Can you change midi notes appearance (sharp to flat)?

Hi, in the midi editor the midi bars representing accidentals are always set to sharp. What if I want to see them as flats? Is there a way!? Many thanks in advance…

Not at the moment, but there is a whole thread dedicated to the topic.

Seems like it is in the works though, so lets keep our fingers crossed, because it would be great.

No it will only show sharps.

There is a feature request to support both sharps & flats. You can give it some love here:
