3368    6.4.25.  Adding an effect send to a sampler channel
3369    
3370       The front-end can create an additional effect send on a specific
3371       sampler channel by sending the following command:
3372    
3373          CREATE FX_SEND <sampler-channel> <midi-ctrl> [<name>]
3374    
3375       Where <sampler-channel> is the respective sampler channel number as
3376       returned by the "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS"
3377       (Section 6.4.4) command, that is the sampler channel on which the
3378       effect send should be created on, <midi-ctrl> is a number between
3379       0..127 defining the MIDI controller which can alter the effect send
3380       level and <name> is an optional argument defining a name for the
3381       effect send entity.  The name does not have to be unique.
3382    
3383       By default, that is as initial routing, the effect send's audio
3384       channels are automatically routed to the last audio channels of the
3385       sampler channel's audio output device, that way you can i.e. first
3386       increase the amount of audio channels on the audio output device for
3387       having dedicated effect send output channels and when "CREATE
3388       FX_SEND" is called, those channels will automatically be picked.  You
3389       can alter the destination channels however with "SET FX_SEND
3390       AUDIO_OUTPUT_CHANNEL" (Section 6.4.31).
3391    
3392       Note: Create effect sends on a sampler channel only when needed,
3393       because having effect sends on a sampler channel will decrease
3394       runtime performance, because for implementing channel effect sends,
3395       separate (sampler channel local) audio buffers are needed to render
3396       and mix the voices and route the audio signal afterwards to the
3397       master outputs and effect send outputs (along with their respective
3398       effect send levels).  A sampler channel without effect sends however
3399       can mix its voices directly into the audio output devices's audio
3400       buffers and is thus faster.

3573                of the selected audio output device each effect send output
3574                channel is routed to, e.g. "0,3" would mean the effect
3575                send's output channel 0 is routed to channel 0 of the audio

3644    6.4.31.  Altering effect send's audio routing
3645    
3646       The front-end can alter the destination of an effect send's audio
3647       channel on a specific sampler channel by sending the following
3648       command:
3649    
3650          SET FX_SEND AUDIO_OUTPUT_CHANNEL <sampler-chan> <fx-send-id>
3651          <audio-src> <audio-dst>
3652    
3653       Where <sampler-chan> is the sampler channel number as returned by the
3654       "ADD CHANNEL" (Section 6.4.5) or "LIST CHANNELS" (Section 6.4.4)
3655       command, <fx-send-id> reflects the numerical ID of the effect send
3656       entity as returned by the "CREATE FX_SEND" (Section 6.4.25) or "LIST
3657       FX_SENDS" (Section 6.4.28) command, <audio-src> is the numerical ID
3658       of the effect send's audio channel which should be rerouted and
3659       <audio-dst> is the numerical ID of the audio channel of the selected
3660       audio output device where <audio-src> should be routed to.
3661    
3662       Note that effect sends can only route audio to the same audio output
3663       device as assigned to the effect send's sampler channel.  Also note
3664       that an effect send entity does always have exactly as much audio
3665       channels as its sampler channel.  So if the sampler channel is
3666       stereo, the effect send does have two audio channels as well.  Also
3667       keep in mind that the amount of audio channels on a sampler channel
3668       might be dependant not only to the deployed sampler engine on the
3669       sampler channel, but also dependant to the instrument currently
3670       loaded.  However you can (effectively) turn an i.e. stereo effect
3671       send into a mono one by simply altering its audio routing
3672       appropriately.

4050    6.6.5.  Getting global volume attenuation
4051    
4052       The client can ask for the current global sampler-wide volume
4053       attenuation by sending the following command:
4054    
4055          GET VOLUME
4056    
4057       Possible Answers:
4058    
4059          The sampler will always answer by returning the optional dotted
4060          floating point coefficient, reflecting the current global volume
4061          attenuation.
4062    
4063       Note: it is up to the respective sampler engine whether to obey that
4064       global volume parameter or not, but in general all engines SHOULD use
4065       this parameter.
4066    
4067    6.6.6.  Setting global volume attenuation
4068    
4069       The client can alter the current global sampler-wide volume
4070       attenuation by sending the following command:
4071    
4072          SET VOLUME <volume>
4073    
4074       Where <volume> should be replaced by the optional dotted floating
4075       point value, reflecting the new global volume parameter.  This value
4076       might usually be in the range between 0.0 and 1.0, that is for
4077       attenuating the overall volume.
