4067 |
|
* loading all Regions, DimensionRegions and especially samples might |
4068 |
|
* take a long time for large .gig files, and sometimes one might only |
4069 |
|
* be interested in retrieving very superficial informations like the |
4070 |
|
* amount of instruments and their names. In this case one might disable |
4071 |
|
* automatic loading to avoid very slow response times. |

4073 |
|
* @e CAUTION: by disabling this property many pointers (i.e. sample |
4074 |
|
* references) and informations will have invalid or even undefined |
4075 |
|
* data! This feature is currently only intended for retrieving very |
4076 |
|
* superficial informations in a very fast way. Don't use it to retrieve |
4077 |
|
* details like synthesis informations or even to modify .gig files! |
