Articulation switch with key switches in Valves Pro does not work

Salome

I use Valves Pro with Komplete Kontrol on a Macbook Pro M1.

In ‘Ensemble’ Mode’ i display the articulations list and i get a list of articulations and the associated keyswitches (C2, C#2, …).

To select an articulation i have to click on an item of the list. The key switches do not work.
