# VSL Vienna Instruments Pro Libraries

The support for VSL libraries focuses on presets instead of matrices. VIPRO and Preset Level 1/2 are supported with dedicated Articulation Templates for every instrument. We deciphered all abbreviations VSL uses to describe their instruments. We’ve ignored certain aspects of the Level 1/2 instruments to limit the number of key switches needed. Those presets are called “@ Universal …” and you can switch to these but not select items within the matrices. For those, you need to use the conventional Key Switches VSL supplies, usually located from C1 onwards.
