Does anyone uses a MKS-80 Editor in Cubase?

Hi, I have installed the MKS-80 editor from Momo Müller in Cubase to control my Roland MKS-80 hardware synth. But I don’t know how to connect it. I have it inserted as a VST-Plugin into an Instrument track. On a second MIDI track I can play the hardware but I don’t know how to connect the plugin? Any idea or experience?

No one uses an Roland MKS-80?
