/** @brief Drop overridden initial value(s) for 'patch' variable(s). |
5844 |
|
* |
5845 |
|
* Reverts initial value(s) for requested script variable(s) back to their |
5846 |
|
* default initial value(s) defined in the script itself. |
5847 |
|
* |
5848 |
|
* Both arguments of this method are optional. The most obvious use case of |
5849 |
|
* this method would be passing a valid script @p slot index and a |
5850 |
|
* (non-emtpy string as) @p variable name to this method, which would cause |
5851 |
|
* that single variable to be unset for that specific script slot (on this |
5852 |
|
* @c Instrument level). |
5853 |
|
* |
5854 |
|
* Not passing a value (or @c -1 for @p slot and/or empty string for |
5855 |
|
* @p variable) means 'wildcard'. So accordingly absence of argument(s) will |
5856 |
|
* cause all variables and/or for all script slots being unset. Hence this |
5857 |
|
* method serves 2^2 = 4 possible use cases in total and accordingly covers |
5858 |
|
* 4 different behaviours in one method. |
5859 |
|
* |
5860 |
|
* @remarks Real-time instrument scripts allow to declare special 'patch' |
5861 |
|
* variables, which essentially behave like regular variables of their data |
5862 |
|
* type, however their initial value may optionally be overridden on a per |
5863 |
|
* instrument basis. That allows to share scripts between instruments while |
5864 |
|
* still being able to fine tune certain aspects of the script for each |
5865 |
|
* instrument individually. |
5866 |
|
* |
5867 |
|
* @note This is an own format extension which did not exist i.e. in the |
5868 |
|
* GigaStudio 4 software. It will currently only work with LinuxSampler and |
5869 |
|
* Gigedit. |
5870 |
