How Do You Route MIDI To A Plugin?

Okay, I don’t “route” MIDI to anything. This is what I do when I record a song in Cubase.

I go to Project - Add Track - Instrument. I then pull up the instrument I want whether HALion or East West or whatever.

I then play my MIDI keyboard and it makes sounds.

I’ve never tried routing MIDI to a plugin like a reverb or delay or eq or whatever.

Please understand, I am coming from a hard wired world and don’t understand this PC stuff. In the hard wired world I had Digitech Vocalist. I piugged my MIDI keyboard directly into it via a MIDI cable and controlled it that way while also having a MIC plugged into the XLR jack and singing.

That’s what I know. That’s what I understand. This routing of MIDI via software is foreign to me. So telling me I do it the way I do everything else doesn’t help me.
