First Day in Ardour - Need some help with re-routing Midi

Great work on Ardour very excited to learn it. Have had good success, getting sound out and Midi Keyboard input.
The challenge I am facing is I am using a tool called Harmony Bloom (a generative Audio Tool) it creates midi and then I need to send it to my VST being Omnisphere.

Where can I change the midi input for the Omnisphere Channel. See attached. THX

it should look like this, I used other instr.

Is that a stand-alone Windows application, or a plugin which is loaded in Ardour?

It is a VST.

Thank you for your help. Solved.
