Dorico newbie here, please be gentle.
I don’t hear any notes, not when doing MIDI input, not when doing playback. It worked earlier today, now it stopped working, and I don’t know why. I’m trying to learn why so I can fix it myself in the future.
I do hear the metronome. MIDI is arriving into Dorico (I can MIDI input notes – I just don’t hear them).
I’m attaching screenshots of (what I believe are) the relevant preferences, which seem to be set correctly. My audio interface is correctly selected too.
