14    
15       The LinuxSampler Control Protocol (LSCP) is an application-level
16       protocol primarily intended for local and remote controlling the
17       LinuxSampler backend application, which is a sophisticated server-
18       like console application essentially playing back audio samples and
19       manipulating the samples in real time to certain extent.

 Abstract  
307    
    The LinuxSampler Control Protocol (LSCP) is an application-level  
    protocol primarily intended for local and remote controlling the  
    LinuxSampler backend application, which is a sophisticated server-  
    like console application essentially playing back audio samples and  
    manipulating the samples in real time to certain extent.

4448          LinuxSampler will answer by returning the number for the current
4449          limit of maximum voices.
4450    
4451       The voice limit setting defines how many voices should maximum be
4452       processed by the sampler at the same time.  If the user triggers new
4453       notes which would exceed that voice limit, the sampler engine will
4454       react by stealing old voices for those newly triggered notes.  Note
4455       that the amount of voices triggered by a new note can be larger than
4456       one and is dependent to the respective instrument and probably
4457       further criterias.
4458    
4459    6.6.9.  Setting global voice limit
4460    
4461       The client can alter the current global sampler-wide limit for
4462       maximum voices by sending the following command:
4463    
4464          SET VOICES <max-voices>
4465    
4466       Where <max-voices> should be replaced by the integer value,
4467       reflecting the new global amount limit of maximum voices.  This value
4468       has to be larger than 0.

4500       Caution: when adjusting the voice limit, you SHOULD also adjust the
4501       disk stream limit respectively and vice versa.
4502    
4503    6.6.10.  Getting global disk stream limit
4504    
4505       The client can ask for the current global sampler-wide limit for
4506       maximum disk streams by sending the following command:
4507    
4508          GET STREAMS
4509    
4510       Possible Answers:
4511    
4512          LinuxSampler will answer by returning the number for the current
4513          limit of maximum disk streams.
4514    
4515       The disk stream limit setting defines how many disk streams should
4516       maximum be processed by a sampler engine at the same time.  The
4517       higher this value, the more memory (RAM) will be occupied, since
4518       every disk streams allocates a certain buffer size for being able to
4519       perform its streaming operations.
4520    
4521    6.6.11.  Setting global disk stream limit
4522    
4523       The client can alter the current global sampler-wide limit for
4524       maximum disk streams by sending the following command:
4525    
4526          SET STREAMS <max-streams>
4527    
4528       Where <max-streams> should be replaced by the integer value,
4529       reflecting the new global amount limit of maximum disk streams.  This
4530       value has to be positive.

6636    
6637    6.11.  Managing Effects
6638    
6639       Audio effects (e.g. reverb, delay, compression) can be applied to the
6640       audio signals generated by the sampler.  The sampler usually provides
6641       a set of internal audio effects for this task.  The exact set of
6642       effects depends on the availability of third party effect plugins
6643       installed on the system where the sampler runs on.
6644    
6645       At the moment only "send effects" are supported.  Support for "insert
6646       effects" and "master effects" is planned to be added at a later
6647       point.
6648    
6649       The following commands allow to retrieve the set of internal effects
6650       available to the sampler, detailed informations about those effects
6651       and to create and destroy instances of such effects.  After an
6652       instance of an effect is created, the effect instance can be inserted
6653       into the audio signal path of the sampler, e.g. as send effect.
6654    
6655       The sampler allows to create an arbitrary amount of so called send
6656       effect chains.  Each effect chain can host an arbitrary amount of
6657       effect instances.  The output of the first effect instance in an
6658       effect chain is fed to the input of the second effect instance of the
6659       chain and so on.  So effects in one chain are processed sequentially.
6660

6665    Internet-Draft        LinuxSampler Control Protocol         October 2010
6666    
6667    
6668       Send effect chains however are processed in parallel to other send
6669       effect chains.  Audio signals of sampler channels are fed to send
6670       effects by creating FX sends to the respective sampler channel and
6671       assigning a destination send effect to that FX by using the "SET
6672       FX_SEND SEND_EFFECT" (Section 6.4.32) command.  The latter allows to
6673       route the FX send to the beginning of a send effect chain, as well as
6674       directly to any other position of the send effect chain.
6675    
6676    6.11.1.  Retrieve amount of available effects
6677    
6678       The front-end can retrieve the amount of internal effects, available
6679       to the sampler by sending the following command:
6680    
6681          GET AVAILABLE_EFFECTS
6682    
6683       Possible Answers:
6684    
6685          The sampler will answer by returning the current number of effects
6686          available to the sampler.
6687    
6688       Examples:
6689    
6690          C: "GET AVAILABLE_EFFECTS"
6691    
6692          S: "129"
6693    
6694    6.11.2.  Get list of available effects
6695    
6696       The set of available internal effects can change at runtime.  The
6697       front-end can retrieve the list of internal effects, available to the
6698       sampler by sending the following command:
6699    
6700          LIST AVAILABLE_EFFECTS
6701    
6702       Possible Answers:
6703    
6704          The sampler will answer by returning a comma separated list with
6705          numerical IDs of effects.  Note: the numercial ID of an effect is
6706          generated by the sampler for the current moment.  The numerical ID
6707          of the same effect can change at runtime, e.g. when the user
6708          requests a rescan of available effect plugins.
6709    
6710       Example:
6711    
6712          C: "LIST AVAILABLE_EFFECTS"
6713    
6714          S: "5,6,7,120,121,122,123,124"

6725    
6726       The front-end can ask for general informations about an effect by
6727       sending the following command:
6728    
6729          GET EFFECT INFO <effect-index>
6730    
6731       Where <effect-index> is the numerical ID of an effect as returned by
6732       the "LIST AVAILABLE_EFFECTS" (Section 6.11.2) command.
6733    
6734       Possible Answers:
6735    
6736          LinuxSampler will answer by sending a <CRLF> separated list.  Each
6737          answer line begins with the effect information category name,
6738          followed by a colon and then a space character <SP> and finally
6739          the info character string to that effect information category.  At
6740          the moment the following categories are defined:
6741    
6742    
6743    
6744             SYSTEM -
6745    
6746                name of the effect plugin system the effect is based on
6747                (e.g.  "LADSPA")
6748    
6749             MODULE -
6750    
6751                module of the effect plugin system that contains this
6752                effect, the module is usually the dynamic-linked library
6753                (DLL) filename of the effect plugin, including full path
6754                (note that this filename may contain escape sequences
6755                (Section 7.1))
6756    
6757             NAME -
6758    
6759                character string defining the unique name of the effect
6760                within its module (note that the character string may
6761                contain escape sequences (Section 7.1))
6762    
6763             DESCRIPTION -
6764    
6765                human readable name of the effect, intended to be displayed
6766                in user interfaces (note that the character string may
6767                contain escape sequences (Section 7.1))

6792    6.11.4.  Creating an instance of an effect by its portable ID
6793    
6794       The front-end can spawn an instance of the desired effect by sending
6795       the following command:
6796    
6797          CREATE EFFECT_INSTANCE <effect-system> <module> <effect-name>
6798    
6799       Where <effect-system> is the "SYSTEM" field, <module> the "MODULE"
6800       field and <effect-name> the "NAME" field as returned by the "GET
6801       EFFECT INFO" (Section 6.11.3) command.  The filename of argument
6802       <module> and the character string of argument <effect-name> may
6803       contain escape sequences (Section 7.1).
6804    
6805       The sampler will try to load the requested effect and to create an
6806       instance of it.  To allow loading the same effect on a different
6807       machine, probably even running a completely different operating
6808       system (e.g.  Linux vs. Windows), the sampler tries to match <module>
6809       "softly".  That means it first tries to find an effect that exactly
6810       matches the given <module> argument.  If there is no exact match, the
6811       sampler will try to lower the restrictions on matching the <module>
6812       argument more and more, e.g. by ignoring upper / lower case
6813       differences and by ignoring the path of the DLL filename and file
6814       extension.  If there is still no match at the end, the sampler will
6815       try to ignore the <module> argument completely and as a last resort
6816       search for an effect that only matches the given <effect-system> and
6817       <effect-name> arguments.

6853    6.11.5.  Creating an instance of an effect by its numerical ID
6854    
6855       The front-end can spawn an instance of the desired effect by sending
6856       the following command:
6857    
6858          CREATE EFFECT_INSTANCE <effect-index>
6859    
6860       Where <effect-index> is the numerical ID of the effect as returned by
6861       the "LIST AVAILABLE_EFFECTS" (Section 6.11.2) command.
6862    
6863       The sampler will try to load the requested effect and to create an
6864       instance of it.
6865    
6866       Note: Since the numerical ID of a certain effect can change at any
6867       time, you should not use this command in LSCP files to restore a
6868       certain effect at a later time!  To store a sampler session including
6869       all its effects, use the portable text-based version of "CREATE
6870       EFFECT_INSTANCE" (Section 6.11.4) instead!  This allows to restore a
6871       sampler session with all its effects also on other machines, possibly
6872       even running a completely different operating system (e.g.  Linux vs.
6873       Windows), with different plugin directories or plugin DLL names.

6909    
6910       The front-end can destroy an unusued effect instance and thus freeing
6911       it from memory by sending the following command:
6912    
6913          DESTROY EFFECT_INSTANCE <effect-instance>
6914    
6915       Where <effect-instance> is the numerical ID of the effect instance as

6917       EFFECT_INSTANCES" (Section 6.11.8) command.
6918    
6919       The effect instance can only be destroyed if it's not used in any
6920       part of the sampler's audio signal path anymore.  If the effect
6921       instance is still in use somewhere, trying to destroy the effect
6922       instance will result in an error message.

7077       can be altered by the user in realtime (e.g. depth of a reverb
7078       effect, duration of a delay effect, dry / wet signal ratio).  Those
7079       controllable effect parameters are called "input controls".  The
7080       front-end can ask for the current informations of an effect
7081       instance's input control by sending the following command:
7082    
7083          GET EFFECT_INSTANCE_INPUT_CONTROL INFO <effect-instance> <input-
