Iconica Ensemble sustain tremolo preset works how?

Just bought it and just stuck at one point. How getting the “sustain/tremolo” to work. As you can see on the screenshot, it is set to “Gen.Purp2”.

Like this, you don’t get the tremolo to play. It keeps with sustain. What’s the trick?

Accented Tremolo works. Just keep holding the key, starts the tremolo.

Just found this on the walkthrough video from Steinberg. There the settings are different.
