3621    6.7.  MIDI Instrument Mapping
3622    
3623       The MIDI protocol provides a way to switch between instruments by
3624       sending so called MIDI bank select and MIDI program change messages
3625       which are essentially just numbers.  The following commands allow to
3626       actually map arbitrary MIDI bank select / program change numbers with
3627       real instruments.
3628    
3629       The sampler allows to manage an arbitrary amount of MIDI instrument
3630       maps which define which instrument to load on which MIDI program
3631       change message.
3632    
3633       By default, that is when the sampler is launched, there is no map,
3634       thus the sampler will simply ignore all program change messages.  The
3635       front-end has to explicitly create at least one map, add entries to
3636    
3637

3642    
3643    
3644       the map and tell the respective sampler channel(s) which MIDI
3645       instrument map to use, so the sampler knows how to react on a given
3646       program change message on the respective sampler channel, that is by
3647       switching to the respectively defined engine type and loading the
3648       respective instrument.  See command "SET CHANNEL MIDI_INSTRUMENT_MAP"
3649       (Section 6.4.24) for how to assign a MIDI instrument map to a sampler
3650       channel.
3651    
3652       Also note per MIDI specification a bank select message does not cause
3653       to switch to another instrument.  Instead when receiving a bank
3654       select message the bank value will be stored and a subsequent program
3655       change message (which may occur at any time) will finally cause the
3656       sampler to switch to the respective instrument as reflected by the
3657       current MIDI instrument map.
3658    
3659    6.7.1.  Create a new MIDI instrument map
3660    
3661       The front-end can add a new MIDI instrument map by sending the
3662       following command:
3663    
3664          ADD MIDI_INSTRUMENT_MAP [<name>]
3665    
3666       Where <name> is an optional argument allowing to assign a custom name
3667       to the new map.  MIDI instrument Map names do not have to be unique.

3670    
3671          "OK[<map>]" -

3869          <filename> <instrument_index> <volume_value> [<instr_load_mode>]
3870          [<name>]
3871    
3872       Where <map> is the numeric ID of the map to alter, <midi_bank> is an
3873       integer value between 0..16383 reflecting the MIDI bank select index,
3874       <midi_prog> an integer value between 0..127 reflecting the MIDI
3875       program change index, <engine_name> a sampler engine name as returned
3876       by the "LIST AVAILABLE_ENGINES" (Section 6.4.8) command (not
3877       encapsulated into apostrophes), <filename> the name of the
3878       instrument's file to be deployed (encapsulated into apostrophes),
3879       <instrument_index> the index (integer value) of the instrument within
3880       the given file, <volume_value> reflects the master volume of the
3881       instrument as optionally dotted number (where a value < 1.0 means
3882       attenuation and a value > 1.0 means amplification).  This parameter
3883       easily allows to adjust the volume of all intruments within a custom
3884       instrument map without having to adjust their instrument files.  The
3885       OPTIONAL <instr_load_mode> argument defines the life time of the
3886       instrument, that is when the instrument should be loaded, when freed
3887       and has exactly the following possibilities:
3888    
3889          "ON_DEMAND" -
3890    
3891             The instrument will be loaded when needed, that is when
3892             demanded by at least one sampler channel.  It will immediately
3893             be freed from memory when not needed by any sampler channel
3894             anymore.
3895    
3896          "ON_DEMAND_HOLD" -
3897    
3898             The instrument will be loaded when needed, that is when
3899             demanded by at least one sampler channel.  It will be kept in
3900             memory even when not needed by any sampler channel anymore.
3901             Instruments with this mode are only freed when the sampler is
3902             reset or all mapping entries with this mode (and respective
3903             instrument) are explicitly changed to "ON_DEMAND" and no
3904             sampler channel is using the instrument anymore.
3905    
3906          "PERSISTENT" -
3907    
3908             The instrument will immediately be loaded into memory in the
3909             background when this mapping command is sent and the instrument
3910             is kept all the time.  Instruments with this mode are only
3911             freed when the sampler is reset or all mapping entries with
3912             this mode (and respective instrument) are explicitly changed to
3913             "ON_DEMAND" and no sampler channel is using the instrument
3914             anymore.

3922    
3923    
3924          not supplied -
3925    
3926             In case there is no <instr_load_mode> argument given, it will
3927             be up to the InstrumentManager to decide which mode to use.
3928             Usually it will use "ON_DEMAND" if an entry for the given
3929             instrument does not exist in the InstrumentManager's list yet,
3930             otherwise if an entry already exists, it will simply stick with
3931             the mode currently reflected by the already existing entry,
3932             that is it will not change the mode.
3933    
3934       The <instr_load_mode> argument thus allows to define an appropriate
3935       strategy (low memory consumption vs. fast instrument switching) for
3936       each instrument individually.  Note, the following restrictions apply
3937       to this argument: "ON_DEMAND_HOLD" and "PERSISTENT" have to be
3938       supported by the respective sampler engine (which is technically the
3939       case when the engine provides an InstrumentManager for its format).
3940       If this is not the case the argument will automatically fall back to
3941       the default value "ON_DEMAND".  Also the load mode of one instrument
3942       may automatically change the laod mode of other instrument(s), i.e.
3943       because the instruments are part of the same file and the engine does
3944       not allow a way to manage load modes for them individually.  Due to
3945       this, in case the frontend shows the load modes of entries, the
3946       frontend should retrieve the actual mode by i.e. sending "GET
3947       MIDI_INSTRUMENT INFO" (Section 6.7.11) command(s).  Finally the
3948       OPTIONAL <name> argument allows to set a custom name (encapsulated
3949       into apostrophes) for the mapping entry, useful for frontends for
3950       displaying an appropriate name for mapped instruments (using "GET
3951       MIDI_INSTRUMENT INFO" (Section 6.7.11)).
3952    
3953       The "MAP MIDI_INSTRUMENT" command will immediately return, thus it
3954       will not block when an instrument is to be loaded due to a
3955       "PERSISTENT" type entry as instruments are loaded in the background.
3956       As a consequence this command may not necessarily return an error
3957       i.e. when the given instrument file does not exist or may turn out to
3958       be corrupt.

4005    6.7.8.  Getting ammount of MIDI instrument map entries
4006    
4007       The front-end can query the amount of currently existing entries in a
4008       MIDI instrument map by sending the following command:
4009    
4010          GET MIDI_INSTRUMENTS <map>
4011    
4012       The front-end can query the amount of currently existing entries in
4013       all MIDI instrument maps by sending the following command:
4014    
4015          GET MIDI_INSTRUMENTS ALL
4016    
4017       Possible Answers:
4018    
4019          The sampler will answer by sending the current number of entries
4020          in the MIDI instrument map(s).
4021    
4022       Example:
4023    
4024          C: "GET MIDI_INSTRUMENTS 0"

4040    6.7.9.  Getting indeces of all entries of a MIDI instrument map
4041    
4042       The front-end can query a list of all currently existing entries in a
4043       certain MIDI instrument map by sending the following command:
4044    
4045          LIST MIDI_INSTRUMENTS <map>
4046    
4047       Where <map> is the numeric ID of the MIDI instrument map.
4048    
4049       The front-end can query a list of all currently existing entries of
4050       all MIDI instrument maps by sending the following command:
4051    
4052          LIST MIDI_INSTRUMENTS ALL
4053    
4054       Possible Answers:
4055    
4056          The sampler will answer by sending a comma separated list of map
4057          ID - MIDI bank - MIDI program triples, where each triple is
4058          encapsulated into curly braces.  The list is returned in one
4059          single line.  Each triple just reflects the key of the respective
4060          map entry, thus subsequent "GET MIDI_INSTRUMENT INFO"
4061          (Section 6.7.11) command(s) are necessary to retrieve detailed
4062          informations about each entry.
4063    
4064       Example:
4065    
4066          C: "LIST MIDI_INSTRUMENTS 0"
4067    
4068          S: "{0,0,0},{0,0,1},{0,0,3},{0,1,4},{1,127,127}"

4070    6.7.10.  Remove an entry from the MIDI instrument map
4071    
4072       The front-end can delete an entry from a MIDI instrument map by
4073       sending the following command:
4074    
4075          UNMAP MIDI_INSTRUMENT <map> <midi_bank> <midi_prog>
4076    
4077       Where <map> is the numeric ID of the MIDI instrument map, <midi_bank>
4078       is an integer value between 0..16383 reflecting the MIDI bank value
4079       and <midi_prog> an integer value between 0..127 reflecting the MIDI
4080       program value of the map's entrie's key index triple.

4110    
4111          GET MIDI_INSTRUMENT INFO <map> <midi_bank> <midi_prog>
4112    
4113       Where <map> is the numeric ID of the MIDI instrument map, <midi_bank>
4114       is an integer value between 0..16383 reflecting the MIDI bank value,
4115       <midi_bank> and <midi_prog> an integer value between 0..127

4119       Possible Answers:
4120    
4121          LinuxSampler will answer by sending a <CRLF> separated list.  Each
4122          answer line begins with the information category name followed by
4123          a colon and then a space character <SP> and finally the info
4124          character string to that info category.  At the moment the
4125          following categories are defined:
4126    
4127          "NAME" -
4128    
4129             Name for this MIDI instrument map entry (if defined).  This
4130             name shall be used by frontends for displaying a name for this
4131             mapped instrument.  It can be set and changed with the "MAP
4132             MIDI_INSTRUMENT" (Section 6.7.7) command and does not have to
4133             be unique.
4134    
4135          "ENGINE_NAME" -
4136    
4137             Name of the engine to be deployed for this instrument.

4153    
4154             Index of the instrument within the file.
4155    
4156          "INSTRUMENT_NAME" -
4157    
4158             Name of the loaded instrument as reflected by its file.  In
4159             contrast to the "NAME" field, the "INSTRUMENT_NAME" field
4160             cannot be changed.
4161    
4162          "LOAD_MODE" -
4163    
4164             Life time of instrument (see "MAP MIDI_INSTRUMENT"
4165             (Section 6.7.7) for details about this setting).
4166    
4167          "VOLUME" -
4168    
4169             master volume of the instrument as optionally dotted number
4170             (where a value < 1.0 means attenuation and a value > 1.0 means
4171             amplification)

4204    6.7.12.  Clear MIDI instrument map
4205    
4206       The front-end can clear a whole MIDI instrument map, that is delete
4207       all its entries by sending the following command:
4208    
4209          CLEAR MIDI_INSTRUMENTS <map>
4210    
4211       Where <map> is the numeric ID of the map to clear.
4212    
4213       The front-end can clear all MIDI instrument maps, that is delete all
4214       entries of all maps by sending the following command:
4215    
4216          CLEAR MIDI_INSTRUMENTS ALL
4217    
4218       The command "CLEAR MIDI_INSTRUMENTS ALL" does not delete the maps,
4219       only their entries, thus the map's settings like custom name will be
4220       preservevd.
