in the old versions a single
6869       backslash was sufficient.

6932       Note that the forward slash character ('/') has a special meaning in
6933       filename / path based arguments: it acts as separator of the nodes in
6934       the path, thus if a directory- or filename includes a forward slash
6935       (not intended as path node separator), you MUST escape that slash
6936       either with the respective hex escape sequence ("\x2f") or with the
6937       respective octal escape sequence ("\057").
