How do I switch Vital to polyphonic mode?

[fabian.idem]

I would like to play a 3 chord progression in a bass preset. But Vital only plays one note from the 3. It seems to be a preset problem because in another lead preset it plays all 3. Does anyone know where I can switch to polyphonic mode?

Just change number of voices from 1 to more, here:

Thank you very much! It works
