This is a little experiment and basicaly the emulating of Vienna Ensemble matrix keyswitches.

At the first channel of G-player I load two violin staccato patches in stacked mode with key switches on C1 - C#1 and then through violin midi line add that changes.
Sound not bad.
Main idea is to fast switch between two articulation staccato and second type of staccato to emulate real up-down bowing.
