The following documents define the <i>LinuxSampler Control Protocol</i>, |

a network protocol with which LinuxSampler can be controlled locally as well as remotely. |

As this is a simple ASCII based protocol it's possible to write a frontend for LinuxSampler in |
| 171 |
|

any programming language and GUI library. There's still a big demand especially for a Gtk and |
| 172 |
|

ncurses based frontend, so be encouraged and let |

examples to give you a good starting point for writing your own ones. Adjust it to your needs |

sampler session for your needs and save it. Because you have to know that the files saved |
| 271 |
|
|
by our frontends are actually pure LSCP scripts, thus you can i.e. use those files simply with |
| 272 |
|
|
the mentioned netcat command from above to setup the sampler session without a frontend. |

Here is a simple LSCP example which uses ALSA as MIDI input and as audio output driver as well, |
| 276 |
|
|
it creates only one sampler channel using the Gigasampler engine and loads a Piano instrument |
| 277 |
|
|
on that sampler channel: |

The next example uses JACK as audio output driver instead and automatically connects the two |
| 310 |
|
|
output channels of LS's JACK client to the first two ALSA PCM channels, so you can hear |
| 311 |
|
|
something without having to manually connect it e.g. with qjackctl: |

The next example is a bit more complex. |
| 347 |
|
|
It shows how to setup a more realistic sampler session, handle routing of MIDI input channels, |
| 348 |
|
|
handle routing of audio channels, it uses JACK again as audio |
| 349 |
|
|
output driver, but creates the JACK client with four output channels instead, it creates two |
| 350 |
|
|
sampler channels, loads two different instrument on those two sampler channels and alters |
| 351 |
|
|
the audio channel routing so that the two output channels of sampler channel 1 are routed to |
| 352 |
|
|
the first two JACK output channels and the two output channels of sampler channel 2 are routed |
| 353 |
|
|
the second pair of the JACK client's output channels. That way you could e.g. record the output |
| 354 |
|
|
of those two sampler channels independently or apply independent LADSPA effects on it. |
