<section title="Editing Instruments" anchor="editing_instruments"> |
6134 |
|
<t>The sampler allows to edit instruments while playing with the |
6135 |
|
sampler by spawning an external (3rd party) instrument editor |
6136 |
|
application for a given instrument. The 3rd party instrument |
6137 |
|
editor applications have to place a respective plugin DLL file |
6138 |
|
into the sampler's plugins directory. The sampler will |
6139 |
|
automatically try to load all plugin DLLs in that directory on |
6140 |
|
startup and only on startup!</t> |
6141 |
|
<t>At the moment there is only one command for this feature set, |
6142 |

but this will most probably change in future.</t> |

<section title="Opening an appropriate instrument editor application" anchor="EDIT INSTRUMENT"> |

<t>The front-end can request to open an appropriate instrument |

6156 |

command.</t> |
6157 |
|

6158 |
|
<t>The sampler will try to ask all registered instrument |
6159 |
|
editors (or to be more specific: their sampler plugins) |
6160 |
|
whether they are capable to handle the instrument on the |
6161 |
|
given sampler channel. The sampler will simply use the first |
6162 |
|
instrument editor application which replied with a positive |
6163 |
|
answer and spawn that instrument editor application within |
6164 |
|
the sampler's process and provide that application access |
6165 |
|
to the instrument's data structures, so both applications |
6166 |
|
can share and access the same instruments data at the same |
6167 |
|
time, thus allowing to immediately hear changes with the |
6168 |
|
sampler made by the instrument editor.</t> |
6169 |
|
|
6170 |
|
<t>Note: consequently instrument editors are always spawned |

on!</t> |

Note that the forward slash character ('/') has a special meaning in |
7249 |
|
filename / path based arguments: it acts as separator of the nodes in |
7250 |
|
the path, thus if a directory- or filename includes a forward slash |
7251 |
|
(not intended as path node separator), you MUST escape that slash |
7252 |
|
either with the respective hex escape sequence ("\x2f") or with the |
7253 |
|
respective octal escape sequence ("\057"). |

Note for Windows: file path arguments in LSCP are expected |
7258 |
|
to use forward slashes as directory node separator similar |
7259 |
|
to Unix based operating systems. In contrast to Unix however |
7260 |
|
a Windows typical drive character is expected to be |
7261 |
|
prefixed to the path. That is an original Windows file path |
7262 |
|
like "D:\Sounds\My.gig" would become in LSCP: |
7263 |
|
"D:/Sounds/My.gig". |
