MIDI keyboard is disabled when Playback is Off

MIDI Input does not work when Playback is disabled. (the big power button off)
I have set Dorico to disable Playback when opening projects. This way, I can make changes without loading instruments to RAM.
MIDI Input not being available makes workflow slower in my case.
Its intended behaviour, a bug or I am doing something wrong?

Why are you creating a new thread for this when you already created one?

This just wastes time for the Dorico Team (and others) that check every post.
