Halion Sonic SE not responding to midi keyboard

I’m having the same issue. the midi channel of the plugin is matched with th e one of the instrument track. But halion is neither responding to the midi keyboard nor the sound is playing. The green midi light at the top left also doesn’t show. But if I press the keys of the keyboard in the plugin I can hear sound. Can anyone help me with this?

You have all the slots empty in your screenshot. You need to load a program into some of the slots.
