* script will be added to the end of the script list of this instrument. |
5145 |
|
* The positions of the scripts in the Instrument's Script list are |

* relevant, because they define in which order they shall be executed by |
5147 |
|
* the sampler. For this reason it is also legal to add the same script |
5148 |
|
* twice to an instrument, for example you might have a script called |
5149 |
|
* "MyFilter" which performs an event filter task, and you might have |
5150 |
|
* another script called "MyNoteTrigger" which triggers new notes, then you |
5151 |
|
* might for example have the following list of scripts on the instrument: |
5152 |
|
* |
5153 |
|
* 1. Script "MyFilter" |
5154 |
|
* 2. Script "MyNoteTrigger" |
5155 |
|
* 3. Script "MyFilter" |
5156 |
|
* |
5157 |
|
* Which would make sense, because the 2nd script launched new events, which |
5158 |
|
* you might need to filter as well. |
5159 |
|
* |
5160 |
|
* There are two ways to disable / "bypass" scripts. You can either disable |
5161 |
|
* a script locally for the respective script slot on an instrument (i.e. by |
5162 |
|
* passing @c false to the 2nd argument of this method, or by calling |
5163 |
|
* SetScriptBypassed()). Or you can disable a script globally for all slots |

|
* and all instruments by setting Script::Bypass. |
