Instacomposer: glitch & routing query

I’ve been playing with the Instacomposer demo, and I found what seems to be a bit of a glitch with the drag & drop:

It doesn’t work, when I first load it and set up a pattern, but after I load Groove Agent SE and drag a blank pattern from there, then go back to Instacomposer, the drag & drop then works.

Now, in Cubase, I can route IC’s output to a multitimbral instrument quite easily, but I don’t see how I’d do this in Dorico. Can it be done?

Dorico doesn’t support routing MIDI from plug-ins, so I don’t think you can route Instacomposer’s MIDI output to a plug-in, I’m afraid.

I thought that’s likely the case; no matter.
