Recording Arpache 5 output to MIDI track

Faulty logic here. How do I know what I’m causing it to do to not work if it has never worked for me. This very statement presumes that I already know what variable causes it to work or not work, in which case why would I be asking the question?

I have tried any number of different things. It only works when I’m actually playing MIDI into it. Routing MIDI into it does nothing, under any circumstances.
