4764 |
|
* The positions of the scripts in the Instrument's Script list are |
4765 |
|
* relevant, because they define in which order they shall be executed by |
4766 |
|
* the sampler. For this reason it is also legal to add the same script |
4767 |
|
* twice to an instrument, for example you might have a script called |
4768 |
|
* "MyFilter" which performs an event filter task, and you might have |
4769 |
|
* another script called "MyNoteTrigger" which triggers new notes, then you |
4770 |
|
* might for example have the following list of scripts on the instrument: |
4771 |
|
* |
4772 |
|
* 1. Script "MyFilter" |
4773 |
|
* 2. Script "MyNoteTrigger" |
4774 |
|
* 3. Script "MyFilter" |
4775 |
|
* |
4776 |
|
* Which would make sense, because the 2nd script launched new events, which |
4777 |
|
* you might need to filter as well. |
4778 |
|
* |
4779 |
|
* There are two ways to disable / "bypass" scripts. You can either disable |
4780 |
|
* a script locally for the respective script slot on an instrument (i.e. by |
4781 |
|
* passing @c false to the 2nd argument of this method, or by calling |
4782 |
|
* SetScriptBypassed()). Or you can disable a script globally for all slots |
4783 |
|
* and all instruments by setting Script::Bypass. |
