Vst instruments as a “Midi In” instrument – Questions & Answers

Hi everyone, I wanted to ask but in Studio One is it possible to use VST instruments as if they were “Midi In” instruments? I give an example, I load the Kontakt with a library of drums, and I want to make it “play” with Impakt, but when I go to click the drop-down menu of the “midi in” devices, Impakt does not appear! In Cubase (which I have used for years) and in Fl Studio, it is possible to do this! I am thinking for example of a Vst acting as an arpeggiator, and I want to use it for example as a midi in for Presence. I hope I have explained
