* Enable / disable automatic loading. By default this properyt is |
4948 |
|
* enabled and all informations are loaded automatically. However |
4949 |
|
* loading all Regions, DimensionRegions and especially samples might |
4950 |
|
* take a long time for large .gig files, and sometimes one might only |
4951 |
|
* be interested in retrieving very superficial informations like the |
4952 |
|
* amount of instruments and their names. In this case one might disable |
4953 |
|
* automatic loading to avoid very slow response times. |
4954 |

4955 |
|
* @e CAUTION: by disabling this property many pointers (i.e. sample |
4956 |
|
* references) and informations will have invalid or even undefined |
4957 |
|
* data! This feature is currently only intended for retrieving very |
4958 |
|
* superficial informations in a very fast way. Don't use it to retrieve |
4959 |
|
* details like synthesis informations or even to modify .gig files! |
