Somehow the keyswitches I use, randomly select the right articulations, or not. What happens is that I can see that the right key is pressed by the expression map in Cubase on the VE PRO instance keyboard, but the articulation activated is another one. When I rewind and play the same line again, then the right articulations are selected. This happens totally random and I simply can't find a way to solve it.
So, Cubase sends the right info, which I can see because the right key is pressed in the VE PRO keyboard, but somehow VE PRO switches to another articulation.
I've checked, but there is no hidden extra key in the expression map. Even with only two articulations like staccato and legato in a simple expression map, it simply won't select the right one from time to time.
Anyone have a suggestion how to get rid of this annoying behavior?

I'm on Windows 10, Cubase 10 (latest update) and VE pro 7
